📈 Savings Account Interest Calculator
Visualize your financial future and understand the power of compound interest.
The Formula for Financial Growth
Understanding how your savings grow is the first step toward financial empowerment. The calculations in this tool are based on two core financial principles: the formula for compound interest and the formula for the future value of a series (for regular contributions).
Compound Interest Formula
This formula calculates the future value of your initial deposit.
- A = the future value of the investment/loan, including interest.
- P = the principal investment amount (the initial deposit).
- r = the annual interest rate (in decimal).
- n = the number of times that interest is compounded per year.
- t = the number of years the money is invested for.
Future Value of a Series Formula
When you make regular contributions, we use this formula to find their future value.
- FV = the future value of the series of payments.
- PMT = the amount of each regular payment.
- All other variables are the same as the compound interest formula.
The calculator combines these formulas to give you a total future value based on your initial deposit and your ongoing contributions.
The Formula for Financial Growth (Recap)
As a reminder, this calculator uses the standard financial formulas for compound interest and future value of a series to project your savings. By adjusting inputs like your contribution amount or the compounding frequency, you can see how these formulas work in real-time to affect your financial outcome.

Frequently Asked Questions (FAQs)
1. Is this calculator based on simple or compound interest?
This calculator exclusively uses compound interest, the standard for savings accounts where you earn interest on both your initial principal and the accumulated interest. This is what leads to exponential growth over time.
2. How accurate are the results?
The calculations are based on standard financial formulas and are highly accurate for the data you provide. However, they are projections and do not account for factors like taxes on interest, bank fees, or inflation. Use them as a powerful planning guide.
3. Can I save or print my results?
For your privacy, we do not save your data. However, you can easily use your browser's print function (Ctrl/Cmd + P) to save your results page, including all charts and the table, as a PDF or print a hard copy.
4. What currencies does the calculator support?
Our calculator is built for a global audience and supports US Dollar (USD), Euro (EUR), British Pound (GBP), Indian Rupee (INR), and Japanese Yen (JPY). All results will be formatted with the correct currency symbol.
5. How much difference does compounding frequency make?
It can make a noticeable difference over long periods. More frequent compounding (like daily) means your interest starts earning its own interest sooner. Use the "Compounding Frequency" dropdown to compare scenarios and see for yourself!
