Quick answer
- The conventional hourly equivalent uses the annual salary and paid hours entered.
- Actual unpaid additional hours can lower the effective hourly rate.
- Paid annual leave normally remains inside the full-year salary.
- Identical salaries can have different hourly values when contracted hours differ.

Contractual hourly equivalent
The calculator’s primary result spreads annual gross salary across the paid hours in the work pattern entered. It is useful for comparing a salaried role with an hourly offer or comparing two contracts with different weekly hours.
Effective hourly rate from actual time
If the contract states one weekly total but the job routinely requires unpaid additional hours, run another calculation with the realistic hours. The second result is an effective comparison rate, not a change to the contractual salary.
Paid weeks versus working weeks
A 52-week salary can include weeks spent on paid annual leave. Do not automatically replace 52 with 48 merely because an employee receives four paid working weeks of leave. Use fewer paid weeks only where part of the year is genuinely unpaid.
Comparing 37.5, 39 and 40-hour contracts
The longer the weekly hours for the same annual salary, the lower the gross hourly equivalent. Use the exact contracted paid hours for each offer. Do not apply one employer’s 37.5-hour pattern to another employer’s 40-hour role.
Daily value needs working days
Weekly hours alone do not reveal daily pay. The same hours could be arranged over four or five days. The calculator therefore asks for working days and divides weekly gross pay by that pattern rather than forcing every role into five days.
Use two passes for a fair offer comparison
- Use contracted paid hours to find the contractual gross hourly equivalent.
- Use realistic actual hours to test whether unpaid additional time changes the comparison.
- Review leave, pension, overtime, benefits and commute separately.
- Use the Net Salary Calculator for the after-tax annual amount.
Worked example: €45,000 salary at different weekly hours
The formula and inputs
Gross hourly equivalent = annual gross pay ÷ (weekly paid hours × paid weeks). Use the gross pay for the same period as the hours. This is a planning conversion before PAYE, USC, PRSI and pension deductions, not a payslip or a legal minimum-wage assessment.
Assume a full-year €45,000 base salary, 52 paid weeks, no bonus and no separately paid overtime. Paid annual leave is already included. Change only weekly hours:
| Hours per week | Annual paid hours | Calculation | Gross hourly equivalent |
|---|---|---|---|
| 37.5 | 1,950 | €45,000 ÷ (37.5 × 52) | €23.08 |
| 39 | 2,028 | €45,000 ÷ (39 × 52) | €22.19 |
| 40 | 2,080 | €45,000 ÷ (40 × 52) | €21.63 |
Round the final rate to two decimal places; do not round annual hours first. A 40-hour role pays the same annual salary here but requires 130 more contracted paid hours than a 37.5-hour role.
What recurring unpaid extra hours change
If the 37.5-hour role regularly requires 45 hours in a working week without extra pay, a second scenario using the same 52-paid-week basis gives €45,000 ÷ (45 × 52) = €19.23 per hour. That is a comparison equivalent about 16.7% below the contracted-hours result; it does not change the contract rate.
This second scenario is not a timesheet calculation of hours actually worked over the year: the 52-week convention includes paid leave. To measure pay per actual hour worked, divide the pay received by your recorded total working hours for that same period. Keep that measure separate from the paid-hour equivalent above.
Paid leave is different from an unpaid break
Do not change 52 paid weeks to 48 merely because you take four weeks of paid annual leave. The WRC explains paid annual-leave entitlements, including for hourly and part-time employees.
For a different example, assume four genuinely unpaid weeks and that the employer prorates a €45,000 full-year salary using 48 ÷ 52. Gross pay received is then €41,538.46. Enter that amount, 37.5 hours and 48 paid weeks: €41,538.46 ÷ (37.5 × 48) is approximately €23.08 per hour. Entering the unchanged €45,000 with 48 weeks would instead give €25.00 and would misrepresent this unpaid-break example. Use the employer’s actual proration terms.
Reproduce it with your own salary
- Enter the gross base pay you expect to receive for the year.
- Enter contracted paid hours, excluding unpaid breaks, and paid weeks.
- Use days per week only for the daily equivalent; it does not change the hourly result.
- Save a second scenario if recurring unpaid extra hours matter.
- Compare offers using the job-offer comparison guide, then estimate take-home pay separately.
Frequently asked questions
How do I calculate hourly rate from salary?
Divide gross annual pay by weekly paid hours multiplied by paid weeks. For €45,000, 37.5 hours and 52 paid weeks: €45,000 ÷ 1,950 = €23.08 per hour. Paid leave stays within paid weeks; use the pay actually received if part of the year is unpaid.
What is an effective hourly rate?
It is the salary divided by the hours actually required. It can be lower than the contractual equivalent if unpaid additional hours are common.
Should I use 52 or 48 weeks?
Use 52 for a normal full-year paid salary, including paid leave. Use fewer only for genuinely unpaid periods.
Why do 39 and 40 hours give different results?
The same salary is spread across a different number of paid annual hours.
Does days per week change hourly pay?
No. Weekly paid hours determine the hourly result. Days per week determine the daily equivalent.
Is the result before tax?
Yes. Move the annual salary into the Net Salary Calculator for an estimated after-tax result.
Should bonuses be included?
Keep uncertain bonuses separate. Add only guaranteed salary when establishing the base hourly value.
