Simulate your retirement corpus year by year — see how long it lasts with inflation-adjusted monthly withdrawals.

The pension withdrawal simulator models how long your retirement savings will last based on monthly withdrawal amount, portfolio return, and inflation. Many retirees run out of money because they underestimate longevity or inflation. This calculator helps you find the sustainable monthly income from any corpus size.
With monthly expenses of ₹50,000 at retirement (inflation-adjusted from today), planning for 25 years at 7% post-retirement return: approximately ₹75–85 lakhs. At ₹1 lakh/month expenses: ₹1.5–1.7 crore. Use this calculator for your specific numbers.
Pension: employer-provided guaranteed monthly income (rare in private sector). Annuity: insurance product — you give insurer a lump sum, they pay monthly income for life or fixed period. NPS mandates 40% corpus be used for annuity purchase.
NPS annuity typically yields 5–6% annually on the annuity corpus — lower than most equity or even balanced fund returns. However, it is guaranteed for life. Most financial planners recommend buying minimum mandatory annuity (40%) and managing the rest as SWP for better overall returns.
Conservative: ₹40L in annuity (guaranteed ₹16,000/month) + ₹60L in balanced fund SWP (₹40,000/month at 8% sustainable). This gives ₹56,000/month total with one guaranteed component. Aggressive: entire corpus in balanced fund, SWP ₹65,000/month (sustainable at 8% return).
At 6% inflation, ₹50,000/month in 2025 has only ₹15,600 purchasing power in 2045. A fixed withdrawal loses purchasing power rapidly. Increase SWP by 5–6% annually to maintain lifestyle — this depletes corpus faster but preserves quality of life.
