About this retirement calculator
Retirement planning is about working out how much money you need to stop working and still maintain your lifestyle. The two big variables are how long your money must last and how prices rise over time.
This calculator inflates your current monthly expenses to your retirement age, then works out the corpus needed to fund those expenses through your life expectancy, assuming your investments earn a steady return after retirement. It reports the total corpus needed and your monthly expense at retirement.
The result is a target, not a guarantee. It ignores taxes, medical costs and lifestyle changes. It also assumes you invest the corpus to earn the stated return throughout retirement.
Use it to set a savings target and then work backwards to a monthly investment using the SIP calculator. Starting early dramatically reduces the monthly amount needed. Review your plan as your income and goals change, and consult a financial adviser.
