The result breaks your service into individual years and shows how many fell into each age band, because the multiplier that applies to each year depends on how old you were during that specific year, not your age now. Someone who worked from age 38 to 44, for example, would have some years counted at the lower multiplier (while under 41) and the rest at the higher one (from 41 onward) — the calculator handles this transition automatically rather than applying one flat rate to the whole length of service. This is also why the same total number of years' service can produce a different result for two different people: it's not just about how long you worked, but which specific ages that service fell across.
For each full year of service (most recent 20 years only), based on your age at the end of that specific year: 1.5 weeks' pay if you were 41 or older, 1 week's pay if 22–40, or half a week's pay if under 22 — all added together, using your weekly pay capped at the statutory limit.
Employment law in Northern Ireland is set separately from Great Britain and uses its own weekly pay cap and maximum, which are typically slightly higher.
The statutory formula only counts a maximum of 20 years of service, even if you worked there longer — the most recent 20 years are what's used, so earlier years beyond that don't add anything further to the calculation.
