£45,000.00 a year, on 37.5 hours over 5 days with 5.6 weeks off, is £23.08 an hour, £173.08 a day, £865.38 a week and £3,750.00 a calendar month. Because your holiday is paid, the same salary is £25.86 for each hour you are actually at work, which is 12.07% higher. Every figure here is gross pay, before Income Tax, National Insurance, pension contributions and any student loan deduction.
These set your working pattern only. None of them touches the amount you entered and none of them is a typical figure. UK full time contracts are commonly written at 35, 37.5 or 40 hours, so use whichever one your own contract says.
Four weekly pay is 13 payments a year and calendar monthly is 12, so the same £45,000.00 shows as £3,461.54 on one payslip and £3,750.00 on the other. Same salary, different frequency.
The at-work figure is higher because your holiday is paid, so the same money is spread over fewer hours actually worked. The first figure is what you are paid per hour. The second is what an hour of your attendance works out at, and it is the start of a staff cost rate, before employer National Insurance, pension and overheads, which this page does not calculate.
The National Minimum Wage and National Living Wage are set as hourly rates, vary by age band and change each April, so this page does not hold them. Check a rate against the current figures on GOV.UK.
Pro rata scales an advertised salary. An hourly or a daily rate is not scaled by it, which is the point of pro rata.
This page is general information about converting gross pay between periods, not financial, tax or legal advice. For anything that depends on your own circumstances, check GOV.UK or ask a qualified adviser.
Every figure on the ladder comes from the same two-step model: normalise once, then project outwards. That is the whole trick, and it is why the rows always reconcile with each other.
Whatever you type is turned into annual gross once, at full precision. £3,750 a month becomes 3,750 × 12 = £45,000. £450 a day at 5 days over 44 paid weeks becomes 450 × 5 × 44 = £99,000.
Quarter is annual ÷ 4, calendar month ÷ 12, four weekly ÷ 13, fortnight ÷ 26, week ÷ 52. Annual leave never enters these while time off is paid, because the calendar does not shrink when you are on holiday.
The hour and day figures divide by your own schedule: 52 weeks of your hours if your holiday is paid, or the weeks you actually work if it is not. Those divisors are printed under the rungs so you can check them.
No row is derived from another displayed row. Round a week, multiply it back up, and the year drifts by pounds. Every row divides the one unrounded annual figure, and rounding happens only at the screen.
Hours a week and weeks a year are the whole divisor, and both are yours, not ours. Contracted hours normally exclude an unpaid lunch, so 09:00 to 17:30 with 30 minutes unpaid is a 7.5 hour day, not 8.5, and a one hour error in the weekly figure moves the hourly answer on a £45,000 salary by roughly 60p. If you need the hours themselves, from a start time and a finish time less unpaid breaks, the hours worked calculator does that.
A year holds 52 weeks and 12 months, so a month averages 52 ÷ 12 = 4.3333 weeks. Divide £45,000 by 12 and then by 4 and you get £937.50 a week against a true £865.38, which is £72.12 or 8.33 per cent too high, because dividing by 12 and then by 4 quietly assumes a 48 week year. Push it back out and the error is obvious: £937.50 × 52 is £48,750, exactly one extra month's pay. The hourly figure inherits it as £25.00 against £23.08, and £25.00 looks so tidy that nobody questions it. One more honesty note: 4.3333 is an average across the year, so if you are paid weekly or hourly, your real monthly income varies with 28 to 31 day months, and the monthly row is a smoothed average rather than a payment that lands on a date.
The line this page draws is whether your time off is paid, not whether you are an employee. Salaried staff and hourly paid employees with statutory leave are paid across all 52 weeks, so their hourly rate divides by 52 weeks of hours, and their at-work figure divides by the weeks left after leave. Day rate contractors, consultants and freelancers are paid only for time worked, and weeks worked then dominates the annual figure: £450 a day over 5 days is £99,000 at 44 weeks and £108,000 at 48, which is why this tool refuses to pick that number for anyone. One UK wrinkle worth knowing: bank holidays differ across the nations, usually 8 in England and Wales, 9 in Scotland and 10 in Northern Ireland, so a practice with offices in more than one UK nation has a different weeks-at-work figure per office.
Gross is pay before anything comes off. Income Tax, National Insurance, pension contributions, student loan deductions and salary sacrifice all sit between the figures on this page and the money that reaches your bank, and this page prices none of them, because rates and thresholds change every tax year and a stale figure is worse than no figure. For Income Tax and National Insurance, use GOV.UK.

There is no single national hours figure, which is exactly why the tool asks for yours. The salary does not move in this table. The hourly figure moves substantially, and a converter that hard codes a 2,080 hour year has silently picked the 40 hour column for you.
| Annual salary | Per hour at 35 hours | At 37.5 hours | At 40 hours | At 45 hours |
|---|---|---|---|---|
| £25,000 | £13.74 | £12.82 | £12.02 | £10.68 |
| £30,000 | £16.48 | £15.38 | £14.42 | £12.82 |

Two honest answers, for two different questions. Hours you are paid for: 52 weeks times your contracted week, so 1,820 at 35 hours, 1,950 at 37.5, 2,080 at 40 and 2,340 at 45. Hours actually at work at statutory minimum leave, which is 46.4 weeks: 1,624 at 35 hours, 1,740 at 37.5, 1,856 at 40 and 2,088 at 45. The 2,080 figure you see in US tools is not a fact about a UK contract: it is 52 × 40, a constant that hard codes a 40 hour week.
The basis matters as much as the rate. An hourly paid employee with paid holiday is paid across 52 weeks, so £15.00 at 37.5 hours is £29,250 a year. The same £15.00 with unpaid time off over 46.4 worked weeks is £26,100. This table uses the paid basis, and the tool will show you both.

The National Minimum Wage and National Living Wage are set as hourly rates, vary by age band and apprentice status, and change each April, so no figure is printed here: rates and thresholds change every tax year, so this page holds none of them. Compliance also turns on pay reference periods and deductions this tool does not model. The current rates are on GOV.UK, and that is deliberately where this page stops.
Multiply the month by 12, never by 13 and never by four week blocks. If you are paid four weekly rather than by calendar month, you get 13 payments a year and a different payslip figure on the same salary, which the tool's ladder shows side by side.

A day rate is not a fixed number of hours, and the same rate is a different hourly figure at different day lengths: £500 a day is £66.67 an hour at 7.5 hours, £62.50 at 8 and £50.00 at 10. Half day terms break the equivalence further, and a day rate rarely pays overtime, so long days cost the client nothing. An hourly equivalent of a day rate is only meaningful across a run of full days, never on a single one.

Three arithmetically correct answers to three different questions on £60,000: £230.77 over 260 contracted days, £258.62 over the 232 days actually worked after 5.6 weeks off, and £272.73 at 44 working weeks. The at-work basis, per day actually worked, is the only basis on which a salary and a day rate are even comparable. And gross for gross is still not the whole deal: a salary carries paid holiday, statutory sick pay entitlement, employer pension contributions, employer National Insurance, and notice and redundancy rights, none of which sit inside a day rate. This page names them and stops there, because pricing them is payroll and would be a guess.
| Employee salary | Day rate at 220 billed days | At 232 billed days | At 240 billed days |

| £30,000 | £136.36 | £129.31 | £125.00 |

There is no number this page will supply, and that refusal is the honest answer: holiday, gaps between contracts, sickness and unsold time are all yours, and no average describes them. What the page will show you is the sensitivity. £450 a day over 5 days is £99,000 at 44 weeks, £104,400 at 46.4 and £108,000 at 48, so a four week assumption moves the annual figure by £9,000. The tool prints the same spread live under the weeks input when your time off is unpaid. How much of a paid year actually reaches a client invoice is a different question again, called utilisation, and it has its own calculator.
Scale first, convert second. Your actual salary is the advertised full time salary times your hours divided by the full time hours, and every other figure follows from the scaled amount. Part time workers get the same 5.6 weeks of statutory leave pro rata.
| Full time equivalent salary | 0.8 FTE (30 hours) | 0.6 FTE (22.5 hours) | 0.5 FTE (18.75 hours) |
|---|---|---|---|
| £25,000 | £20,000 | £15,000 | £12,500 |

£45,000 pro rata for 22.5 of 37.5 hours is £27,000, and the hourly figure is £23.08 either way. That invariance is exactly what pro rata means: the money scales with the hours, so the rate for an hour does not move.

A calendar year is 52 weeks and 1 day, or 2 in a leap year, which is why weekly, fortnightly and four weekly pay cycles occasionally produce an extra pay date. And you will not find the US pay cycles here: no twice-a-month row and no US word for a two week cycle, because UK payroll says fortnightly and pays 26 times a year, or four weekly and pays 13.
Every figure this page produces is gross: pay before anything is deducted. It does not estimate what lands in your bank, it holds no tax bands or thresholds, and it never will, because a figure embedded in a page is stale the moment the tax year changes.
Income Tax, National Insurance, pension contributions, student loan deductions and salary sacrifice. They are named here so you know what sits between the gross figure and the money that arrives, and priced nowhere on this page: no band, no threshold, no allowance, no rate.
GOV.UK for Income Tax and National Insurance, GOV.UK for holiday entitlement and holiday pay, GOV.UK for National Minimum Wage rates, and an accountant or a qualified adviser for anything that depends on your own circumstances. Worth knowing when you check: a UK tax year runs 6 April to 5 April, so a year of pay can straddle two tax years.
Tax bands, thresholds and allowances change every tax year, and a marketing page is the wrong place to maintain them. Quantim records time against staff rate cards and cost rates and turns that time into fees and invoices, with utilisation, WIP and profitability reporting. It does not run payroll, does not calculate deductions and does not file anything with HMRC. Naming the destination instead of guessing is the whole policy: for deductions, GOV.UK; for pay conversion, this page.
The at-work hourly figure on the ladder, annual gross divided by the hours someone is actually at work, is the salary component of a staff cost per hour: salary plus employer National Insurance, pension and overheads, divided by their working hours. This page gives you the first part and stops.
Employer National Insurance, employer pension contributions and a share of overheads sit on top of gross pay, and this page does not calculate them because that is payroll. Employer National Insurance rates and thresholds change every tax year, so this page will not put a figure in for you and does not hold one anywhere. Your payroll run has all three.
Three numbers get confused here: gross pay to the person, cost to the business, and price to the client. This page only ever does the first. The third is a charge-out rate, and that is the charge-out rate and margin calculator's question: it already takes a staff cost per hour as an input and derives the rate to set from a target margin, which is why neither page repeats the other.
Quantim holds cost rates against each person with effective dates, keeping the full history as rates change, and rate cards carry charge rates and cost rates by Job, Activity and Grade. Both are held in hours, which is why a day rate has to be expressed as an hourly rate and a day length before it can be used, and that is a genuine reason this converter is useful to a Quantim customer. Rate card management is part of the features and plans, and the recorded time behind it feeds the cost and profitability reports.
A converter tells you what an hour is worth. Quantim records the hours themselves, against jobs and activities, billable and non billable, and turns them into fee invoices, with utilisation, WIP and profitability reporting on top and invoicing that connects to Sage, Xero and QuickBooks. You can watch hours become a fee invoice step by step in the interactive demo.

Divide the salary by the hours you are paid for in a year, which is your contracted hours a week multiplied by the weeks a year you are paid for. A salaried employee is paid through their holiday, so a 37.5 hour week across 52 weeks is 1,950 hours, and a salary of £45,000 comes to £23.08 an hour. On a 40 hour week the divisor is 2,080 and the same salary is £21.63 an hour. The hours assumption changes the answer completely, so always say which one you used.
On a 37.5 hour week paid across 52 weeks, £45,000 a year is £3,750.00 a month, £865.38 a week, £173.08 a day on a five day week, and £23.08 an hour. Those figures are gross, before Income Tax, National Insurance and any other deductions.
£2,500.00 a month gross. Divide any annual salary by 12, because UK monthly pay dates are twelfths of a year. On the same salary, a 37.5 hour week works out at £576.92 a week and £15.38 an hour.
No, and it is the most common mistake in pay conversion. A year holds 52 weeks and 12 months, so a month is 52 divided by 12, which is 4.3333 weeks. Multiplying weekly pay by four gives you about 92.3 per cent of a month, understating it by roughly 7.7 per cent. Multiply by 4.3333 instead, or divide the annual figure by 12.
It depends on your contracted week and on whether you are paid through your holiday. A salaried employee on 37.5 hours is paid for 1,950 hours a year, and on 40 hours for 2,080 hours. Someone paid only for the weeks they actually work has fewer: at 37.5 hours across 46.4 weeks, which is 52 less the 5.6 weeks of statutory minimum annual leave, it is 1,740 hours.
A five day week across 52 weeks is 260 days, and that is the figure to use for a salaried day rate, because paid holiday already sits inside the salary. If you want the days actually worked, take your leave off: the statutory minimum of 5.6 weeks is 28 days for a five day week, which leaves 232.
Divide the salary by the days you expect to be paid for. A salaried employee is paid for 260 days, so £50,000 is £192.31 a day. A self employed contractor is not paid for holiday, sickness or gaps between contracts, so divide by the days you actually expect to bill: £50,000 over 232 billed days is £215.52 a day. Neither figure includes employer pension contributions, employer National Insurance, paid holiday, sick pay or business costs, so a day rate that only matches a salary is not the same deal overall.
£2,500 a week on a five day week, and the annual figure depends entirely on how many weeks you bill. At 44 billed weeks it is £110,000, at 46.4 weeks it is £116,000, and at 48 weeks it is £120,000. Those are gross turnover figures, before business costs and before tax.
Multiply the full time salary by your share of a full time week. Three days on a 37.5 hour week is 0.6 of full time, so £30,000 pro rata is £18,000. Pro rata scales the salary and leaves the hourly rate alone: at £30,000 full time equivalent, the full timer and the part timer are both on £15.38 an hour.
No. Every figure on this page is gross pay, before Income Tax, National Insurance, pension contributions, student loan repayments and anything else deducted from your pay. Quantim is timesheet and fee management software and does not run payroll, so we do not publish tax bands or thresholds and we do not work out net pay. For Income Tax and National Insurance, use the official calculators and the current thresholds on GOV.UK.
No. Gross pay per hour is only the first part of a staff cost rate. An employer also pays employer National Insurance and pension contributions on top, and carries the overhead of employing someone, and a cost rate is usually spread over productive hours rather than every paid hour, which raises it again. Treat the hourly figure here as the starting point and add your own on-costs. Quantim holds staff cost rates and rate cards so those figures sit against each person and feed project costs and profitability reports.
Not on its own. What you pay someone and what you bill a client for an hour of their time are different numbers, and the gap between them is your margin. Work out the gross hourly figure here, add your own employer on-costs to reach a cost per hour, then use the Quantim charge-out rate and margin calculator, which turns a cost per hour and a target margin into the rate you should be billing.
Because they are measuring different things. Chargeable weeks a year is how many weeks a fee earner is available to bill clients, which is what the ROI and utilisation calculators need. This page asks how many weeks you are paid for, which for a salaried employee is all 52, holiday included, and for a self employed person is only the weeks they expect to bill. Using 52 for a contractor overstates their year, and using it for fee capacity overstates the firm's.
