What margin is left?
Margin per week, as a percentage of the bill, and per hour, after the worker's gross pay and on-costs.
RecruitSnap is a free UK decision-support calculator for the margin that survives on a temp placement, after holiday pay, employer NIC and pension. Enter the charge rate, pay rate and hours and read the margin in your browser. It is a calculator, not an applicant tracking system or a hiring product: it does not hold candidates, publish roles or track applications.
Enter the charge and pay rate. RecruitSnap adds the true employer on-costs, holiday, NIC and pension, so you see the margin that survives, not the gap on paper. Instant, in your browser, on 2025/26 rates.
Estimate only, not advice. On-costs on PAYE temps at 2025/26 rates: 12.07% holiday, 15% employer NIC above £96/wk (£5,000/yr secondary threshold), 3% pension on qualifying earnings above £120/wk. Excludes apprenticeship levy and any umbrella margin.
RecruitSnap does one job: it shows what is left of the charge rate once the worker has been paid and the employer on-costs are counted. The calculator above answers these three.
Margin per week, as a percentage of the bill, and per hour, after the worker's gross pay and on-costs.
Holiday pay, employer National Insurance and employer pension are shown as one line, on 2025/26 rates, so the gap on paper is not mistaken for profit.
A simple signal: 20% or more reads as strong, 12% to 20% as OK, and below 12% as thin and worth reviewing.
Not covered: pay bands, visa or sponsor-licence checks, IR35 determinations, candidate records, job adverts or any applicant pipeline. For those, take professional advice.
Recruitment agency owners and desk managers pricing temp placements, and owner-managed businesses checking what an agency's charge rate leaves after the worker's pay and on-costs.
The hourly charge rate, the worker's hourly pay rate and the hours per week.
Weekly margin, margin percentage, margin per hour, on-costs and a simple signal update as you type, in your browser.
Optionally leave your email and we will be in touch. The calculator itself is free and needs no login.
