Fortnightly Pay Calculator: Payslip-Exact Net Pay Per Fortnight

Fortnightly gross pay is the annual salary divided by the 26 fortnights in a standard year — that part is simple division. The tax side isn't: employers withhold using ATO Schedule 1, a per-pay-period formula, not the annual tax brackets divided by 26. The fortnightly gross is halved, truncated to whole dollars, run through the weekly coefficient formula, rounded to the nearest dollar, then doubled. Because the rounding happens before the doubling, fortnightly withholding is always an even number of dollars — a quick payslip sanity check.

This calculator runs that exact formula, so the net figure should match a compliant payslip to the dollar — most online calculators approximate from annual tax and land a few dollars off. For the tax-table view of the same numbers — amounts withheld per fortnight across both scales, with and without a study loan — see the fortnightly tax table page, or use the tax withheld calculator for any gross amount. For the budgeting side of a fortnightly cycle, see the fortnightly take-home pay guide.

The table below converts common salaries to their fortnightly gross and runs the 2026–2027 Schedule 1 formula on each — the tax-free threshold claimed, no study loan. On a $80,000 salary, $3,076.92 gross per fortnight has $622 withheld, leaving $2,454.92in the bank each payday. Enter your own salary above — or your actual payslip gross, which picks up overtime and allowances the salary conversion can't see.

26 fortnights cover exactly 364 days, so each year the pay cycle drifts a day or two against the calendar. Roughly every 11 years — depending on which weekday your payday falls and where leap days land — that drift pushes a 27th fortnightly payday inside a single financial year. Your salary doesn't change, but that year's gross earnings are one fortnight higher: on a $80,000 salary, $83,077 instead of $80,000.

The tax catch: the ATO's fortnightly withholding rates are calibrated to 26 pays a year. Receive 27 and the standard per-fortnight withholding can come up short at tax time, so the ATO suggests asking payroll to withhold a little extra each fortnight in those years — the amounts are published alongside the fortnightly tax table. The calculator above shows your annual gross and net at both 26 and 27 paydays so the difference isn't a surprise.

Fortnightly pay and monthly bills don't line up: 26 paydays against 12 billing months means most months contain two paydays, but two months each year — three in a 27-payday year — contain a third. A fortnightly budget built on two pays a month treats those third pays as a buffer — an approach that absorbs the timing drift instead of fighting it. A useful rule of thumb: a monthly bill costs 12/26ths (about 46%) of its amount per fortnight, not half.

The fortnightly take-home pay guide covers the cycle mechanics in depth — why a fortnight isn't half a month, and how the fortnightly line appears on a payslip — and the budget planner turns your net fortnightly figure into a full allocation. For part-time or part-year work, the pro rata salary calculator scales the salary before you bring it here.
