Find your true hourly rate from your annual salary. See how unpaid overtime, commuting time and lunch breaks reduce the real value of your pay per hour.
Contracted hourly rate = salary ÷ (contracted hours × working weeks). True hourly rate = salary ÷ (total time including overtime, commuting and lunch × working weeks). Net take-home uses 2025/26 England/Wales income tax bands and NI rates.
Why Your True Hourly Rate Matters
Your annual salary divided by contracted hours gives the headline hourly rate — but most workers give significantly more time to work than their contract specifies. Unpaid overtime, daily commuting, and on-site lunch breaks all represent time you cannot use for other purposes that you are not compensated for.
A seemingly generous £35,000 salary (£18.72/hour contracted) can become £14–£15/hour once a 1-hour daily commute and 5 hours of unpaid weekly overtime are included. That difference matters when comparing roles or assessing whether a pay rise truly reflects your contribution.
How the Calculation Works
Total weekly time given to work = contracted hours + unpaid overtime + (commuting minutes × 5 ÷ 60) + (unpaid lunch minutes × 5 ÷ 60).
True annual hours = total weekly time × working weeks per year. True hourly rate = annual salary ÷ true annual hours.
What Counts as Overhead Time?
Unpaid overtime: Time spent working beyond contracted hours without additional pay
Commuting time: Time spent travelling to and from a fixed workplace (not considered working time under UK law, but it is your time)
Unpaid lunch breaks: Time on-site during mandatory break periods where you may still be required to be available
Comparing Roles on a True Hourly Basis
Use this calculator when evaluating multiple job offers. A higher salary with longer expected hours and a longer commute can produce a lower true hourly rate than a lower-salary, shorter-hours, remote role. Total compensation per hour of your time is the most honest comparison metric.
Frequently Asked Questions
How do I convert an annual salary to an hourly rate? +
Divide annual salary by contracted hours per year (weekly hours × working weeks). For £30,000 at 37.5 hours over 47 weeks: £30,000 ÷ 1,762.5 = £17.02/hour. For a true rate, also include unpaid overtime, commuting and lunch hours in the denominator.
Why is the true hourly rate lower than the contracted rate? +
The true hourly rate accounts for all time given to work: unpaid overtime, commuting, and unpaid lunch breaks. These hours increase the denominator (total hours) without increasing the numerator (salary), so the result per hour is lower than the contracted rate.
How does commuting time affect my effective hourly rate? +
A 1-hour daily commute over 235 working days adds 235 hours to your annual time commitment. At a contracted rate of £17/hour, that is £3,995 in time given to work unpaid each year, reducing your true hourly rate by approximately £2.27/hour on a £30,000 salary.
What is the average unpaid overtime in the UK? +
According to TUC research, UK workers average 7.7 hours per week of unpaid overtime — equivalent to working one extra month per year for free. At £17/hour, this is worth over £6,000 in unpaid labour annually per worker.
Does commuting count as working time in UK law? +
Regular commuting from home to a fixed workplace is not counted as working time under the Working Time Regulations. However, travelling from home to different client sites each day (field workers) may count. Commuting time is your personal time — you just cannot use it freely — which is why it is relevant to the true hourly rate calculation.
Should lunch breaks be included in the calculation? +
If your lunch break is unpaid and you are required to remain on-site (or on-call), it represents time you cannot use freely. A 30-minute unpaid lunch over 47 working weeks adds approximately 117 hours per year to your on-site time without additional pay.
How many working weeks are in a year? +
52 weeks minus annual leave. The statutory minimum is 5.6 weeks holiday (28 days for a 5-day week). Most workers therefore work approximately 46–47 weeks per year. This calculator defaults to 47 weeks, representing 5 weeks of holiday taken.
How can I use this to negotiate a pay rise? +
Calculate your current true hourly rate and compare it to market benchmarks (ONS ASHE data by occupation). If unpaid overtime significantly reduces your effective rate, you can present a data-driven case showing your true hourly rate versus market median, strengthening a pay rise request or a renegotiation of working hours expectations.
What is the Working Time Regulations 48-hour weekly limit? +
UK workers cannot be required to work more than 48 hours per week on average (over a 17-week reference period) under the Working Time Regulations 1998. Workers can voluntarily opt out. If you regularly work 60 hours per week under an opt-out clause, your true hourly rate is significantly below your contracted rate.
Is there a legal right to pay for overtime? +
There is no automatic right to paid overtime — it depends on your employment contract. However, your average rate including all hours must not fall below the National Minimum Wage. If overtime takes your effective rate below NMW, your employer must make up the difference.
How does remote working change the true hourly rate? +
Setting commuting time to zero for remote workers eliminates the commuting overhead from the true hourly rate. For many remote workers, this adds £2–£5 per hour to their effective rate compared to the same role with a significant commute — a concrete financial benefit of home working worth quantifying.
How does this compare to contractor rates? +
Contractor day rates appear much higher than equivalent PAYE salaries, but contractors pay their own NI, pension, insurance, and receive no paid holiday. A contractor needs approximately 40–60% more gross hourly rate than a PAYE employee to match on a net income basis. The true hourly rate comparison helps you see if the premium is sufficient.
