The National Pension System (NPS) is a voluntary, market-linked retirement savings scheme run by the Indian government, investing in a mix of equity, corporate bonds, and government securities with no fixed return. At retirement (typically age 60), at least 40% of the corpus must be used to purchase an annuity providing a monthly pension, while up to 60% can be withdrawn tax-free as a lump sum. This calculator lets you input your own assumed return and annuity conversion rate so you can adjust for real market conditions.

How the Corpus and Pension Are Calculated
This calculator assumes your monthly contribution compounds monthly until retirement (a future-value-of-an-annuity calculation) to estimate the total corpus. That corpus is then split 60% lump sum and 40% annuity purchase corpus. The estimated monthly pension multiplies the annuity corpus by the assumed annuity rate to get an annual figure, then divides by 12. Actual returns can vary significantly depending on your chosen fund allocation (equity, corporate debt, government securities).
Frequently asked questions
How do I choose an expected return rate?
NPS has no guaranteed return since it is market-linked. This calculator's default (10% p.a.) is an illustrative assumption β adjust it to match your own asset allocation (Equity/E, Corporate bonds/C, Government securities/G).
Why must 40% be converted into an annuity?
This rule ensures a stable post-retirement income: current regulations require at least 40% of the corpus to purchase an annuity plan from a pension fund provider, while up to 60% can be withdrawn tax-free as a lump sum.
Where do I find the actual annuity rate?
The annuity rate depends on the insurer (annuity service provider) and product you choose at retirement. This calculator's default (6%) is illustrative β compare quotes from multiple providers before purchasing.
