20 Commonly Forgotten Monthly Expenses

Budgeting can take some work to get just right. One area that often trips people up is understanding exactly how much they spend each month. Figuring that out can take some trial and error as well as fine-tuning. And even if things are humming along well for a few months, you can suddenly get hit with a surprise bill or a colossal credit card statement that jeopardizes your finances.

To help avoid that scenario and make budgeting easier, it’s important to consider some of the items that are often omitted from the expenses list when people set up budgets. This can help ensure that your hard work managing your finances stays on track.

Read on to learn about commonly overlooked expenditures and how to work them into your budget. That way, you’ll know exactly where your money is going, which can help you avoid debt.

What Are Some Expenses That Are Commonly Budgeted For?

When thinking about a basic living expenses budget, some items are so major, recurring, and important that it would be hard to overlook them. These likely include:

•   Rent or mortgage payments

•   Homeowners association fees

•   Utilities

•   WiFi

•   Cell phone bill

•   Car and/or student loan payments

•   Groceries

•   Daycare or tuition

•   Gym memberships

•   Medical insurance and pet insurance premiums

•   Transportation

Why Is It Important to Budget for Forgotten Expenses?

It’s understandable that some expenses may slip your mind when creating a budget. The typical person probably has dozens of things they are paying for in a given month. But these sneaky forgotten expenses can wreak havoc on your budget and prevent you from reaching your financial goals.

That’s why it’s important to pay close attention to your spending so you can adjust your budget as needed. These are some of the reasons why it’s important to budget for forgotten expenses:

•   Creating a successful budget requires knowing what you spend each month.

•   If you forget to add an expense and run out of funds to pay for it, you may end up pulling funds out of your savings account and sacrificing future goals to cover it.

•   If you really overspend due to forgotten expenses, you may have to turn to high-interest credit card debt to make ends meet.

20 Commonly Forgotten Budget Items

If you are convinced of the importance of accounting for all of your expenses, then it’s time to move ahead. Let’s look at some commonly forgotten budget items to make sure they don’t fall through the cracks.

1. Home Maintenance

While it’s hard to forget about your mortgage payments, the other expenses of homeownership are easy to forget about and add up fast. From hiring a gardener to regular carpet cleanings to random handyman repairs, it makes sense to leave room in a budget for home maintenance as those charges tend to frequently pop up.

2. Vehicle Maintenance

Budgeting for a car payment is probably top of mind, since you likely don’t want to risk getting hit with late payment fees or losing your car. The same generally holds true for car insurance. But those aren’t the only car expenses worth planning for. Drivers also need to make room in their budget for such car-related expenses as tune-ups and repairs. You’ll also want to remember to include gas, insurance, parking and toll road fees; they also have a way of adding up.

3. Taxes

Income taxes may be withdrawn from your paychecks, but property taxes generally aren’t. Forgetting about these bills is a common budgeting mistake. Then, when the payment does come due, it’s a nasty surprise that can throw your budget out of whack.

4. Medical Expenses

It’s easy to forget about or overlook your medical expenses, including over-the-counter and Rx drugs, dental cleanings, regular checkups, or getting new glasses or contacts. These are all vital expenses worth planning for. Budgeting for medical expenses can help improve your financial health too by helping you avoid debt.

5. Donations/Giving

Perhaps you donate when you see a worthy cause on social media or sponsor a colleague who’s doing a charity walk. This kind of spending is easy to forget about, so make sure to put it into your budget so you don’t wind up short of funds when you want to help others.

6. Office/School Supplies

Items that keep your home office or study space up and running need a spot in your budget too. This means accounting for things like toner, paper, stamps, shipping supplies, and software subscription fees.

7. Renewals for Licenses (Insurance, Drivers, Etc.)

Some expenses only pop up once a year, or every few years, like driver’s license or insurance renewals, but it can be helpful to split up that expense into smaller chunks and save for it month by month.

8. Seasonal Maintenance

Some home-maintenance needs are ongoing, but others come around seasonally. Similar to license renewals, it can be helpful to save up for pricey seasonal maintenance needs, like gutter cleaning and snow removal, all year round. That way, you won’t come up short when a bill hits.

9. Items for Pets

Pets bring a lot of love into a home, but also a lot of expenses. From vet fees and pet insurance to toys, food, and doggie daycare, these expenses can be significant and deserve a place in your budget.

10. Personal Items (Hair, Nails, Etc.)

A bottle of shampoo here, a manicure there, plus regular haircuts — the myriad expenses that help us look and feel our best can add up quickly. They may only cost a few bucks a pop (hello, body wash) or only happen once in a while (that fresh set of highlights), but it’s wise to be prepared for the cost.

11. Lump Sum Bills

Some memberships and insurance plans may only renew once or twice a year. Many of them are lump sum bills, meaning you are expected to pay them in full, right away. Which is why it can be helpful to save money each month to make sure you have the funds to cover lump sum bills.

12. Ridesharing

If you rely on ridesharing apps to get around (whether it’s once a month or several times a week), it’s important to budget for that expense. The convenience can make it feel like a free ride…but it isn’t!

13. Delivery App Fees

Another app-based expense to look out for are the delivery fees that get added when you order dinner or groceries from the comfort of your home. Also, if you tip the driver, make sure to include that as well. These fees definitely add to the price of what’s being dropped off.

14. Business Expenses (Conferences, Trips, Etc.)

You may incur expenses related to work that aren’t reimbursed by your employer. These include such purchases as buying professional clothing, renewing professional licenses, or pursuing continuing education to further your career.

15. Entertainment

From travel to movies and concerts to museum memberships, there’s no shortage of entertainment costs that need to make their way into our budgets.

16. Subscriptions or Membership Fees

Speaking of entertainment, you may be paying for one or more streaming platforms, like Netflix, HBO Max, and Hulu. And you may have other subscriptions, like meal kits, personal-care supplies, gym memberships, or even a wine- or beer-of-the-month club. These kinds of one-click sign-ups may not make it onto your budget, but they should.

17. Gifts for Others

From swanky birthday dinners to holiday gifts to wedding presents, you may spend a chunk of change every year to make others happy. It can help to save for the costs of gifts all year round. You can do this by estimating how much you expect to spend in this category for the year and then break it down into a monthly expense by adding a “presents” line to your budget. That way, when these expenses do pop up, you’ll be prepared.

18. Coffee

There’s nothing wrong with enjoying a pricey latte on the go now and then, as long as it finds a spot in your budget. These kinds of little treats can be an important part of self-care, and budgeting for them properly can be an example of financial self-care.

19. Roadside Assistance Costs

One extra that some drivers may find very worthwhile is roadside assistance service. Keep it in the budget, and stay safe.

20. Laundromat/Dry Cleaners

Whether you drop off your clothing at a laundromat once a week and have them washed and folded for you, or you DIY but occasionally drop clothing off at the dry cleaner, these are all costs that need to be considered in your monthly budget.

Why Are These Expenses Commonly Forgotten?

As you can see, the list of commonly forgotten monthly expenses is long. One key reason is that it’s relatively simple to remember to add the really big, recurring expenses — like rent or a car payment — into a monthly budget. But there are plenty of “invisible” expenses that we pay for with a simple click online (whether that means paying for a subscription service or a life insurance policy) that just don’t come to mind when setting up a budget.

There are also those very infrequent charges — say, an annual technician visit to clean your heating system — that we can overlook until they hit. It’s also easy to overlook small but relatively frequent purchases, such as laundry detergent or printer paper, that can add up over time.

Accounting for as many expenditures as possible will help you hone your budget and be as prepared as possible for the bills that come your way.

Eligible Direct Deposit means a recurring deposit of regular income to an account holder’s SoFi Checking or Savings account, including payroll, pension, or government benefit payments (e.g., Social Security), made by the account holder’s employer, payroll or benefits provider or government agency (“Eligible Direct Deposit”) via the Automated Clearing House (“ACH”) Network every 31 calendar days.

Although we do our best to recognize all Eligible Direct Deposits, a small number of employers, payroll providers, benefits providers, or government agencies do not designate payments as direct deposit. To ensure you're earning the APY for account holders with Eligible Direct Deposit, we encourage you to check your APY Details page the day after your Eligible Direct Deposit posts to your SoFi account. If your APY is not showing as the APY for account holders with Eligible Direct Deposit, contact us at 855-456-7634 with the details of your Eligible Direct Deposit. As long as SoFi Bank can validate those details, you will start earning the APY for account holders with Eligible Direct Deposit from the date you contact SoFi for the next 31 calendar days. You will also be eligible for the APY for account holders with Eligible Direct Deposit on future Eligible Direct Deposits, as long as SoFi Bank can validate them.

Deposits that are not from an employer, payroll, or benefits provider or government agency, including but not limited to check deposits, peer-to-peer transfers (e.g., transfers from PayPal, Venmo, Wise, etc.), merchant transactions (e.g., transactions from PayPal, Stripe, Square, etc.), and bank ACH funds transfers and wire transfers from external accounts, or are non-recurring in nature (e.g., IRS tax refunds), do not constitute Eligible Direct Deposit activity. There is no minimum Eligible Direct Deposit amount required to qualify for the stated interest rate. SoFi Bank shall, in its sole discretion, assess each account holder's Eligible Direct Deposit activity to determine the applicability of rates and may request additional documentation for verification of eligibility.
