2 · Ladder configuration

Rungs — one gilt per maturity year

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.

Ladder vs benchmarks

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.

Single gilt (bullet) = all capital in one long gilt held to maturity — the concentrated alternative to spreading across rungs.

Scenario summary — terminal value if rates…

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.
