An equal annual amount withdrawn from a starting corpus while it earns a return, designed to exhaust the corpus over a fixed period. Formula: PMT = P × r ÷ (1 − (1+r)^−n) for ordinary annuity.

Enter retirement corpus, expected return and years in retirement. The calculator shows sustainable equal annual income if returns match assumptions — useful alongside NPS/SWP planning.

SWP redeems mutual fund units; payout varies if you fix rupee withdrawal and returns fluctuate. This calculator assumes fixed return and equal annual payouts — a deterministic baseline.

Conservative portfolios often use 6–8% nominal. Higher withdrawal rates or lower returns increase risk of corpus depletion before the planned horizon.

Life insurers sell annuities (immediate/deferred) regulated by IRDAI. They may include mortality credits and guarantees. This tool is illustrative math only, not a quote from any insurer.

Actual corpus may deplete faster. Build buffer, use lower return assumptions, or combine with safe fixed-income floors (SCSS, PMVVY where eligible).

₹1 crore at 8% over 25 years → annual payout ≈ ₹9,36,788, exhausting corpus in year 25 if returns match 8%.

Monthly pension depends on the annuity rate you assume and payout frequency. Enter corpus and expected payout rate to see an illustrative monthly amount. Actual NPS/insurance annuity quotes vary by age, spouse cover and insurer — this is not a quote.

Pension/annuity income is generally taxable as per your income-tax slab when received, subject to the product and regime rules that apply to you. This calculator shows gross illustrative payout only and does not compute tax.
