Endowment Policies vs Mutual Funds: Calculating Real IRR (CAGR)

How to calculate the true Internal Rate of Return (IRR) on traditional insurance policies and compare them against Term Insurance + SIP.

01

Overview & Core Concept

Traditional life insurance endowment and money-back policies combine life cover with an investment component. Unfortunately, blending the two produces sub-par outcomes: inadequate life cover (often only 10x annual premium) and low single-digit annualized returns.

Separating insurance from investments (buying pure Term Insurance for protection and investing the difference in equity/PPF) creates vastly superior life cover and a dramatically larger wealth corpus.

02

Step-by-Step: How to Use the Calculator

1

Enter Annual Policy Premium and Paying Term

Input your yearly premium payment and the premium paying duration (e.g., 15 or 20 years).

2

Input Maturity Year and Guaranteed Maturity Sum

Specify the policy maturity year and total expected maturity payout quoted by your insurance brochure.

3

Review Real Annualized IRR

The calculator runs an internal cashflow solver to compute the exact CAGR return of the policy.

4

Compare with Pure Term + SIP Alternative

See what happens if you spend ₹10,000 on a ₹1 Crore term plan and invest the remaining premium into an index SIP.

03

Mathematical Formula & Derivation

Analytical Formula Expression
0=∑t=0NCt(1+IRR)t0 = \sum_{t=0}^{N} \frac{C_t}{(1 + \text{IRR})^t}

Practical Case Study & Real Numbers

Case Study: ₹1,00,000 Annual Premium for 20 Years

Scenario: A 30-year-old pays ₹1,00,000/year for 20 years into an endowment plan with ₹10L life cover and promised ₹42L maturity.
Numerical Breakdown
Total paid = ₹20,00,000. Maturity = ₹42,00,000. The calculated IRR is ~5.4% p.a. If instead they bought a ₹1 Crore Term Cover for ₹12,000/year and invested the remaining ₹88,000/year into an index fund at 12% CAGR:
Key Takeaway: The Term + SIP route yields ~₹71.3 Lakhs at Year 20 with 10x higher life cover (₹1 Crore vs ₹10 Lakhs). The opportunity loss of the endowment policy is ~₹29.3 Lakhs!

Pro Tips & Critical Pitfalls

Expert Pro Tips
  • The "Buy Term and Invest the Rest" (BTIR) principle is the gold standard of personal financial planning.
  • Life insurance cover should equal at least 15 to 20 times your annual income.
Common Pitfalls
  • Treating life insurance as an investment vehicle.
  • Surrendering existing traditional policies rashly without calculating surrender penalty losses.
07

Frequently Asked Questions

Most traditional endowment policies deliver an annualized net return (IRR) between 4.5% and 6.0%, which barely matches long-term consumer inflation.
