💰 Savings Interest Calculator
Visualize your financial future. Calculate the compound interest on your savings and see your wealth grow over time.
The Power of Compounding
This calculator uses the future value formula for a series with regular contributions:
A = P(1 + r/n)ⁿᵗ + PMT × [((1 + r/n)ⁿᵗ - 1) / (r/n)]
Understanding the Formula
The growth of your savings is calculated using the formula for the future value of a series, which accounts for both your initial lump sum and your ongoing periodic contributions. It’s a combination of two powerful financial concepts:
- Compound Interest on Initial Principal: The first part,
P(1 + r/n)ⁿᵗ, calculates the future value of your initial investment (P) as it compounds over time. - Future Value of Contributions: The second part,
PMT × [((1 + r/n)ⁿᵗ - 1) / (r/n)], calculates the future value of your series of regular monthly payments (PMT). Each payment has time to grow, and this formula sums up the future value of all of them.
By adding these two results together, we get the total future value of your investment, accurately reflecting how both your initial capital and your consistent savings efforts contribute to your wealth.

5. FAQs
Q: What is compound interest?
A: Compound interest is “interest on interest.” It is the process where the interest you earn on your savings or investment is added back to the principal amount. In the next period, you earn interest on this new, larger principal. This causes your wealth to grow at an accelerating rate over time.
Q: How is the interest compounded in this calculator?
A: This calculator assumes that interest is compounded monthly. This is a common frequency for many savings accounts and investment vehicles. Your monthly contributions are also factored in at the end of each month.
Q: Can I use this calculator for investments with fluctuating interest rates?
A: This tool is designed for a fixed annual interest rate to provide a clear projection. For investments with variable rates, you can use an average expected rate for long-term planning. You could also run multiple calculations with different rates to see a range of possible outcomes.
Q: Does this calculator account for inflation or taxes?
A: No, this calculator does not factor in inflation or taxes on interest earnings. The results show the nominal future value. To understand your real return, you would need to subtract the expected inflation rate from your interest rate and account for any applicable taxes separately.
Q: Is my financial data saved?
A: Absolutely not. This is a client-side tool, meaning all calculations are performed directly in your browser. None of your financial information is sent to, or stored on, any server. Your privacy is 100% guaranteed.
