Free tools for agency recruiters
The sums a perm and contract desk does every week, with the working shown. No sign-up, nothing stored, and every assumption on the screen where you can change it.
Placement fee and rebate calculator
Work out a permanent placement fee from salary and fee percentage, the invoice with VAT, and exactly what you would refund at each week of your rebate scale.
Contract margin and mark-up calculator
Enter a charge rate and pay rate to see margin per day, margin percentage, mark-up and gross profit across the contract. Or work backwards from a target margin.
Day rate to salary calculator
Convert a UK contractor day rate into an equivalent permanent salary, or a salary into a day rate, with the assumptions shown: billed days, benefits and running costs.
Recruiter commission calculator
Work out recruitment consultant commission from billings, a threshold and tiered rates, and compare banded with retrospective schemes on the same numbers.
Contract gross profit calculator
Work out the gross profit on a contract from charge rate, pay rate and length, including an extension at new rates and a one-off cost, with a week-by-week table.
Charge rate to contractor take-home calculator
From the charge rate to what a contractor is likely to keep: the pay rate after agency margin, an umbrella company worked through to net pay, and a limited company shown as gross. Illustrative.
Rebate exposure calculator
See how much of your permanent fees is still inside a rebate period across several placements, what you would refund if each candidate left today, and when the exposure ends.
What each calculator works out
Every calculator shows its working and lets you change the assumption it starts from. Nothing you enter is stored or sent anywhere. The defaults are worked examples, not recommendations, and each sum is explained on the page it belongs to, so you can check the method before you rely on the number.
Placement fee and rebate calculator
Multiplies a salary by your fee percentage, adds VAT at 20 per cent, and then shows what you would refund in each week of a rebate ladder. It assumes the ladder starts from the candidate's first day and that the fee is charged on base salary, so change both if your terms differ. The method behind the ladder is in what a rebate period is, terms of business is where the scale is agreed, and placement fee defines the fee itself.
Contract margin and mark-up calculator
Takes a charge rate and a pay rate and returns the gap as both a margin, measured on what you charge, and a mark-up, measured on what you pay. It also works backwards from a target margin to the charge rate you need. It assumes a contractor paid through their own limited company, so the gap is close to gross profit before funding and bad debt (see PSC versus umbrella and how a timesheet becomes an invoice). Mark-up versus margin explains why the two percentages differ, and contract margin covers what the gap has to pay for.
Day rate to salary calculator
Turns a day rate into the annual income it produces, by multiplying by the days actually billed and taking off running costs, so that it can be set against a permanent salary. It assumes 220 billed days a year, which leaves room for bank holidays, leave, sickness and the gap between contracts, and it ignores tax on purpose. Day rate defines the figure, IR35 explains why the take-home depends on status, and PSC versus umbrella sets out the routes.
Recruiter commission calculator
Applies a tiered scheme to a consultant's billings and shows the commission under both banded and retrospective rules, on the same numbers, so the difference between them is visible. It assumes billings are perm fees plus contract margin, net of VAT, and that commission starts only once billings pass a threshold you set. Recruiter commission sets out how schemes are built, and billings covers what counts towards them.
Contract gross profit calculator
Takes a charge rate, a pay rate, the days or hours a week and the length of the contract, then adds an extension at its own rates and takes off any one-off cost, giving the gross profit for the initial term, the extension and the total, with a week-by-week table. It assumes whole weeks and rates net of VAT, so bank holidays, funding costs and bad debt are not in it. The sums behind it are in how a timesheet becomes an invoice, and contract extensions covers the paperwork that follows a rate change.
Charge rate to contractor take-home calculator
Starts from the charge rate, takes off the agency margin, and shows what an umbrella company would pay out after its fee, employer National Insurance, the Apprenticeship Levy, income tax and employee National Insurance, beside what a limited company is paid gross. It is illustrative: it uses the 2026 to 2027 rates from GOV.UK, assumes no pension or student loan, and gives no take-home for a limited company. PSC versus umbrella explains the two routes, and IR35 why the route is not always a choice.
Rebate exposure calculator
Takes up to six placements with their start dates and fees, applies one rebate ladder, and shows which week each is in, what you would refund if the candidate left today, when the exposure ends, and a month-by-month view of it falling away. It assumes weeks run from the start date and that the fee is before VAT. It uses the same ladder as the placement fee calculator, and what a rebate period is explains why it matters to know the total.
The sums are the easy part. Keeping the rates, the rebate dates and the approved hours attached to the placement they belong to is the work, and it is what Vayora's finance engine is for.
