Use our Compound Interest Calculator to estimate your investment growth over time. Adjust the starting amount, monthly contributions, interest rate, variance, and investment period to see your projected balance and risk range.
Daily compounding is common for many savings and investment accounts.
A compound interest calculator helps you estimate how your savings can grow over time by factoring in your starting balance, regular contributions, and the effects of compounding. It allows you to project your future balance, showing both expected growth and potential ranges if your interest rate varies.
Planning your savings and investments can be challenging without knowing how your money might grow. This calculator gives you insight into how contributions, interest rates, and compounding frequency affect your wealth over time. It helps you set realistic goals, visualize growth, and understand the potential impact of market fluctuations.
The interactive chart above helps you visualize your projected balance over time, including best- and worst-case scenarios if variance is applied. You can also download your projections as a table (.XLSX or .CSV) or chart (.PNG) to track your savings progress, plan for financial goals, or share your growth estimates with advisors.
