Bond ladder: 10k 1-year at 4%, 10k 3-year at 4.5%, 10k 5-year at 5% = weighted 4.5% average yield, 1,350 annual income. Laddering spreads maturity risk and reinvestment risk — a single 5-year bond locks rate if market rises.

A worked example

Try the defaults: 1-year amount of 10,000, 1-year yield of 4%, 3-year amount of 10,000, 3-year yield of 4.5%. The tool returns 4.50%. You can adjust any input and the result updates as you type — no submit button, no reload. That's the real power here: seeing how sensitive the output is to one or two assumptions.

What moves the number most

The result responds to 1-Year Amount, 1-Year Yield, 3-Year Amount, 3-Year Yield, and 5-Year Amount. Not every input has equal weight. Flip one at a time toward extreme values to feel which ones move the needle most for your situation.

Using this well

Treat the output as one point on a wider map. Run it three times — a pessimistic case, a central case, and a stretch case — and plan against the pessimistic one. That habit alone separates people who stick with an investment plan from those who bail at the first wobble.

What this doesn't capture

Steady-rate math ignores real-world volatility. Actual returns are lumpy; sequence-of-returns risk matters most in drawdown; fees and taxes drag on compound growth; and behaviour changes in drawdowns can reduce outcomes below the projection. Treat the number as one scenario, not a forecast.

What to calculate alongside this

One figure by itself is fragile. The bond yield calculator, the yield to maturity calculator, and the bond ladder income calculator cover adjacent ground — the answer to any one of them changes how you read the output from this tool. Worth a few minutes each, honestly.

Example Scenario

Bond ladder yield produces a weighted average based on the inputs provided.

Inputs

1-Year Amount:10,000 £
1-Year Yield:4
3-Year Amount:10,000 £
3-Year Yield:4.5
5-Year Amount:10,000 £
5-Year Yield:5
Expected Result4.50%

This example uses typical values for illustration. Adjust the inputs above to match a specific situation and see how the result changes.

Frequently Asked Questions

Why ladder?
Diversifies reinvestment risk. If rates rise, maturing bonds roll at higher yields. If rates fall, longer bonds preserve yield.
Rungs count?
3-5 common. More rungs smoother but more admin. Gilts, Treasuries, high-grade corporates all laddered.
Reinvest at maturity?
Typically buy new longest rung — keeps ladder shape. Rolling strategy automatic after setup.
Tax-efficient wrapper?
tax-advantaged savings account, tax-advantaged pension account, or equivalent shelters interest. Outside wrappers, interest taxed at marginal rate.
