Summary: how to calculate savings growth for free and privately
A savings calculator projects how much money you will have after a set number of years from what you have saved, what you add each month and the interest you earn. Enter your Initial Savings, Monthly Contribution, Annual Interest Rate and Savings Period (Years), and the calculator shows the total balance, the split between contributions and interest, and a year-wise table.
With the default inputs (₹50,000 saved, ₹5,000 a month, 7% compounded monthly, 10 years), the final balance is ₹9,65,907, of which ₹6,50,000 is your own money. The sums run in your browser, so nothing is uploaded (you can check the Network tab in DevTools), and the result is an estimate: taxes and inflation are not included.
Table of use: what changes the result
The first row uses the default inputs, and rows two to four each change one setting from it. The last row is a separate US-dollar example with a savings goal.
| Scenario | Setting | Final balance | Note |
|---|---|---|---|
| Default plan | Monthly compounding, end-of-month deposits | ₹9,65,907 | Interest ₹3,15,907; effective rate 7.23% |
| Pay at the start of the month | Contributions Made At: Start of each month | ₹9,70,955 | One extra month of interest per deposit |
| Quarterly compounding | Compounding: Quarterly | ₹9,63,581 | Effective rate 7.19% |
| Yearly compounding | Compounding: Yearly | ₹9,53,616 | Effective rate 7.00% |
| Emergency fund (USD) | $0 start, $300 a month, 4%, 3 years, goal $10,000 | $11,454 | Goal reached in year 3 |
Each month the balance is multiplied by (1 + i), where i = (1 + r ÷ n)n ÷ 12 − 1, r is the annual rate and n the compounding periods a year, and the contribution is added at the start or end of the month. The effective annual rate is (1 + r ÷ n)n − 1.

Who can use it
Anyone saving towards a goal can use it: an emergency fund, a deposit for a home, a holiday or a child's education. It also suits comparing deposit accounts that compound at different frequencies. It assumes a fixed rate and regular deposits, so it is a planning aid rather than a quote from a bank.
For related sums, the compound interest calculator and simple interest calculator show the interest side in detail, and the interest calculator covers a single deposit. Look further ahead with the retirement calculator or the investment calculator. Borrowing instead? Try the loan calculator or mortgage calculator. The percentage calculator and currency converter help with the arithmetic around it, and the calculators hub lists the rest.
Frequently asked questions (FAQs)
How does the savings calculator work?
It simulates your balance month by month. Each month the balance earns interest at the monthly rate equivalent to your annual rate and compounding frequency, and your monthly contribution is added at the start or the end of the month, as you choose. The total, the interest earned and every row of the year-wise table come from that same calculation.
What difference does compounding frequency make?
The more often interest is compounded, the more interest you earn on earlier interest. At 7% a year, monthly compounding gives an effective annual rate of 7.23%, quarterly 7.19%, half-yearly 7.12% and yearly 7.00%. With the default inputs, monthly compounding ends at ₹9,65,907 against ₹9,53,616 for yearly. Use the frequency your account states.
Should I choose start or end of month for contributions?
Choose Start of each month if the money goes in at the beginning of each period, such as on payday, and End of each month if it goes in at the close. Start-of-month deposits earn one extra month of interest each, so the balance is slightly higher: ₹9,70,955 instead of ₹9,65,907 with the default inputs.
How much should I save each month?
A common guideline, the 50/30/20 rule, puts 20% of take-home pay towards savings and debt repayment. The right amount is one you can keep up, so start where you can and raise it over time. If you enter a Savings Goal that your current plan would miss, the calculator shows the monthly amount needed to reach it within your chosen period; if the plan already gets there, it shows the year you reach it.
How large should my emergency fund be?
A common recommendation is three to six months of essential expenses, more if your income is irregular or others depend on you. Add up housing, utilities, food, insurance and minimum debt payments to find your monthly figure, multiply it by three to six, and enter the result as your Savings Goal to see the year you reach it.
What interest rate should I use?
Use the rate your account or deposit actually pays and check whether it is quoted before or after tax. Enter it as the yearly rate for the compounding option you choose. For investments with variable returns, use a cautious estimate and try several scenarios. The calculator does not include taxes or inflation.
Is it safe to enter my savings figures here?
Yes. The calculation runs in your browser, so the amounts you type are not uploaded or stored, and they disappear when you close the page. The Download PDF button builds the report in your browser too. You can verify this in the Network tab of your browser DevTools while you change the inputs.
