Each monthly contribution is compounded from the month it is invested until retirement, using your expected annual rate of return. Since contributions made earlier in your career have more time to compound, the maturity amount is the sum of all these individually-compounded contributions.

NPS returns depend on your chosen asset allocation between equity, corporate bonds, and government securities. Historically, NPS equity-heavy portfolios have returned around 9-12% annually over the long term, while conservative portfolios return closer to 7-9%.

NPS contributions qualify for deduction under Section 80CCD(1) within the overall 80C limit of ₹1.5 lakh, plus an additional ₹50,000 deduction under Section 80CCD(1B), making NPS one of the most tax-efficient retirement instruments in India.

No, NPS rules require you to use at least 40% of the accumulated corpus to purchase an annuity that provides a regular pension. The remaining amount (up to 60%) can be withdrawn as a lump sum, and this portion is tax-free.

Contributing consistently every month rather than in irregular lump sums maximizes the compounding benefit, since each monthly contribution starts earning returns from the month it is invested. Starting contributions early in your career has the largest impact on final corpus size.
