How this calculation works
This models a cumulative deposit, where interest remains invested. It does not model a monthly interest-payout deposit. Select the compounding frequency specified by the provider.
Maturity = deposit × (1 + rate ÷ 100 ÷ m)^(m × years)A worked example
₹1,00,000 at 7%, compounded quarterly for 5 years, grows to approximately ₹1,41,477.82.
Good to know
A planning estimate. Actual products may use different payment dates, fees, tax treatment or rounding. Rates entered here are assumptions, not offers.
Cumulative and interest-payout deposits are different
In a cumulative deposit, interest remains in the account and can participate in later compounding. An interest-payout deposit sends interest to you during the term, so that money does not automatically keep compounding inside the original deposit.
This calculator models the cumulative version. To compare a payout product, account for when each payment arrives and what happens to it afterward. Merely comparing a maturity balance with a payout product’s final principal overlooks the cash already received.
The headline rate does not tell the whole story
Using the same nominal 7% annual rate on ₹1,00,000 for five years, yearly compounding gives about ₹1,40,255, while quarterly compounding gives about ₹1,41,478. The rate has not changed; the timing of capitalization has.
Those figures are illustrations from the formula, not current bank offers. A real comparison also needs matching tenure, eligibility, payout terms, premature-withdrawal conditions and tax treatment.
Gross interest is not the same as take-home interest
The maturity figure is before any tax or deductions. Whether interest is taxable, how withholding is applied and what rate ultimately applies depend on the relevant rules and your circumstances. This generic growth calculation does not resolve those questions.
Some deposit terms use exact calendar dates, provider-specific rounding or different treatment of partial periods. Use the bank’s official maturity quotation for the final contract amount.
A few questions, answered
Does it use a live bank interest rate?
No. Enter the rate and compounding frequency from the product you are considering.
Is the result guaranteed?
It is a mathematical estimate under the entered assumptions. The product’s actual terms and the provider’s obligations determine what is payable.
