Gross Salary Converter: Hourly to Annual Pay
Translate gross pay between periods using the paid hours, days and weeks you enter. A separate daily-rate mode uses your agreed divisor; neither mode calculates take-home pay or a statutory wage floor.

How the calculation works
The converter translates gross pay using a paid schedule, with a separate mode for a specified-period daily rate. These are two explicit arithmetic conventions: neither chooses a payroll divisor for you nor turns gross salary into net pay.
Annualise the entered pay using paid hours, days and weeks; divide the annual amount by the corresponding paid units to convert back. For a specified-period daily rate, divide that period’s gross pay by its agreed day divisor. Gross pay for payable days = unrounded daily rate × payable days.
Choose the relevant mode
Equivalent-period mode annualizes an hourly, daily or periodic pay figure. Daily-rate mode instead divides one specified period’s gross pay by its agreed day divisor.
Use the matching schedule
For equivalent pay, annual paid hours are weekly hours times paid weeks, and paid days use days times weeks. Monthly and quarterly amounts use twelve and four periods respectively.
Read conversions without premature rounding
Equivalent results divide annual gross pay by the corresponding units. Daily mode multiplies the unrounded daily rate by the entered payable days before displaying the gross amount.
Worked example: Hourly conversion
Sample inputs demonstrate the method. They are not a forecast or product offer.
The first example pays €20 per hour for 40 paid hours a week over 52 paid weeks. Multiplying 20 by 40 by 52 gives €41,600 annual gross equivalent. The five-day schedule supplies a consistent daily equivalent without changing that annual total.

Understanding your result
These figures express the same gross amount under the chosen schedule. Changing paid weeks changes hourly or weekly equivalents even when an annual salary remains fixed.
The daily mode can support a stated payroll convention, but it does not determine which days are payable or establish a lawful partial-period payslip.
Questions you might have
What does this salary converter include?
Convert gross pay between hourly, daily, weekly, fortnightly, four-weekly, twice-monthly, monthly, quarterly and annual periods using your paid working schedule.
Which assumptions should I check?
The schedule is an input, not a legal assumption. Unpaid leave, bonuses, tax and overtime premiums are excluded unless already reflected in your pay amount. The specified-period daily mode requires an agreed day divisor; it does not automatically use 30 days, weekdays or attendance as the legal basis.
Choosing the right inputs
- Paid weeks per year
- In equivalent-period mode, enter paid weeks per year, not simply weeks physically attended. Supported schedule inputs are positive, with up to 53 weeks, seven days and 168 hours per week.
- Pay period
- Select the period of the amount entered. Twice-monthly means 24 payments annually; fortnightly uses the stated paid weeks divided by two.
- Agreed day divisor for that pay period
- In daily mode, supply the divisor agreed for the pay period. Calendar-day and working-day conventions can differ; no automatic divisor is selected.
Common mistakes to avoid
- Do not substitute take-home pay and then describe the output as gross salary.
- Overtime premiums, tax, bonus and unpaid leave adjustments are not added unless already reflected in the supplied amount or paid schedule.
