Frequently asked questions

What does Nominal Interest Rate Calculator do?

Work back from an effective rate (APY/EAR) to the stated nominal rate.

When would I actually use this?

Planning a deposit, a safety net or a large purchase: how much to put aside each month, and how long a target takes at a given rate.

What is the most common mistake?

Reading a nominal rate as if it were real. Inflation is subtracted from the return, not from the capital, so a 3% account during 4% inflation loses purchasing power every year.

How is Nominal Interest Rate Calculator different from Interest Rate Calculator?

They sit next to each other but answer different questions: Interest Rate Calculator is the one to open when you need it to find the interest rate of a loan from its amount, term and monthly payment. Pick whichever matches what you're starting from — both are free.

Is there a tool for the next step?

Compound interest calculator is the closest one after this: See how your money grows with compound interest and contributions.

What else is worth having open alongside it?

Simple interest calculator and Percent Growth Rate Calculator — they come up in the same task often enough to be worth a second tab.

Where do the figures come from?

Compound interest is arithmetic, so the maths is exact for the rate you enter. Real accounts vary in compounding frequency, tax treatment and whether interest is credited before or after a deposit.
