Spare Change Savings

Saving spare change and using round-up apps can help you bolster your savings, possibly in a meaningful way. Spare change savings (also known as “micro-saving”) can be a great way to kickstart your savings and also help you start automating your finances.

However, not all spare change apps are created equal. Some charge fees, which can quickly erode your savings. And some invest your savings, which adds an element of risk that may not be ideal if you’re focused on a short-term goal.

Here are some key things you may want to keep in mind when choosing a spare change savings app.

Key Points

•   Spare change savings apps round up purchases to the nearest dollar, transferring the difference to savings or investments.

•   Benefits include automated savings, earning interest, and easier entry into investing.

•   Drawbacks can include fees, investment risks, and potential overdraft issues.

•   Choose an app that aligns with financial goals, has low fees, and ensures security.

•   Some banks offer similar rounding features, providing a no-fee alternative to third-party apps.

How Does Spare Change Saving Work?

The philosophy behind spare change savings is “little and often.” Every time you spend money, whether it’s on gas, groceries or dining out, an app rounds up that purchase and saves the change for you.

Spare change savings apps typically connect to your credit and/or debit card, take the virtual change from your linked checking account, and put the money into a savings account. For instance, if you buy a sandwich for $5.80, the app will automatically transfer 20 cents from your checking account into a savings account. It’s one way to automate your finances. Little by little, this cash can accumulate and help you reach goals, such as starting an emergency fund.

Some spare change apps put your money into a traditional savings account or a checking and savings account. Others invest your money in small portfolios, based on your risk tolerance and financial situation. There are also spare change apps that use saved funds to pay off debts that you designate, such as credit cards or student loans.

The Benefits of Spare Change Savings

There are a number of potential benefits to spare change savings. Below are some of the reasons you may want to try using one of these apps.

Makes Saving Easy and Automatic

One of the biggest advantages of spare change savings is that it’s automatic. You don’t have to remember to bring your change to the bank or transfer money from checking to savings after you get paid in order to save money from your salary. And, unlike the change jar, the money saved is out of sight and out of mind.

If you’re struggling to save money, setting up a spare change savings app can help jumpstart the process and make it relatively pain-free.

Allows Your Savings to Earn Interest

Unlike the piggy bank method, a spare change app can put your savings into an account that can earn interest, such as a high-yield savings account, and help your money grow over time.

Can Make Investing Less Intimidating

Some spare change savings apps, known as “micro-investing” apps, will offer users the opportunity to invest their money in stocks, bonds, and/or exchange-traded funds (ETFs). This involves risk, mainly because of market volatility and the lack of insurance for investment products.

Micro-investing apps can make it easier to get started with investing, even if you currently don’t know anything about it. Generally, they’ll recommend a portfolio based on your goals and time horizon, turning your spare change into an investment on a small scale, such as through fractional stock shares or small dollar purchases of other investment products, which can be a good way to experiment.

May Provide Other Ways to Save

Some spare change savings apps partner up with other brands that will kick in a percentage of every purchase you make to your savings account. For example, if an app partners with Macy’s or Apple, every time you make a purchase from one of those retailers, a small percent of the total you spend would get added to your savings account (in addition to the round-up amount taken from your checking account).

Disadvantages of Spare Change Savings

There are some potential downsides to spare change savings apps. Here are a few drawbacks you may want to consider before signing up for one of these apps.

May Charge Fees

Some spare change apps charge monthly (and other) fees for using their services. Before signing up for an app, it’s a good idea to read the fine print and look into what, if any, fees you may be charged and how often.

Even if the fees are small, they could quickly eat into your savings, especially since the dollar amounts you’re putting away are small.

Could Lose Money Through Investing

If you choose to put your spare change savings into investments, there is some risk involved. Depending on market fluctuations, your money could grow. On the other hand, you could potentially lose some or all of your savings.

May Not Be Ideal for Emergency Funds

If you go with an app that invests your savings, you may not be able to access the money immediately, which could be an issue if you’re faced with a financial emergency.

Another potential problem is that if your account is down in value at the time you need to withdraw the money, you would have to take a loss instead of waiting for market conditions to improve. In this scenario, it might be wiser to keep your funds in a traditional or online bank account.

Might Trigger an Overdraft Fee

If your checking account is close to zero after you make a transaction, and then the spare change app rounds-up the transaction and withdraws additional funds, you could end up overdrafting your account. This could result in getting hit with a hefty overdraft fee.

The Takeaway

While each spare change app functions slightly differently, they all revolve around the same basic concept: You save small increments of cash that you likely won’t miss. The money gets put into a savings account. You can then use the money to work toward your savings goals. If the concept appeals to you, you might look for a bank that offers this feature or try a third-party app.

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.
