Competition-improved core tool

Notice Period Calculator

Page purpose

This page is for users who need the notice length and likely end date before checking final pay.

Estimate the statutory minimum notice period an employee should receive, compare it with any longer contractual notice, and optionally see an estimated notice end date.

Why this page was improved:

Competing notice tools often win by helping users work out their actual last day. This version keeps the legal comparison logic but adds a practical notice-end-date output too.
