This extension page exists to support specific long-tail queries with formula-first explanations. It is intentionally narrow, deliberately opinion-free, and designed to lead into the relevant calculator rather than replace it.

Core Formula

Scenario comparison frame
Annual pension input = salary x employee rate + salary x employer rate
  • Employee rate changes current take-home and long-run funding
  • Employer rate adds to funding
  • Projection horizon and return assumptions shape the gap between scenarios

Why scenario pages are useful for pensions

Pension decisions are rarely binary. Users often compare one contribution rate against another or test what happens when matching improves.

Scenario pages fit that behaviour well because they stay numerical and auditable.

Why matching deserves special attention

Employer matching can change the economics of a contribution decision materially.

That is one reason scenario pages are more useful than single-point examples.

FAQ

Why do small percentage changes matter so much?

Because the extra annual funding compounds over many years, amplifying what initially looks like a small difference.

Should I only look at the final pot?

No. Current cash-flow impact matters too, especially when contributions materially change take-home pay.
