- Corpus Growth: Each year’s contribution grows with both compounding and annual step-up percentage.
- Nominal Corpus: Future Value = Σ [Monthly Contribution × (1 + step-up)^n × compound factor]
- Permitted Lumpsum: Corpus × (Lumpsum% ÷ 100)
- Annuity: Remaining Corpus × (Annuity Return ÷ 12) = Monthly Pension
- Real Corpus: Nominal ÷ (1 + Inflation)^years

The National Pension System (NPS) is one of India’s most reliable and regulated retirement investment plans. However, unlike static calculators that assume a fixed monthly investment, in reality, most investors increase their contribution every year, either due to salary increments or improved savings discipline.
That’s where FinMinutes’ NPS Calculator with Increasing Contribution comes in, it provides a more realistic projection of your future NPS corpus, lumpsum eligibility, and pension.
What is an NPS Calculator with Increasing Contribution?

A step-up or NPS calculator with increasing contribution allows users to estimate their retirement corpus by assuming that monthly contributions grow by a fixed percentage every year, for example, a 5% yearly increase in investment.
This mimics how salaried professionals naturally raise their NPS investments as their income grows, producing a much closer projection of actual returns. FinMinutes’ tool calculates:
- 📈 Total corpus at retirement
- 💰 Tax-free lumpsum withdrawal (up to 60%)
- 🏦 Mandatory annuity corpus (at least 40%)
- 🧓 Estimated monthly pension
- 💵 Real (inflation-adjusted) corpus value
- 📊 Nominal and real CAGR
All these metrics are computed using the same compounding formula that NPS fund managers apply to actual contributions.
How Does Our Calculator Work?
Our NPS calculator with increasing contribution considers both monthly investments and annual step-up percentage, alongside your chosen:
- Years until retirement
- Expected annual return (gross)
- NPS expense ratio (TER)
- Inflation rate
- Lumpsum withdrawal percentage
- Assumed annuity yield
It then computes month-by-month compounding using the following formulas:
Formula & Methodology
1. Future Value (FV) of Contributions


Example Calculation
Let’s assume:
- Monthly investment: ₹5,000
- Annual increase: 5%
- Years until retirement: 30
- Expected return (gross): 10% p.a.
- Expense ratio: 0.10%
- Inflation: 6%
- Lumpsum: 60%
- Annuity yield: 6%
Results:
| Parameter | Estimated Value |
|---|---|
| Total Invested | ₹34.8 lakh |
| Nominal Corpus | ₹98.5 lakh |
| Lumpsum Withdrawal | ₹59.1 lakh |
| Annuity Corpus | ₹39.4 lakh |
| Estimated Monthly Pension | ₹19,700/month |
| Real (Inflation-Adjusted) Corpus | ₹17.0 lakh |
| Nominal CAGR | 10.07% |
| Real CAGR | 3.6% |

Expected Return from NPS: Realistic Insights
Historically, NPS equity and government debt allocations have delivered 8%–10% annualized returns over the past decade (as per PFRDA and NPSTRUST data). Actual returns depend on:
- Asset allocation (E, C, G tiers)
- Fund manager performance
- TER (total expense ratio)
- Market volatility
What’s a Reasonable Expectation?
- Equity-heavy Tier I NPS: 10–11% p.a. long-term
- Corporate + Govt mix: 8–9% p.a.
- Conservative mix: 7–8% p.a.
With a TER under 0.1% for most NPS funds, your net compounding rate remains among the highest across regulated retirement plans.
What About Annuity Returns?
Upon retirement, at least 40% of your NPS corpus must be invested in an annuity plan. As of 2024-25, annuity returns in India typically range between 5.5% and 7% per annum, depending on:
- Annuity provider (LIC, SBI Life, HDFC Life, etc.)
- Option selected (lifetime pension, joint life, return of purchase price, etc.)
Our calculator allows you to modify the assumed annuity yield to estimate pension accurately.
