Every serious investor in India has one question when it comes to retirement planning. Which offers a higher long-term pension IRR: NPS or mutual funds? The solution is more complicated than advertising brochures suggest. In addition to returns, the pension’s internal rate of return is influenced by taxes, lock-in regulations, annuity terms, and post-retirement flexibility. To help you determine what actually works for your retirement income, this article breaks down the contrast in simple terms.
After accounting for all cash flows, the Internal Rate of Return, or IRR, indicates the true yearly return on your investment. Because funds are held for decades and taken gradually, IRR becomes crucial for pension planning. Retirement income can vary by lakhs of rupees, even if the difference is only one percent. This comparison reveals a surprising difference in pension IRR that most retirement planners completely miss.
Planning to sip coconut water on a Goa beach at 60? The critical question then is not “Which fund gave the highest CAGR?” but “Which route gives the highest pension IRR?” In today’s post we decode the NPS vs. mutual fund IRR mystery with live Excel numbers, tax angles, and annuity reality checks.
1. Why “IRR” Matters More Than “Returns.”
IRR, or the genuine “pension yield” you can spend, is the single discount rate that reduces the net present value of all cash flows to zero.
CAGR just considers fund value; IRR also accounts for annuity rates, exit rules, taxes paid, and taxes saved.
Therefore, if the latter requires a low-yield annuity, an 11% CAGR mutual fund can nonetheless provide a better pension IRR than a 9% CAGR NPS.
In pension products, IRR is affected by
contribution period
market returns
tax benefits while investing
tax at withdrawal
mandatory annuity rules
2. What Is NPS and How Pension IRR Works
Tier-I, government-regulated (PFRDA), and only intended for retirees.
Auto/Active option: up to 75% equity until 50%.
The lowest expense ratio in India is approximately 0.01%.
Maturity: 40% mandatory annuity (taxable), 60% lump amount (tax-free).
Tax benefits: ₹1.5 lakh under section 80C + an additional ₹50k under section 80CCD(1B) + employer advantage under section 80CCD(2).
PFRDA oversees the National Pension System, a retirement plan supported by the government. It distributes your funds among government securities, corporate bonds, and stocks.
Important characteristics that influence IRR
Minimal fund management expenses, often less than 0.1 percent
For active investors, equity exposure is limited to 75%.
At least 40% of the corpus must be purchased in an annuity upon retirement. Tax benefits under 80CCD(1), 80CCD(1B), and 80CCD(2)
Over extended periods of time, NPS stock funds have historically produced annual returns of 10 to 12 percent; however, actual pension IRR decreases as a result of post-retirement annuity returns.

3. Mutual Funds for Retirement Planning
SEBI regulates market-linked investments, such as mutual funds. Investors usually employ equity mutual funds, index funds, and hybrid funds through SIPs for retirement.
Factors affecting pension IRR
Except with ELSS, lock-in is not required.
Total authority over the distribution of assets
No obligatory purchase of annuities
greater expense ratio (often 0.2 to 1 percent) in comparison to NPS
In India, diversified equities mutual funds have historically produced 12 to 14 percent CAGR before taxes over extended periods of time.
Historically, equity funds have made up 10–15% over a decade or more; hybrid funds have made up 8–12%.
Cost: 0.5–2%; no annuity clause or equity cap.
Withdrawal flexibility: LTCG 10% above ₹1 lakh annually; SWP at any time.
ELSS offers 80C (₹1.5 lakh); however, the lock-in period is limited to three years.
Most investors only look at headline returns and ignore withdrawal rules when comparing nps vs mutual fund pension irr. In reality pension IRR depends on annuity conversion in NPS and it depends on withdrawal flexibility in mutual funds. It is more important to understand nps vs mutual fund pension irr after retirement than pre-retirement returns.
4. Modelling Methodology (How IRR is Calculated for NPS vs Mutual Fund)
In NPS
You make monthly or annual investments.
You receive upfront tax savings.
Forty percent goes into an annuity and sixty percent can be taken out at age sixty.
Annuities normally yield an annual return of 5 to 6.5 percent.
in Mutual Funds
Investing in mutual funds using SIPs yields completely compounded returns.
You use SWP to withdraw methodically.
No coerced switch to low-yielding instruments
NPS headline returns may appear greater than actual pension IRR due to annuity drag.
Cash flow set: ₹15,000 per month for 25 years (age 30–55 for MF, 30–60 for NPS).
CAGR for gross portfolio: NPS 10%, MF 12%.
Expenses: MF 1% TER; NPS 0.01% TER.
Tax: NPS—annual savings of 80 CCD (1B) reinvested in the same NPS.
MF—an annual ₹1.5 lakh 80C already utilized (conservative).
Exit: 40% purchases a 6% annuity (post-tax 4.2%), and 60% is tax-free.
MF—the entire corpus was converted into 70% debt and 30% equity, yielding 7%; SWP was created to equal the NPS pension.
Excel XIRR on net cash-in and cash-out streams was used to solve IRR.

Historical Returns Comparison in India
On paper, NPS equity plans have produced a CAGR of about 10 to 12 percent. The CAGR for equity mutual funds has been between 12 and 14 percent.
In reality, NPS IRR frequently falls to 7 to 8 percent following annuity impact. If withdrawals are carefully scheduled, mutual fund retirement IRR often stays closer to 10 to 11 percent.
Tax Treatment and Its Impact on Real IRR
NPS tax advantages
An additional 50,000 deduction under 80CCD (1B).
Up to a certain amount, employer contributions are tax-free. 60% of withdrawals are tax-free.
Rules for mutual fund taxes
Except for ELSS, long-term capital gains are taxed beyond the exemption limit. Tax-efficient SWP can lower the yearly tax burden.
NPS tax savings greatly increase the effective IRR during accumulation for high-income salaried workers.
Liquidity, Flexibility, and Control Comparison
NPS
Tight withdrawal guidelines
Restricted freedom before retirement
Market-determined annuity rates at retirement
Mutual Funds
Complete liquidity
Adaptable withdrawals
The flexibility to alter funds, strategy, and asset allocation at any time
Risk Profile and Volatility Over the Long Term
Flexibility frequently means more to self-employed people than tax deductions.
NPS uses lifecycle funds to automatically lower volatility as people age. This limits upside while safeguarding capital. Even near retirement, mutual funds enable greater stock exposure, which can increase returns but requires self-control.
For knowledgeable investors who periodically rebalance, risk-adjusted returns frequently favor mutual funds.
Which Option Gives a Higher Pension IRR in Reality
NPS is solely based on IRR. In general, mutual funds provide larger pensions. IRR NPS provides a consistent but reduced income after retirement. However, NPS becomes competitive for salaried individuals in higher tax bands when tax savings are taken into account.
Who Should Choose NPS & Who Should Choose Mutual Funds
NPS is ideal for salaried workers who receive an employer contribution. Individuals in the 30% tax rate and investors who favor low-cost, disciplined investment. Those who feel at ease with annuity-based pensions.
Whereas a mutual fund is ideal for self-employed professionals, business owners, and investors who want complete control over their retirement income and a greater long-term internal rate of return.
| Factor | NPS Pension | Mutual Fund Retirement |
|---|---|---|
| Investment type | Government-regulated pension scheme | Market-linked investment |
| Equity exposure | Capped at 75 percent | No fixed cap |
| Lock-in period | Till age 60 | No mandatory lock-in |
| Withdrawal rule | 60 percent lump sum, 40 percent annuity | Flexible via SWP |
| Post-retirement returns | Low due to annuity | Market-linked |
| Typical pension IRR | Around 7 to 8 percent | Around 9 to 11 percent |
| Tax benefit during investment | High for salaried investors | Limited |
| Control after retirement | Limited | Full control |
| Best suited for | Conservative, salaried investors | Return-focused investors |
Smart Hybrid Strategy for Retirement
The most sensible strategy is NPS + mutual funds rather than NPS vs mutual funds. Use mutual funds for growth and flexible retirement income, and NPS primarily for stability and tax savings. Liquidity, returns, and safety are all balanced by this combination.
Final Verdict for Indian Investors
Over time, mutual funds typically beat NPS if your main objective is a larger pension IRR. NPS is a useful auxiliary tool if your objective is tax efficiency and enforced discipline. The most astute Indian retirement plans make good use of both, matching consistent pension income and long-term asset development with tax advantages.

FAQs
Q1. Is the NPS pension IRR guaranteed or market-linked?
NPS pension IRR is partly market-linked at the accumulation phase and partly fixed after retirement. NPS corpus grows based on equity market and debt market performance, when at least 40 percent of the corpus must be used to buy an annuity. As annuity returns are relatively low and fixed, the overall pension irr of NPS becomes more stable, but it is lower compared to full market-linked options.
Q2. Can mutual funds provide regular pension-like income after retirement?
Yes, mutual funds can provide pension like income through a systematic withdrawal plan. In a MF SWP the investor decides on how much and when to withdraw and how long the corpus should last. This flexibility results in a higher effective pension IRR compared to NPS especially when tax efficient withdrawals are planned.
