Design a gilt ladder vs holding a floating short-duration fund (ERNS). Planning tool, not advice — figures reflect the prices you enter.
Paste from your broker / Tradeweb / DMO. Coupon is the annual rate (%). YTM, accrued and dirty price compute live. Accrued is optional — leave blank to auto-calc.

Optimise picks the highest-yielding gilt in each maturity year (after-tax in a GIA). Randomise picks a random valid gilt per year — watch the blended YTM drop, then Optimise to restore it. You can also override any single rung below.

Compare the ladder like-for-like against anything you type in (name + yield) — your current fund, a fixed savings bond, a money-market fund. Same capital, same horizon, terminal value & return for each. Floating benchmarks move with the rate path; fixed ones stay put.
| Name | Yield % | Type |
|---|
Single gilt (bullet) = all capital in one long gilt held to maturity — the concentrated alternative to spreading across rungs.
| Strategy | Type | Start yield | Terminal (£) | Return p.a. | vs Ladder (£) |
|---|
Same strategies, three rate paths. The single gilt wins when rates fall (locked-in high yield); the ladder catches up or wins when rates rise (maturing rungs reinvest higher). Winner per column in green.
| Strategy | Rates fall (sharp cuts) | Flat | Rates rise (+0.5%/yr) |
