Frequently asked questions
What is future value? ›
Future value (FV) is what an asset or investment is worth at a specific point in the future, assuming a given rate of return. It accounts for compound interest — earning returns on both the principal and previously earned interest. FV is used to plan for retirement, education savings, and any long-term financial goal.
What is the difference between simple and compound interest for future value? ›
Simple interest calculates growth only on the original principal. Compound interest calculates growth on principal plus all previously earned interest — creating exponential growth. For long time horizons, the difference is enormous. $10,000 at 7% simple interest for 30 years = $31,000. At 7% compound = $76,123.
How does compounding frequency affect future value? ›
More frequent compounding produces slightly higher returns. Monthly compounding (12x/year) produces a bit more than annual compounding. Daily compounding produces slightly more than monthly. The difference becomes more meaningful at higher interest rates and over longer periods.
What is the Rule of 72? ›
The Rule of 72 is a quick shortcut: divide 72 by the annual interest rate to estimate how many years it takes to double your money. At 7%, money doubles in ≈10.3 years (72÷7). At 9%, it doubles in ≈8 years. It's a fast mental math check for any investment.

About this future value calculator

This calculator computes the future value of any investment or savings — with or without regular contributions — using the standard compound interest formula. It supports four modes: solve for future value, present value, interest rate, or time period.

The growth table shows your balance year by year, making it easy to see when compound interest really starts accelerating. This is the same calculation used in retirement planning, 529 college savings plans, and any long-term financial goal.
