How Does Round-Up Investing Work?

1

Link Your Card

Connect a debit or credit card. Every purchase you make gets monitored for round-ups.

2

Spare Change Gets Swept

A $4.30 coffee becomes a $5.00 charge โ€” the $0.70 difference flows into your investment account.

3

Compound Over Time

Those tiny amounts get invested in a diversified ETF portfolio and compound year after year.

This calculator is for educational purposes only. Results assume consistent monthly round-up contributions and a fixed annual return with monthly compounding. Actual investment returns vary and are not guaranteed. Past market performance does not predict future results.
