A retirement calculator projects how much your savings will grow to by the
time you retire, combining your current savings and ongoing monthly
contributions with an expected rate of return. It's a quick way to see if
you're on track for the retirement you want.

Formula
Retirement Corpus = FV(Current Savings) + FV(Monthly Contributions)
Current savings and each monthly contribution are compounded forward to your
retirement age using the expected monthly rate of return, then summed to get
your total projected corpus.
Example
If Current Age = 30, Retirement Age = 60, Current Savings = 5,00,000, Monthly Contribution = 15,000, Expected Return = 10%:
Retirement Corpus ≈ 4,41,09,000
Out of that, only about 59,00,000 comes from money actually contributed —
the rest, roughly 3,82,00,000, comes purely from investment growth over 30 years.
How Retirement Connects to Your Other Calculators
Your retirement corpus rarely comes from one source, so it helps to see how the
other calculators on this site feed into the same long-term picture.
SIP Calculator — if part of your retirement plan is market-linked mutual fund investing, use this to model that portion separately at a different expected return.
PPF Calculator and FD / RD Calculator — model the safer, fixed-return portion of your retirement savings alongside your market-linked contributions.
Mortgage Calculator — knowing your fixed mortgage payment helps you work out how much you can realistically set aside each month for retirement.
CAGR Calculator — check the actual compound annual growth rate of your existing investments to see if your assumed return rate here is realistic.

Frequently Asked Questions
A retirement calculator estimates the total corpus you'll have by your target retirement age, based on your current savings, monthly contributions, years until retirement, and expected annual rate of return. It helps you see whether your current savings plan is on track to meet your retirement goals.
There's no single answer since it depends on your target retirement corpus, current age, expected returns, and desired lifestyle after retiring. A common approach is to work backward from a target corpus and use a calculator like this to see what monthly contribution gets you there.
No, this calculator projects a nominal future value based on the return rate you enter, without adjusting for inflation. To get a more realistic picture of purchasing power, consider using a lower, inflation-adjusted return rate rather than the raw expected return.
This depends on how your retirement savings are invested; equity-heavy portfolios have historically returned more over long periods than fixed-income options, but also carry more short-term volatility. It's generally safer to plan with a conservative, realistic rate rather than an optimistic one.
Starting later means your contributions have fewer years to compound, so you typically need to save a larger amount each month to reach the same target corpus compared to starting earlier. This is why the number of years until retirement has such a large effect on the final result.
Yes, this calculator lets you enter your current retirement savings separately from your ongoing monthly contribution, so both amounts grow at the expected rate of return until your target retirement age.
