Round-up Investing Estimator
How spare change from round-ups adds up over a year.
Enter a typical week: how much you spend, how many transactions get rounded up, and the average round-up on each one. The monthly and annual figures are that weekly spare change, stretched across the year. Nothing is invested for you.
Each year
14 round-ups of $0.45 is $6.30 a week, about $327.60 a year.

Worked example
$280 spent across 14 transactions, with an average round-up of $0.45, sets aside $6.30 a week. That’s about $27 a month and about $328 a year — spare change that adds up if you keep it going.
FAQ
- What is an average round-up?
- The typical spare change on one transaction, such as $0.40 when a $4.60 coffee rounds to $5. You supply the average.
- Does the weekly spend change the total?
- The dollars set aside come from the transaction count times the average round-up. Spend is only used to show what share of the week that is.
- Is the money invested?
- No. The page estimates the micro-investment total. It does not buy anything.
