What this calculator answers

Five ₹2,00,000 rungs maturing in years 1–5 at a 7% coupon assumption pay ₹2,70,000 in year 1 falling to ₹2,14,000 in year 5, with an average maturity of 3 years. Enter each rung's face to see the yearly cash schedule.

How it is calculated

Each rung pays its annual coupon every year until it matures, when its face joins the coupon as cash; totals are summed per year with no reinvestment of maturing face, and average maturity is face-weighted.

One shared coupon assumption across rungs (kept simple on purpose); maturing face is shown as cash, not compounded.

Common questions

Why ladder instead of one long bond?

Something matures every year, so reinvestment spreads across rate cycles and no single maturity date decides your outcome.

Is the coupon guaranteed?

No — it is your assumption. Government coupons are contractual but corporate ones depend on the issuer paying.

What does average maturity tell me?

Roughly how long your money is locked on average — higher means more rate sensitivity and usually more yield.
