Equivalent Salary Calculator UK
Equivalent salary calculators are most useful when the gross salary is technically the same role but not the same working pattern. If one job is full-time, another is compressed hours and another is term-time or part-time, you need a full-time-equivalent view before judging the pay.
This page converts salary across weekly hours and working weeks so you can compare offers and role changes on a fair basis.
Convert salary to an equivalent workload
Enter the current salary and work pattern, then the target hours and weeks you want to compare against.

How this calculator works
The logic is simple but important: it converts the current salary into an hourly value based on weekly hours and working weeks, then rebuilds that value using the target workload. That gives you a like-for-like salary comparison even when the roles are not the same pattern.
This is especially useful in part-time, term-time, four-day-week or compressed-hours conversations where the advertised salary does not tell the whole story.
Worked example
A £32,000 job at 30 hours a week across 46 weeks is not equivalent to a £32,000 role at 37.5 hours across 52 weeks. Once you convert the salary into a consistent hourly workload, the real equivalent becomes much clearer.
That matters for internal role changes, flexible working requests and negotiations where an employer says a salary is “the same” while the workload assumption has changed.
2025/26 rates, thresholds, and inputs
Because this is a workload-equivalence tool rather than a tax tool, it deliberately stays focused on time and gross pay.
| Input | What it represents |
|---|---|
| Current salary | Your existing gross annual pay |
| Current weekly hours | Contracted hours per week |
| Current weeks | Weeks actually worked or paid |
| Target hours | The workload you want to compare against |
| Target weeks | The target annual working pattern |
Edge cases and assumptions
- The calculator treats salary as being spread evenly across the stated working pattern.
- It does not price overtime premiums or shift allowances separately.
- If your employer uses annualised hours, convert them into an average weekly figure first.
- Term-time roles should use the actual paid or worked weeks, depending on what you are comparing.
FAQs
What is an equivalent salary?
It is the salary that would represent the same hourly earning value under a different workload, such as moving from part-time to full-time.
Is this the same as full-time equivalent salary?
Usually yes. Full-time equivalent, or FTE, is one of the most common uses of an equivalent salary calculation.
Can I use this for compressed hours?
Yes, as long as the total weekly hours and weeks are accurate.
Sources and methodology
This page uses a straightforward workload-equivalence model rather than tax rules. The goal is comparability across hours and weeks worked.
