What it is:: A comparative financial modeling calculator pitting Buy Term and Invest Difference (BTID) against traditional endowment policies.
What it calculates:: Comparative life protection cover, total outflows, maturity corpus differential, and internal rate of return (IRR).

Key Assumptions

Endowment plan delivers 5.0% long-term IRR.
Mutual fund SIP earns 11.5% long-term equity CAGR.
Term policy provides minimum ₹1 Crore cover.

How it works

Traditional Endowment Fallacy: Traditional life insurance plans combine insurance with investment, resulting in poor life cover (only 10x annual premium) and low returns (typically 4.5%–5.5% CAGR).

Buy Term and Invest Difference (BTID): A small fraction of your budget is used to buy a pure term plan with ₹1 Crore cover. The entire remaining balance is invested in an Equity Mutual Fund SIP or PPF.

Life Protection: In BTID, your family is protected with 5x to 10x higher sum assured during your working years.

Maturity Wealth: The invested difference compounds at 11%–12% in mutual funds, yielding 2x to 4x higher wealth at maturity compared to traditional insurance bonuses.

Formula

Maturity Wealth Difference = (SIP Future Value of Saved Premium) - (Traditional Endowment Maturity Payout)

SIP FV: = Compounded corpus from investing the premium difference at market rates
Endowment Payout: = Guaranteed sum assured + declared annual reversionary bonuses
Life Cover: = ₹1 Crore pure term cover vs ~₹10-15 Lakhs endowment cover

Traditional policy returns have historically trailed bank fixed deposits and cost of living inflation.

Frequently asked questions

Why do traditional life insurance plans offer such low returns?

Traditional endowment and money-back plans have high upfront agent commissions (up to 25%–35% of the first year premium) and invest predominantly in low-yielding government securities and bonds, resulting in net returns of barely 4.5% to 5.5% per annum.

What is Buy Term and Invest the Difference (BTID)?

BTID is a proven financial strategy where an investor buys high-coverage, low-cost pure term insurance (e.g. ₹10,000/yr for ₹1 Crore cover) and systematically invests the remaining budget (e.g. ₹90,000/yr) into equity mutual funds or PPF, separating risk protection from wealth creation.

Is the maturity payout of traditional plans tax-free?

Under Section 10(10D), maturity proceeds were historically tax-free if the annual premium did not exceed 10% of the sum assured. However, Finance Act 2023 amended Section 10(10D) to mandate that for traditional policies issued on or after 1 April 2023 with aggregate annual premium exceeding ₹5,00,000, maturity gains are fully taxable as income.
