Start from what you spend a month today. See the money you need on the day you retire to keep spending that, rising with inflation, and the monthly SIP that builds it.
Enough to spend ₹2.15 lakh a month from the start, the same as ₹50,000 today, rising with inflation every year for 25 years.
The SIP is paid at the start of every month at a steady return; real returns rise and fall from year to year, and the figures are before tax. Try the step-up SIP calculator for a SIP that rises with your income, or the SWP calculator for withdrawals from a corpus you already have.
