How the Retirement (Expense) calculator works
This calculator starts from what you spend today. It inflates your monthly expenses to your retirement age - optionally reduced, since some costs fall after you stop working - and estimates the corpus needed to keep paying those expenses, still rising with inflation, through retirement.
It then credits the future value of savings you already have and any lump-sum benefits you expect at retirement, such as PF and gratuity, and tells you the monthly investment needed for the rest.
Worked example
A 30-year-old spending ₹40,000 a month, retiring at 60 and planning to 85 (6% inflation, 10% lower expenses after retirement, 12% return while working and 8% after), will need about ₹2,06,766 a month at 60 and a corpus of roughly ₹4.96 crore. After ₹5 lakh of existing savings (worth about ₹1.5 crore by then) and ₹20 lakh of expected retirement benefits, a monthly investment of about ₹9,239 covers the rest.
Things to keep in mind
- This calculator keeps inflation running through retirement, which gives a more conservative (larger) corpus than methods that freeze expenses at retirement.
- Enter only savings earmarked for retirement - not your emergency fund or money for other goals.
- Review your plan whenever your income, expenses or goals change.

Frequently asked questions
Why reduce expenses after retirement?
Some costs - commuting, work clothes, EMIs, children's expenses - often fall. Medical costs may rise, so keep the reduction modest.
What counts as retirement benefits?
Lump sums you expect at retirement, such as EPF, gratuity, superannuation or maturing insurance policies.
Is this different from the via-target calculator?
Yes. This one derives your target from expenses; the via-target calculator starts from a retirement amount you already have in mind.
