What is the CAGR Calculator?
The CAGR (Compound Annual Growth Rate) Calculator helps you measure the true annualised growth rate of any investment over a period of time, smoothing out the volatility of year-to-year returns into a single, comparable percentage. Whether you are evaluating a mutual fund, tracking the growth of your fixed deposit corpus, or benchmarking your equity portfolio against the Nifty 50, CAGR gives you an apples-to-apples number that a simple absolute return percentage cannot.
For Indian investors, CAGR is especially important because of the sheer diversity of instruments available — from EPFO-linked PF accounts (currently earning 8.25% for FY 2024-25) and PPF (7.1% per annum) to ELSS mutual funds, direct equity, REITs, and Sovereign Gold Bonds. Marketing materials often quote "absolute returns" over multi-year periods, which can be misleading. A fund that claims 120% returns over 6 years sounds impressive, but its CAGR is only about 14% — barely ahead of a well-chosen large-cap index fund after LTCG tax.
SEBI now mandates that mutual fund performance be disclosed as CAGR for periods beyond one year, making this metric the standard language of wealth creation in India. Understanding and computing CAGR correctly lets you cut through the noise, compare your SIP with NPS Tier-I returns, or decide whether your real-estate investment has actually beaten inflation (CPI averaged ~5.4% in FY 2025-26).
How does it work?
The core CAGR formula is straightforward: CAGR = (Ending Value / Beginning Value)^(1/n) – 1, where n is the number of years. For example, if you invested ₹1,00,000 and it grew to ₹2,00,000 over 5 years, the CAGR is (2,00,000 / 1,00,000)^(1/5) – 1 = 2^0.2 – 1 ≈ 14.87% per annum. This single number tells you the constant annual rate at which your money would have had to grow to reach that ending value — it does not tell you what happened in between, but it gives you the best single-figure summary of long-term performance.
The three inputs to the calculator are: Beginning Value (your initial investment or the value at the start of the measurement period), Ending Value (the current or final corpus value), and Time Period in years (decimals are accepted — e.g., 2.5 years for a 30-month investment). For lump-sum investments like a fixed deposit, an NPS Tier-II allocation, or a direct equity purchase, these three numbers are all you need. It is important to use the actual invested amount as the beginning value, not including any top-ups made along the way, as those would require an XIRR calculation instead of simple CAGR.
CAGR differs from XIRR (Extended Internal Rate of Return), which handles irregular or periodic cash flows such as monthly SIPs or systematic withdrawals. If you are measuring a monthly SIP in a mutual fund, use the XIRR calculator. CAGR is ideal for lump-sum point-to-point comparisons: comparing your LIC endowment policy maturity against what a ELSS fund would have returned over the same period, or checking whether your plot of land bought in 2015 has outpaced the Sensex.
Worked example
Consider Priya, 35, a software engineer in Pune earning ₹18 LPA. In April 2019, she invested a lump sum of ₹5,00,000 in a Nifty 50 Index Fund (direct plan). By March 2025 — exactly 6 years later — her investment had grown to ₹11,40,000. Plugging into the CAGR formula: (11,40,000 / 5,00,000)^(1/6) – 1 = (2.28)^(0.1667) – 1 ≈ 14.74% CAGR. She compares this against her PPF contributions earning 7.1% and her employer's NPS contribution (Tier-I, equity allocation) which showed a CAGR of 12.3% over the same period. The index fund clearly outperformed on a pre-tax basis.
However, Priya's ₹6,40,000 gain from the equity fund is subject to Long-Term Capital Gains (LTCG) tax at 12.5% (Budget 2024 rate) on gains exceeding ₹1,25,000 in a financial year. Her taxable LTCG is approximately ₹6,40,000 – ₹1,25,000 = ₹5,15,000, resulting in a tax of ₹64,375. Her post-tax corpus is approximately ₹10,75,625, giving a post-tax CAGR of roughly 13.59%. Even after tax, the index fund beat PPF by over 6 percentage points annually — a powerful illustration of why CAGR comparisons, done correctly with tax adjustments, drive better long-term financial decisions.
When to use this calculator
- 1Evaluating mutual fund performance: When a fund house advertises '150% returns in 7 years,' use CAGR to convert that to ~14% per annum and benchmark it against the category average or Nifty 500 TRI.
- 2Comparing investment options at milestones: Before choosing between locking money in a 5-year bank FD at 7.25% versus a debt mutual fund, calculate the post-tax CAGR of each based on your income tax slab (30% slab investors benefit from indexation on debt funds held over 3 years, though rules changed post-April 2023).
- 3Measuring real-estate appreciation: If you bought a flat in Hyderabad for ₹45 lakh in 2015 and it is worth ₹90 lakh today (2025), CAGR = (90/45)^(1/10) – 1 ≈ 7.18% — compare this against inflation and equity to assess whether property was your best option.
- 4Tracking your PF or NPS corpus growth: Cross-check whether your EPFO passbook balance is growing at the declared interest rate (8.25% for FY 2024-25) by computing CAGR between two annual statements.
- 5Setting realistic retirement goals: If you need ₹3 crore in 20 years and have ₹20 lakh today, the required CAGR is (3,00,00,000 / 20,00,000)^(1/20) – 1 ≈ 14.1% — helping you decide whether your current asset allocation is aggressive enough.
Common mistakes to avoid
- ✕Confusing absolute returns with CAGR: A ULIP or LIC policy that doubled your money in 10 years has a CAGR of only 7.2%, which is below the current PPF rate. Indians frequently accept such products because the agent presents the absolute doubling as impressive.
- ✕Ignoring inflation when interpreting CAGR: A real-estate CAGR of 8% sounds good until you subtract India's average CPI inflation of ~5.5%, leaving a real return of only 2.5% — often lower than a liquid mutual fund after tax.
- ✕Comparing CAGR across different time periods: A fund's 1-year return of 40% (driven by a bull market) versus its 10-year CAGR of 12% are not comparable. Indians often chase recent performance without understanding that short-period returns distort the picture.
- ✕Using CAGR for SIP returns instead of XIRR: If you have been investing ₹10,000 per month in a mutual fund, calculating CAGR on (total invested vs. current value) gives a misleadingly low number. SIP performance must be evaluated with XIRR, which accounts for the timing of each installment.
- ✕Not accounting for charges and taxes: Many investors compute CAGR on gross NAV growth without deducting the expense ratio (up to 2.25% for regular plans under SEBI limits), exit loads, STT, and applicable LTCG/STCG tax — all of which reduce the effective CAGR materially.
Frequently asked questions
- What is a good CAGR for mutual funds in India?
- As a benchmark, the Nifty 50 TRI has delivered approximately 13-14% CAGR over the past 20 years. Large-cap funds are expected to match or slightly beat this; mid-cap and small-cap funds have historically delivered 15-18% CAGR over long periods but with significantly higher volatility. Debt funds typically deliver 6-8% CAGR depending on duration. A 'good' CAGR depends on your asset class, risk tolerance, and investment horizon — always compare against the relevant benchmark index, not in isolation.
- Is CAGR or XIRR better for evaluating SIP investments?
- XIRR is always better for SIP evaluation. CAGR assumes a single lump-sum investment at the start and a single withdrawal at the end. A SIP involves multiple cash flows at different points in time, so CAGR will understate the actual return. For example, if you invested ₹5,000/month for 10 years (total ₹6 lakh) and the corpus is ₹12 lakh, the CAGR on (6,00,000 to 12,00,000 over 10 years) is 7.2%, but the actual XIRR could be 13-14% because most of the money was invested much later than the start date.
- How does CAGR relate to PPF and EPF interest rates?
- PPF and EPF interest rates are declared annually and are effectively the CAGR of those instruments if you make a single lump-sum deposit and withdraw at maturity without top-ups. PPF currently offers 7.1% per annum (Q1 FY 2026-27, unchanged) and EPF offers 8.25% for FY 2024-25. These are guaranteed, tax-free (for EPF contributions within ₹2.5 lakh/year limit) returns. When comparing equity mutual fund CAGRs against PPF/EPF, remember to adjust equity returns for LTCG tax (12.5% above ₹1.25 lakh) to make a fair post-tax comparison.
- Can CAGR be negative, and what does that mean?
- Yes. If your ending value is less than your beginning value, the CAGR will be negative, indicating capital erosion. For example, if you invested ₹1,00,000 in a mid-cap fund in January 2018 and it was worth ₹85,000 in January 2020 (2 years), the CAGR = (85,000/1,00,000)^(0.5) – 1 = -5.9% per annum. Negative CAGR is especially relevant when evaluating thematic funds, sector funds, or direct equity picks that underperformed. It is also a reminder to consider your investment horizon — many equity instruments with negative 3-year CAGRs have delivered positive 10-year CAGRs.
- How is CAGR used in NPS performance evaluation?
- The Pension Fund Regulatory and Development Authority (PFRDA) publishes scheme-wise NAV histories, and NPS fund returns are typically reported as CAGR for 1, 3, 5, and since-inception periods. For NPS Tier-I Equity (E) schemes, leading fund managers like SBI Pension, HDFC Pension, and UTI Retirement have delivered 13-16% CAGR since inception (circa 2009). Since NPS withdrawals (up to 60% of corpus at retirement) are now fully tax-free under Section 10(12A), and annuity purchases are tax-deferred, the effective post-tax CAGR of NPS is often higher than equivalent mutual fund investments for taxpayers in the 30% slab.
