Rounding every purchase up to the next dollar is an easy way to save without thinking. The amounts are small, which is both the appeal and the limit.
Quick wins
- Round-up features move the difference between a purchase and the next whole dollar into savings.
- Totals depend on how often you use your card, so they’re usually modest.
- Monthly fees on some apps can eat most of what you save.
- Round-ups work best alongside a regular automatic transfer, not instead of one.
Round-up savings take the spare change from your card purchases and set it aside. Spend $3.40 on a coffee, and 60 cents moves to savings.
How it works
- You link a debit or credit card to a savings feature from your bank or an app.
- Each purchase is rounded up to the next dollar.
- The difference is transferred to savings, often in batches.
What to expect
| Card use | Typical effect |
|---|---|
| A few purchases a week | A small but steady amount each month |
| Daily small purchases | More round-ups, so a larger total |
| Mostly large purchases | Fewer round-ups relative to spending |
| With a “multiplier” setting | Round-ups doubled or tripled, if your budget allows |
The total is usually modest, which is why round-ups work best as a top-up rather than your main saving.
Costs and risks
- Fees: a monthly fee of a few dollars can cancel out a small month of round-ups.
- Overdrafts: extra transfers can push a low balance below zero.
- Investing vs. saving: some apps invest your round-ups, so the value can fall. Insured savings accounts don’t carry that risk.
Money saver
Choose a round-up feature built into your own bank, if it offers one, so there’s no separate fee and the money stays in an insured account.
Heads up
If an app asks for your bank login details, check how it protects them and whether you can link accounts in a more secure way, such as through your bank’s own connection service.
Weighing it up
Round-ups are a painless way to build a habit, especially if saving feels hard. Pair them with a small automatic transfer on payday, as our guide to saving on a tight budget suggests, and the two together add up faster than either alone.
You might be wondering
Are round-ups free?
Many banks offer them free on their own accounts. Some third-party apps charge a monthly fee, which can outweigh small balances.
Can round-ups cause an overdraft?
If your checking balance is low, an extra transfer could tip it into overdraft. Check whether the feature pauses when your balance is low.
Where does the money go?
Usually into a linked savings account, though some apps invest it. Investing carries risk and isn’t the same as saving.
