Guide To Static vs Flexible Budgets

A budget is a great way to take control of your money: It gives you vital intel about your earnings, spending, and saving while providing guidance so you can hit your financial goals.

That said, a key step in the budgeting process is finding the right technique for you. Which is why it can be helpful to learn about two different budget types that are often used in business accounting. The two varieties, a static budget and a flexible budget, can apply them to your personal finances.

A static budget presets your spending limits per category, but doesn’t vary with real-time events, like an unexpected car repair bill or low-earning quarter. When you use a flexible budget, however, you can adjust amounts month by month or even week after week.

Depending on your personal and financial style, one type of budget may work better than another for you. This guide will explain each approach and spell out their pros and cons so you can pick what will work best for you.

What Is Flexible Budgeting?

What is a flexible budget? It’s a way of tracking and managing your money that relies on current information. It does not stay fixed. Rather, you can review the data — what’s coming in and what’s going out — and adjust accordingly. So if a client doesn’t pay his bill one month as you expected or an unexpected expense pops up, you can juggle things around a bit.

You might temporarily cut some discretionary expenses, such as entertainment or clothing, for example.

💡 Quick Tip: Want to save more, spend smarter? Let your bank manage the basics. It’s surprisingly easy, and secure, when you open an online bank account.

What Is Static Budgeting?

A static budget vs. a flexible budget is more rigid. Sometimes referred to as a master budget, a static budget can be a good way to establish financial guardrails. You always know how much you have allotted to pay for certain expenses.

Say you typically spend $500 a month on groceries. In a static budget, that is the amount that will be earmarked, regardless of whether, say, you are throwing a 30th birthday party for a pal and need to load up on supplies for charcuterie boards.

The budget won’t vary, and you may perhaps have to figure out how to make it work.

Comparing Static vs Flexible Budgeting

Here, you’ll learn about the differences between static vs. flexible budgets by exploring the pros and cons of each.

Pros and Cons of Flexible Budgeting

Here’s a closer look at flexible budgeting, starting with the upsides.

Pros of Flexible Budgeting

If you review the different budgeting methods and choose a flexible one, you will likely enjoy these positives:

•   Reflects income fluctuations. If you work as a freelancer, a seasonal employee, or on commission, you are used to the ups and downs of your earning. With a flexible budget, this variation is acknowledged and addressed.

•   Adjusts for changing expenses. A flexible budget can help you account for shifts in spending, such as needing to shell out for a new phone or getting a month of free rent when you move to a new apartment.

•   Allows for spontaneity. It can let you jump on an opportunity, like a chance to go to London for half-price when you find a killer deal online.

Cons of Flexible Budgeting

Next, consider the downsides of flexible budgeting.

•   Requires time and energy. Because it isn’t a “set it and forget it” method of budgeting, it means you need to check in regularly on your income, spending, and saving to stay on track.

•   Limits your ability to plan. Since you are adjusting and recalibrating, that may detract from how well you can map out and achieve your financial goals.

•   May minimize accountability. If you know your budget is flexible, you may feel as if you have license to deviate from your money management habits. You may give yourself permission to overspend (like that half-price trip to London mentioned above.)

Pros and Cons of Static Budgeting

Here’s the lowdown on static budgets so you can decide if they suit your personal and financial style.

Pros of Static Budgeting

First, the positives about these budgets:

•   Provides structure. A static budget is a rigorous way of tracking and managing your money. You determine how much cash goes where and then follow those guidelines. It tells you what you can and can’t do month to month.

•   Needs little maintenance. As mentioned before, this is a “set it and forget it” type of plan, not one that needs constant adjustment.

•   Can enhance goal-setting. This kind of plan helps you prioritize and follow through. If you are trying to sock away money for the future (whether that means a vacation next year or the down payment on a house several years down the road), a static budget can help you hit your marks without fail.

Cons of Static Budgeting

That said, there are downsides to static budgets:

•   Can be too rigid. Life happens: You try the new Brazilian steakhouse in your neighborhood and blow your dining out budget. You get hit with an unexpected car repair bill. A static budget doesn’t give you wiggle room.

•   Can be discouraging. A corollary to the above point: Some people feel less motivated to follow a budget when they feel it doesn’t “get” what’s going on in their life. It may lead them to be less diligent about tracking their expenses and money in general.

If you aren’t sure which budgeting method is best for you between static budgets and flexible budgets, a hybrid approach might be appropriate. That could include:

•   Setting up a master budget at the beginning of the year based on projections and using it as a guide.

•   Tracking costs as the year progresses and making adjustments when necessary.

•   Using that information and learning to better inform next year’s plan.

7 Steps to Start Budgeting

The point of a budget — whether you’re a freelancer or a full-time employee — is to spend less than you earn so you can save and reach future financial goals. Here are a few steps for budgeting for beginners; they could help you get started.

💡 Quick Tip: If you’re saving for a short-term goal — whether it’s a vacation, a wedding, or the down payment on a house — consider opening a high-yield savings account. The higher APY that you’ll earn will help your money grow faster, but the funds stay liquid, so they are easy to access when you reach your goal.

1. Figuring out What You Spend

If you aren’t already tracking your spending, that may be a good place to begin. There are several ways to do this, from carrying around a small notebook and writing down every expense to using a spreadsheet to downloading an app on your phone (your financial institution may offer a good option).

•   Understand your fixed expenses. Once you’ve tracked your spending for a few months, you can determine your average spending in various recurring categories. Some of this will be fairly easy, because the costs are often the same (housing, car payment, student loans, etc.).

•   Get a handle on variable expenses. Your discretionary expenses will likely vary from month to month or at different times of year. Utility costs may go up or down, for instance, depending on the season. Or your travel costs may go up if you take a summer vacation. And some costs, such as clothing, entertainment, and household goods, will be more discretionary than others.

•   Don’t skip important items. Be sure to include commonly forgotten expenses, such as pet-care costs and charitable donations. If you’re self-employed, you may want to consider taxes, retirement savings, insurance, and other expenses that others might have automatically withdrawn from their paychecks every month.

2. Determining What You’ll Earn

Pinning down how much you can expect to earn is often much easier for those with regular paychecks. If you’re self-employed but have steady clients who pay on time, or your job is a mix of paychecks and tips or commissions, you may be able to come up with a fairly accurate estimate.

But if you’re a freelancer or contractor whose work and pay varies widely from month to month, it can be a challenge to set this amount.

•   Example: You can use your spreadsheet or tracking app to determine an average amount earned ($4,000 in July + $5,000 in August + $3,000 in September would be $4,000 a month, for example). This may give you a more realistic number on which to base your budget calculations than guessing (or hoping) that you’ll make a certain amount.

3. Creating a Budget Using What You’ve Found

Here’s where you can make a budget that you want to use.

•   With a static budget, you would set spending limits and stick with them throughout the year.

•   With a flexible budget formula, you would set spending limits, but adjust when necessary: If you make less than expected, you spend less than you planned.

•   If you see that you’re spending more in one category than expected, you can shift allocations or find ways to cut recurring costs like your cable bill, haircuts or pedicures, or gym membership.

•   If it looks as if you’re headed for a long-term shortfall, and you just can’t cut it any tighter, you may have to find a way to earn extra money by taking on a side gig or perhaps raising your freelance rates. What’s important is setting a realistic budget, so you can stick with it.

4. Considering the 50/30/20 Plan

Looking for flexibility, but don’t want a budget you have to rework every month? You may be a candidate for the 50/30/20 budgeting method, which was made popular by Sen. Elizabeth Warren and her daughter, Amelia Warren Tyagi.

The plan suggests the following:

•   Putting 50% of after-tax income toward essentials like rent and food, as well as minimum debt payments.

•   Allocating 30% toward discretionary spending, or the fun stuff in life.

•   Committing 20% toward savings.

This method also makes sense for people who are on a steady salary as well as those who don’t have a steady income, because it’s based on percentages. And those percentages are just a guideline for getting started, so you can shift the amounts to make it work for your finances.

You can save more or less, depending on what you’re earning or what long-term debts you have. Or you might move a few percentage points from discretionary spending to cover essentials if you live in a city with higher housing or transportation costs.

5. Building a Backup Fund

If possible, consider making an emergency savings account a priority. Life has unexpected ups and downs for everyone, and financial experts’ recommend that you build up to three to six months’ worth of living expenses in the bank.

This can help protect you if, say, you were to lose your job or face a large, unexpected expense. It can help you stay afloat and avoid racking up high-interest credit card debt.

An emergency fund can be especially important for freelancers and other self-employed workers. If you have a slow month or quarter (or get injured or sick), that money can tide you over.

Even if saving anything at all seems daunting, don’t worry or give up. Starting small, with a $100 or $200 deposit or the addition of $20 at a time can be better than never starting at all.

6. Splurging Responsibly

With a personal budget, cost-cutting measures can be a sign of fiscal responsibility, but if you can’t splurge every once in a while, it may make it harder to stick to your overall plan.

So how can you splurge responsibly? Living on a budget doesn’t mean you don’t get to have fun! Maybe you earmark $25 a week for fun little purchases if you’re the kind who loves getting a gelato or buying a book from time to time. Or you might choose to put any bonuses, unexpected earnings, and tax refunds straight into the bank with a trip or some other big spend in mind.

Or you could build the extravagance into your budget, with a category specifically for vacations or travel, or one for home renovations, and deposit that amount into a separate account just for that purpose.

7. Thinking About Tomorrow

A smart personal finance budget involves saving for retirement. Many experts recommend signing up ASAP if your employer offers a 401(k) or some other retirement plan — especially if there’s a matching contribution involved. If an employer plan isn’t available to you, you may still want to make it a goal to invest something each month in a traditional IRA, Roth IRA, or Simplified Employee Pension (SEP) IRA.

With a traditional IRA or SEP, you can defer paying taxes on the money you invest until you take withdrawals in retirement, which can keep you in a lower-tax bracket.

Or, if you’re nervous about tying up the money that long, you could go with an after-tax Roth account, which allows you to withdraw contributions (but not earnings) at any time. You can open an IRA at a brokerage, bank, or other financial services provider.

FAQ

What is the difference between a fixed and flexible budget?

Here’s the difference between a fixed vs. flexible budget: With a fixed budget, it’s expected that your income, spending categories, and savings will remain constant. With a flexible budget, there is wiggle room for adjusting and updating these numbers.

What is an example of a fixed budget?

With a fixed budget, the numbers for earnings, spending, and saving would be set and then stay constant. It would be assumed, say, that your housing expenses, your dining out and clothing spending, and your retirement savings will be steady, month after month.

What is an example of a flexible budget?

An example of a flexible budget is one that varies and takes into account the ups and downs of income, spending, and saving. For instance, it might add a category for gift-buying in December as the holidays approach, or drop in a sum of vacation spending in July.

SoFi members with direct deposit activity can earn 4.60% annual percentage yield (APY) on savings balances (including Vaults) and 0.50% APY on checking balances. Direct Deposit means a deposit to an account holder’s SoFi Checking or Savings account, including payroll, pension, or government payments (e.g., Social Security), made by the account holder’s employer, payroll or benefits provider or government agency (“Direct Deposit”) via the Automated Clearing House (“ACH”) Network during a 30-day Evaluation Period (as defined below). Deposits that are not from an employer or government agency, including but not limited to check deposits, peer-to-peer transfers (e.g., transfers from PayPal, Venmo, etc.), merchant transactions (e.g., transactions from PayPal, Stripe, Square, etc.), and bank ACH funds transfers and wire transfers from external accounts, do not constitute Direct Deposit activity. There is no minimum Direct Deposit amount required to qualify for the stated interest rate.

SoFi members with Qualifying Deposits can earn 4.60% APY on savings balances (including Vaults) and 0.50% APY on checking balances. Qualifying Deposits means one or more deposits that, in the aggregate, are equal to or greater than $5,000 to an account holder’s SoFi Checking and Savings account (“Qualifying Deposits”) during a 30-day Evaluation Period (as defined below). Qualifying Deposits only include those deposits from the following eligible sources: (i) ACH transfers, (ii) inbound wire transfers, (iii) peer-to-peer transfers (i.e., external transfers from PayPal, Venmo, etc. and internal peer-to-peer transfers from a SoFi account belonging to another account holder), (iv) check deposits, (v) instant funding to your SoFi Bank Debit Card, (vi) push payments to your SoFi Bank Debit Card, and (vii) cash deposits. Qualifying Deposits do not include: (i) transfers between an account holder’s Checking account, Savings account, and/or Vaults; (ii) interest payments; (iii) bonuses issued by SoFi Bank or its affiliates; or (iv) credits, reversals, and refunds from SoFi Bank, N.A. (“SoFi Bank”) or from a merchant.

SoFi Bank shall, in its sole discretion, assess each account holder’s Direct Deposit activity and Qualifying Deposits throughout each 30-Day Evaluation Period to determine the applicability of rates and may request additional documentation for verification of eligibility. The 30-Day Evaluation Period refers to the “Start Date” and “End Date” set forth on the APY Details page of your account, which comprises a period of 30 calendar days (the “30-Day Evaluation Period”). You can access the APY Details page at any time by logging into your SoFi account on the SoFi mobile app or SoFi website and selecting either (i) Banking > Savings > Current APY or (ii) Banking > Checking > Current APY. Upon receiving a Direct Deposit or $5,000 in Qualifying Deposits to your account, you will begin earning 4.60% APY on savings balances (including Vaults) and 0.50% on checking balances on or before the following calendar day. You will continue to earn these APYs for (i) the remainder of the current 30-Day Evaluation Period and through the end of the subsequent 30-Day Evaluation Period and (ii) any following 30-day Evaluation Periods during which SoFi Bank determines you to have Direct Deposit activity or $5,000 in Qualifying Deposits without interruption.

SoFi Bank reserves the right to grant a grace period to account holders following a change in Direct Deposit activity or Qualifying Deposits activity before adjusting rates. If SoFi Bank grants you a grace period, the dates for such grace period will be reflected on the APY Details page of your account. If SoFi Bank determines that you did not have Direct Deposit activity or $5,000 in Qualifying Deposits during the current 30-day Evaluation Period and, if applicable, the grace period, then you will begin earning the rates earned by account holders without either Direct Deposit or Qualifying Deposits until you have Direct Deposit activity or $5,000 in Qualifying Deposits in a subsequent 30-Day Evaluation Period. For the avoidance of doubt, an account holder with both Direct Deposit activity and Qualifying Deposits will earn the rates earned by account holders with Direct Deposit.

Members without either Direct Deposit activity or Qualifying Deposits, as determined by SoFi Bank, during a 30-Day Evaluation Period and, if applicable, the grace period, will earn 1.20% APY on savings balances (including Vaults) and 0.50% APY on checking balances.

Interest rates are variable and subject to change at any time. These rates are current as of 10/24/2023. There is no minimum balance requirement. Additional information can be found at https://www.sofi.com/legal/banking-rate-sheet.
