FAQ

04
What does compounding frequency change?

More frequent compounding applies interest more often, so future interest is calculated on a slightly larger balance.

What is effective APY?

Effective APY is the annualized return after compounding is included, which can be higher than the stated annual rate.

Can I use this result as financial advice?

No. The result is an informational estimate based on the values you enter. Check the math, fees, taxes, and local rules before making financial decisions.
