How it works
- Enter the deposit amount, the annual profit rate, and the tenure in years.
- Choose how profit is worked out: monthly, quarterly, or annual compounding, or simple profit paid at maturity.
- Enter the withholding-tax rate you want applied to the profit, or leave it at 0. You see the maturity amount, the profit before tax, the tax, and the profit after tax.
No bank's actual rate is used anywhere on this page. Banks quote different rates for different tenures and amounts, and rates change — always enter the rate from the bank's current offer, and read its terms.
Formula
Compounded: Maturity amount = Deposit × (1 + annual rate ÷ periods per year)periods per year × years
Simple (at maturity): Maturity amount = Deposit × (1 + annual rate × years)
Profit = Maturity amount − Deposit. Tax = Profit × withholding-tax %. Profit after tax = Profit − Tax.
Worked example
Example: Rs 500,000 at 12% a year for 3 years, compounded quarterly, grows to Rs 712,880.44. The profit is Rs 212,880.44. At a 15% withholding-tax rate entered by the user, the tax is Rs 31,932.07 and the profit after tax is Rs 180,948.37. The same deposit with simple profit paid at maturity would reach Rs 680,000, a profit of Rs 180,000 before tax.
Frequently asked questions
What is the difference between compounding and simple profit?
With compounding, profit is added to the balance and later profit is worked out on the larger amount, so it grows faster. With simple profit, profit is worked out on the original deposit only, for the whole tenure.
Which compounding option should I choose?
Choose the one that matches the bank's offer: how often it adds profit to the account. If the bank pays profit out instead of adding it, use the simple profit option, paid at maturity.
Is the withholding tax rate the real tax rate?
No. The tax field is your input, defaulting to 0. Tax rules depend on the depositor and the current law, so enter the rate that applies to you, or 0 to see the profit before tax.
Why is the maturity amount higher with monthly compounding?
Because profit is added more often, so each later period earns profit on a slightly larger balance. At the same annual rate, monthly compounding gives a little more than quarterly, which gives a little more than annual.
Does the calculator know any bank's rate?
No. Every rate on this page is entered by you. No bank, product, or rate is named, and nothing here is an offer from any bank.
What if I withdraw the deposit early?
This calculator assumes the deposit is held for the full tenure you enter. Early withdrawal usually earns less profit or carries a penalty, and neither is included here, so check the bank's early-withdrawal terms before you rely on the maturity figure.

Important — please read
Results are estimates from the rate, tenure, and tax rate you enter. No bank's actual rate is stated or implied, and the tax rate is your input, not a statement of current tax law. Real deposits may have minimum amounts, early-withdrawal penalties, and different profit-payment terms. Confirm the offer and the tax treatment with the bank.
