3The Mathematical Power of Compound Interest
Our Compound Interest Calculator models the acceleration of your wealth over time. Unlike simple interest, which only calculates returns on your initial principal, compound interest calculates interest on your principal plus all accumulated interest. Albert Einstein famously called compound interest the 'eighth wonder of the world' because of its exponential growth properties.
How Compounding Frequencies Affect Returns
The compounding frequency is the number of times interest is calculated and added to the principal balance per year. Standard frequencies are yearly, half-yearly, quarterly, and monthly. The more frequently interest compounds, the more interest you earn because your gains begin generating their own returns sooner. While the nominal interest rate remains the same, the Annual Percentage Yield (APY) increases with higher compounding frequencies.
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.
