Retirement planning is about converting today’s savings and contributions into future income that sustains your lifestyle. This Retirement Calculator projects the value of your current savings plus periodic contributions by your selected retirement age using an assumed rate of return. It’s intended to help you determine if you are saving enough, and to show how return assumptions and contribution levels influence your retirement corpus.

This tool models the compounded growth of a lump-sum and a series of monthly contributions until your chosen retirement age. It can work in two common modes: project the corpus you’ll have given current inputs, or calculate the monthly savings required to reach a target corpus by retirement. The calculator uses deterministic compounding based on an expected annual return converted to a monthly rate.
The calculator takes the expected annual return and converts it to an effective monthly rate. It compounds any existing savings for the total number of months until retirement and also compounds each monthly contribution from its deposit date to retirement. The sum of the future value of the lump-sum and the future value of the annuity (monthly contributions) gives an estimated retirement corpus.
This projection assumes constant monthly contributions and a steady average return; it does not model market volatility or the tax treatment of different accounts, which can materially change outcomes.
FV = PV × (1 + r)^n + P × (((1 + r)^n − 1) / r) where PV is current savings, P is monthly contribution, r is monthly rate, and n is number of months until retirement.
The first term compounds an existing lump sum to the retirement date. The second term calculates the future value of a series of equal monthly contributions (an ordinary annuity). Converting annual return to a monthly rate and using months as the time unit ensures contributions are compounded correctly. Small changes in return or time horizon compound into large differences over decades.
Example: Age 30, retirement at 60, current savings Rs. 5,00,000, monthly investment Rs. 5,000, expected annual return 10%. Convert 10% to a monthly rate (~0.7974% per month), compound the lump-sum and each monthly contribution for 360 months, and sum them to estimate the corpus at retirement. This number tells you whether your current saving plan will likely meet your retirement needs.
Compare results with the FIRE calculator to translate corpus into withdrawal targets, use SIP to design contribution strategies, and SWP for post-retirement withdrawal planning.
This calculator provides deterministic estimates. For a comprehensive plan, layer Monte Carlo or historical-scenario analysis, consider tax-efficient product selection (tax-advantaged accounts, annuities), and prepare for varying spending patterns in retirement.
This retirement calculator projects your savings into the future by compounding current savings and monthly investments at the expected annual return until your retirement age, producing an estimated retirement corpus and a basic annual income estimate.
The projection combines two parts: (1) future value of current savings compounded at expected return, and (2) future value of an annuity representing monthly investments compounded monthly. These sums produce the estimated retirement corpus.
