A close estimate using the standard RD formula. Confirm the exact maturity value with your bank or post office before you rely on it.
Your RD maturity in four steps.
Enter your monthly deposit, set the rate and tenure, and read the maturity value. The result updates as you type, split into what you pay in and the interest it earns.
Enter your monthly deposit
Type the fixed amount you plan to pay in every month. Pick your currency so the figures read the way you expect.
Set the interest rate
Add the annual interest rate your bank or post office offers on the RD. Tap a quick rate or type your own.
Choose the tenure
Pick how long you will keep paying in, in months or years. Longer tenures give interest more time to compound.
Read the maturity value
See what you will have at the end, split into what you paid in and the interest earned, with a year-by-year view.
How RD interest is worked out.
Recurring deposit interest compounds every quarter. Each monthly deposit earns from the month you pay it in, so earlier deposits compound for longer.
The formula
The standard bank formula, with quarterly compounding.
M = P × [(1 + i)^n - 1] ÷ [1 - (1 + i)^(-1/3)]
i = rate ÷ 400
n = months ÷ 3
P is the monthly deposit, i is the quarterly rate, and n is the number of quarters.
A worked example
₹5,000 a month for 3 years at 7% a year.
Invested = 5,000 × 36 = ₹1,80,000
Maturity ≈ ₹2,00,700
Interest ≈ ₹20,700
The interest builds up faster towards the end, as more of your deposits have had time to compound.
RD, FD or SIP?
They all help you build savings, but they work differently. Here is how a recurring deposit compares with a fixed deposit and a monthly SIP.
Returns: Fixed, assured
Pay in a set amount every month for a fixed term. The rate is locked when you open it, so the maturity value is known in advance. Good for steady, low risk saving.
Returns: Fixed, assured
Park a single amount for a term at a fixed rate. Same assured family as an RD, but you need the whole sum upfront rather than building it up month by month.
Returns: Market linked
Like an RD in rhythm, but the money goes into mutual funds. Returns are not guaranteed and can rise or fall, with the trade off of higher potential growth over the long run.
Savings products, built properly.
A calculator like this is the easy part. Running deposits, lending and savings products for real customers takes accurate interest engines, statements that reconcile, secure onboarding and dashboards your team can trust. That is the kind of fintech and banking software we build at Techliphant, shaped around how your business actually works.

Common RD questions.
A recurring deposit is a savings product from a bank or post office where you pay in a fixed amount every month for a chosen term. It earns interest at a rate that is fixed when you open the account, and at the end of the term you get back everything you paid in plus the interest. It suits people who want to save a little each month with an assured return.
An RD calculator is a free tool that works out what your recurring deposit will be worth at maturity. You enter the monthly deposit, the interest rate and the tenure, and it shows the maturity value, the total you will have paid in, and the interest you will earn, without you having to do the compounding by hand.
The standard formula uses quarterly compounding: maturity = P x [(1 + i)^n - 1] / [1 - (1 + i)^(-1/3)], where P is the monthly deposit, i is the annual rate divided by 400, and n is the number of quarters, which is the tenure in months divided by three. This calculator applies that formula for you, so you just read off the result.
Most banks compound RD interest every quarter, which is what this calculator assumes. Each monthly deposit starts earning from the month you pay it in, and the interest itself earns interest at each quarter end. Because earlier deposits compound for longer, the interest builds up faster towards the end of the term.
With a fixed deposit you invest a single lump sum once and leave it for the term. With a recurring deposit you pay in a fixed amount every month and build the balance up over time. Both offer a fixed, assured return, so an RD is the better fit when you want to save from your monthly income rather than commit a large sum upfront.
Both involve investing a fixed amount every month, but an RD is a bank deposit with a guaranteed rate, while a SIP puts your money into mutual funds, where returns are market linked and not assured. An RD gives certainty, a SIP offers the chance of higher returns over the long run with more ups and downs along the way.
It varies by bank, tenure and from time to time, and senior citizens usually get a little extra. Rates often sit somewhere around the mid to high single digits, but you should always check the current rate with your own bank or post office before relying on a figure. Enter that exact rate here for an accurate maturity value.
Yes. Interest from a recurring deposit is added to your income and taxed at your slab rate. Banks also deduct TDS once the interest crosses the threshold set by the tax rules. This calculator shows the interest before any tax, so your take home may be a little lower depending on your situation.
Usually yes, but premature withdrawal typically means a lower interest rate and sometimes a small penalty, so you earn less than if you had held it to maturity. Some banks also let you take a loan or overdraft against the RD instead of breaking it. Check your bank terms before you open one.
Bank RDs generally run from six months up to ten years, in multiples of three months, while post office RDs have their own fixed term. This calculator lets you set any tenure in months or years so you can model whatever your provider offers.
Yes on both. It is free, there is no sign-up, and it runs entirely in your browser. Nothing you type is sent anywhere or saved, so your numbers stay on your own device.
They are a close estimate using the standard RD formula. Your bank may round differently, credit interest on a slightly different schedule, or apply a special rate, so the final maturity value can differ by a small amount. Treat this as a planning guide and confirm the exact figure with your provider.
