How does this calculator work?

This savings calculator models an account period by period. It begins with the starting balance, adds each regular contribution at the timing you select, calculates interest using the nominal rate and compounding frequency, rounds that credit to cents, and carries the new balance into the next period. The APY is derived from the Regulation DD annual-yield formula so accounts with different compounding schedules can be compared. It does not forecast changing rates, fees, taxes, or inflation.

What questions do people ask about this calculator?

How does a savings calculator work?

It starts with your existing balance, adds a regular contribution on the selected schedule, credits interest each period, and repeats that cycle for the number of years you enter.

Is the rate the same as APY?

No. The nominal rate is the quoted annual rate before compounding. APY includes the effect of compounding and is the better number for comparing accounts.

Should I enter contributions at the beginning or end?

Choose the timing that matches when money reaches the account. Beginning-of-period deposits earn that period’s interest; end-of-period deposits do not.

Does this calculator include inflation or taxes?

No. Results are nominal and before tax. Inflation changes purchasing power, and taxable interest may create a tax liability.

Why is my bank statement a few cents different?

Banks can use daily balance methods, different posting dates, and different half-cent rounding rules. This calculator uses a transparent period-by-period model and rounds each credit to cents.

Should I compare savings accounts by rate or APY?

Compare APY when the accounts have different compounding schedules. It combines the quoted rate and the compounding effect into one annualized yield.
