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.

Is this financial advice?

No. Results ignore taxes, fees, and personal circumstances. Always consult licensed professionals before investing.
