Saving and investing money is a lot like eating broccoli. We know we should do it, but it's not so easy. One easy way to save money is with an automatic savings app. To help you get started, here are the best round-up apps for both savings and investing.

Best Overall Round-Up App for Investing–Acorns

Acorns App

Acorns is my pick for the best overall round-up app for investing. Acorns is one of the first round-up apps with over 9 million clients. It offers both low cost investing, free checking and a free debit card. As such, it works for savings, investing or both.

After creating an account, you link the credit and debit cards you use for spending. Acorns tracks your round-ups and transfers them from your linked checking account once they reach $5.

You choose how you want Acorns to invest your round-ups. Users can select from several pre-configured portfolios, ranging from conservative (100% bonds) to aggressive (100% stocks). You can also chose among socially responsible portfolios. Acorns does the rest, making the investments for you in low cost, diversified ETFs (Exchange Traded Funds).

Acorns Investment Options

For savers, Acorns offers a checking account and debit card. The FDIC-insured account offers direct deposit, mobile check deposit and free nationwide ATMs. It does not, however, pay interest on its checking account.

Acorns costs just $3 a month for a personal account. The fee covers investing and checking accounts. For $5 a month, get the family plan that enables kids to start investing early.

Best Overall Round-Up App for Savings–Chime®

For those focused on building an emergency fund or other savings, Chime is my top pick for round-up apps. Why? Unlike most round-up apps, Chime pays interest on your savings.

Chime comes with a long list of features:

  • Get paid up to 2 days early with direct deposit*
  • Fee-free overdraft protection of up to $200 for eligible members**
  • Over 60,000 fee-free ATMs***
  • Savings earn interest (currently 2.00% APY^)

It's key feature for our purposes is automated savings. Chime automates savings in several ways.

First, it does have a round-up feature. Called “Save When You Spend,” Chime will round up to the nearest dollar purchases made with its free Visa debit card. Chime then transfers the round-up from your Chime Checking Account to your Savings Account.^^

Second, Chime enables customers to setup automatic savings. After each paycheck, you can have an amount of your choice automatically moved from your Chime Checking Account to your Savings Account.

There are other things I like about Chime. It has arguably one of the best secured credit cards to help customers build their credit. It's called the Secured Chime Credit Builder Visa® Credit Card, charges no annual fee and has no required minimum security deposit.^^^

Full List of Round-Up Apps

In addition to Acorns and Chime, here are several other round-up apps worth considering.



Best for kids and teens

Greenlight is perhaps best known for offering a debit card for kids and teens. It also offers an investing platform to teach young people the importance and power of saving and investing. With Greenlight Max, kids can invest in their favorite companies or ETFs. There are no trading fees and parents must approve all trades.

Greenlight Max investing

Greenlight offers several ways to encourage savings through what it calls Savings Boosts. One Savings Boost is round-ups. Transactions are rounded up to the nearest dollar and transferred to savings. Other Savings Boosts include earning 1% cash back on all purchases and up to 2% interest on their savings.

In addition to investing, Greenlight can serve as a child's bank and budgeting app. Monthly costs range from $4.99 to $9.98 a month for up to five children.



Best for microinvesting

While all round-up apps are a form of microinvesting, Qapital takes it to another level. In addition to round-ups, Qapital offers a number of Rules that will trigger automatic saving and investing:

  • Payday Divvy: This feature enables you to automate how much of your paycheck goes to spending, savings and investing.
  • Set and Forget: Set up automatic transfers to savings or investing every week.
  • Guilty Pleasure: Enjoy your morning coffee at Starbucks, but save some money at the same time. You can designate the merchants and how much you save each time you shop there.
  • Spend Less Rule: Set a spending limit at the grocery store and automatically save the difference between the set amount and what you typically spend.
  • Freelancer Rule: For 1099 workers, you can set a percentage of all deposits of $100 or more to be transferred to Qapital's FDIC-insured account for estimated taxes.
  • 52 Week Rule: Save $1 in week one, $2 in week two, and so on, for a total of $1,378 over the course of a year.
  • Apple Health: Set automatic transfers to savings each time you walk, bike or run.

Money saved can be invested in one of several portfolios using low-cost ETFs:

Qapital portfolios

Qapital offers three plans ranging from $3 to $12 a month.

Other Round-Up Apps

I continue to evaluate round-up apps and will update this article based on new research. Here are other apps I'm evaluating:

  • Digit
  • Empower
  • MoneyLion
  • N26
  • Betterment
  • Worthy Bonds
  • Current

It's worth noting that some banks offer round-up features. Bank of America is one example. The problem is that its interest rates on savings accounts are terrible.

How Round-Ups Work

Round-up apps bring the concept of a change jar into the digital world. When cash was king, it was common to have a change jar in the house. Each day when you got home, you took the change out of your pocket and put it in the jar. It wasn't a lot of money, so it didn't crush the budget. And while each deposit into the jar didn't amount to much, over time it grew into some serious cash.

Round-up apps take the same concept and apply it in the world of electronic payments. You connect your checking account and credit cards to the round-up app. The app then keeps track of your transactions and the round-up amount. For example, if you spend $3.74 at a coffee shop, the app adds $0.26 to your round-up balance.

Once your round-ups reach a threshold (typically $10), the app transfers the amount from your checking account to either a savings or investment account. As such, round-ups are one form of microinvesting.

The Psychology Behind Automatic Savings

There are several psychological “tricks” that make round-up apps so effective. First, they require just one easy decision. Once you turn on the round-up feature, it continues to work without any additional effort on your part. This simple decision makes it easy to overcome the status quo bias. And once overcome, the round-ups become the status quo.

Second, they are automatic. The round-ups don't require us to make decisions each day, week or month. They happen behind the scenes, even if we forgot all about them.

Finally, round-ups involve relatively small amounts of money. Trying to save hundreds of dollars a month might feel daunting. Saving our spare change every day, on the other hand, is less intimidating even if it adds up over time.

Can Round-Ups Really Make a Difference?

Yes. In fact, one study found that saving even $100 had a profound effect on financial well-being. And with the power of compounding, even small amounts of money saved over time can grow into significant wealth. For example, investing just $50 a month over a working career can grow into more than $400,000 at a 10% return.

Of course, returns aren't guaranteed and a working career can last 40 or 50 years. At the same time, $50 a month is not exactly a flood of money. It's a start. Continue to increase your savings and your wealth will continue to compound over time. In the end, compounding will generate for more wealth than the amounts you actually save.
