Endowment Policy Calculator

Insurance

An endowment plan pays a guaranteed sum assured plus accrued bonuses if you survive the term. It is safe and predictable — but the effective return is usually low. See what your plan is likely to be worth and what return it really earns.

In short: An endowment policy calculator estimates the maturity value of a traditional endowment plan as the sum assured plus accrued reversionary bonuses, and reveals the low effective return — typically around 4–6% — earned on the premiums paid.

How the Endowment Policy Calculator works

Formula

Maturity = Sum assured + (Sum assured ÷ 1,000 × Bonus per ₹1,000 × Term)
Sum assured
Guaranteed amount payable on maturity or death
Bonus per ₹1,000
Reversionary bonus declared per ₹1,000 of sum assured per year
Term
Number of years the policy runs
Total bonus
Sum of yearly reversionary bonuses accrued

Step-by-step calculation

Worked with the default values.

  1. 1

    Annual reversionary bonus

    (₹10,00,000 ÷ 1,000) × 45

    = ₹45,000

  2. 2

    Total bonus over term

    ₹45,000 × 20 yrs

    = ₹9,00,000

  3. 3

    Maturity value

    ₹10,00,000 + ₹9,00,000

    = ₹19,00,000

  4. 4

    Approx. effective return

    CAGR(₹11,00,000 premiums → ₹19,00,000, 20 yrs)

    = 2.77%

How it works

  • A reversionary bonus is declared each year as a rupee amount per ₹1,000 of sum assured and added to the policy.
  • These bonuses accrue simply (not compounded) over the term and are paid out only at maturity along with the sum assured.
  • Comparing the maturity value with the total premiums paid shows the modest effective annual return the plan delivers.

Examples

₹10 lakh sum assured, 20-year term, ₹45 bonus per ₹1,000

Accrues ₹9 lakh of bonus → ₹19 lakh maturity, an effective return of roughly 5%.

₹25 lakh sum assured, 25-year term, ₹50 bonus per ₹1,000

Bonuses add about ₹31 lakh → a ₹56 lakh maturity, still a low single-digit return.
