Compound Interest Calculator (Future Value & Effective Annual Rate)

Use FV = P × (1 + r ÷ 100 ÷ m) m × t . Monthly contributions can be added with C × ((1 + i) 12t - 1) ÷ i, where i is the effective monthly rate.

EAR = (1 + r ÷ 100 ÷ m) m - 1. It converts periodic compounding into an annual percentage for apples-to-apples comparison.

FAQ

How do you calculate future value with compound interest?

Use FV = P × (1 + r ÷ 100 ÷ m)^{m × t}. Monthly contributions can be added with C × ((1 + i)^12t - 1) ÷ i, where i is the effective monthly rate.

What is the Effective Annual Rate?

EAR = (1 + r ÷ 100 ÷ m)^m - 1. It converts periodic compounding into an annual percentage for apples-to-apples comparison.
