About this calculator

Stepped premiums start cheap but climb every year as you age. Level premiums start higher but stay flat. Crossover — the year a level policy becomes cheaper cumulative — is usually 10–15 years in.

  • If you only need cover for 5 years, stepped wins.
  • If you need cover for 20+ years (typical for life or trauma to age 65), level wins decisively.
  • Level premium is locked at entry age — taking it out at 30 is materially cheaper than at 45.

Frequently asked questions

Can I switch later?
You can convert stepped to level at most insurers but the rate is set at conversion age, not original entry age — so the early advantage is lost.
