Savings Calculator
Estimate how your savings grow over time with compound interest.
How the Savings Calculator Works
This savings calculator uses the compound interest formula to estimate how your money grows over time. It considers your starting balance, monthly savings contributions, annual return rate, and compounding frequency. The calculator then projects future savings based on these inputs.
The core formula used is:
Future Value = P × (1 + r)n + PMT × [(1 + r)n − 1] / r
Use this tool for long-term financial planning, emergency fund goals, retirement savings analysis, and comparing deposit strategies.
Inputs Explained
Starting balance: The amount you currently have saved.
Monthly savings amount: The amount you plan to save each month. Even small consistent amounts make a large difference over time due to compounding.
Annual interest rate: The percentage your savings earns per year. Savings accounts, high-yield accounts and investment returns vary widely.
Years: The duration your savings will grow.
Compounding frequency: How often your interest is added to your balance. Daily or monthly compounding yields slightly higher final values than yearly compounding.
Outputs Explained
Final savings value: The projected total amount at the end of the selected period.
Total contributions: The combined total of all deposits made into the account.
Use this calculator for emergency fund planning, short-term goals, long-term savings strategies and habit tracking.
