Frequently Asked Questions (FAQ)
What is the difference between simple and compound interest?
Simple interest is calculated only on the principal amount of a loan or deposit. Compound interest is calculated on the principal plus any accumulated interest from previous periods.
How does the Rule of 72 work?
The Rule of 72 is a quick mental formula to estimate when an investment will double. Divide 72 by your expected annual interest rate. For example, an investment earning 8% p.a. will double in approximately 9 years (72 / 8 = 9).
How do I use a compound interest calculator with monthly payments?
Input your starting principal, additional monthly payments, expected annual interest rate, duration in years, and compounding frequency to calculate the future value of your portfolio.
