What is Retirement Planner Calculator and How to Use It
A retirement planner calculator helps you estimate how much money you need to accumulate before you stop working, and how much you need to invest every month to get there. In India, where inflation has historically averaged 5–6%, planning for retirement without accounting for rising costs can leave you significantly short. This retirement corpus calculator adjusts your current monthly expenses for inflation over your working years and tells you the exact corpus you need at retirement.
Start by entering your current age and the age at which you plan to retire. Then enter your current monthly expenses, the expected inflation rate, and the annual return you expect from your investments. The calculator instantly shows your inflation-adjusted retirement corpus, the monthly SIP required to reach it, and a year-by-year accumulation table. If you are wondering how much to save for retirement in India, this tool gives you a concrete, personalised answer.
A key insight: the gap between your expected return and inflation (called the real return) is what drives the corpus calculation. A higher real return means you need a smaller corpus. This is why equity investments, which historically deliver 10–14% annually in India, are preferred for long-term retirement planning over fixed deposits or PPF alone.
The Formula Behind Retirement Planning
The corpus formula assumes a perpetuity model: your corpus earns returns that cover your inflation-adjusted expenses indefinitely. The SIP back-calculation uses the standard SIP future-value formula in reverse to find the monthly investment needed.
