How This Was Calculated

The compound interest formula used:

A = P(1 + r/n)nt

Where P = $100,000.00, r = 7% (0.07), n = 12 (monthly compounding), t = 10 years. This gives A = $100,000.00 × (1 + 0.07/12)^(120) = $200,966.14.

Frequently Asked Questions

Compound interest is calculated using the formula A = P(1 + r/n)^(nt), where P is the principal, r is the annual interest rate, n is the number of times interest compounds per year, and t is the number of years. Interest earned each period is added to the principal, so future interest is earned on a larger amount.

Monthly contributions dramatically increase your final balance thanks to compound interest. Each contribution begins earning interest from the moment it's added, creating additional compounding growth. The formula extends to include the future value of an annuity.

Simple interest is calculated only on the original principal, so it grows linearly. Compound interest is calculated on the principal plus all accumulated interest, creating exponential growth. Over long periods, compound interest produces significantly higher returns.

Using the Rule of 72, $100,000 will double to $200,000 in approximately 72 / 7 = 10.3 years at 7% annual interest. With monthly compounding, it reaches $200,000 slightly faster.
