How do you budget when you're paid fortnightly but bills are monthly?
Updated 2026-10-15 · Australia
Turn every bill into a per-pay amount and set that aside each payday. For a monthly bill, multiply by 12 and divide by 26. Rent of $2,100 a month becomes $969.23 a fortnight. Quarterly bills: × 4 ÷ 26. Yearly bills: ÷ 26. Then the two “extra” pays each year become a buffer, not a surprise.
Why monthly bills feel harder on fortnightly pay
There are 26 fortnights in a year but only 12 months, so most months contain two paydays and two months contain three. If you budget “two pays a month”, you under-count your income by two pays a year and the timing of bills never lines up.
The conversion table
| Bill is paid… | Per fortnight | Example |
|---|---|---|
| Weekly | × 2 | $190 groceries → $380 |
| Monthly | × 12 ÷ 26 | $90 phone → $41.54 |
| Quarterly | × 4 ÷ 26 | $420 power → $64.62 |
| Yearly | ÷ 26 | $850 car rego → $32.69 |
Which pay should cover rent?
Neither — that's the point. If you move the per-fortnight amount into a separate bills account every payday, the money is already there whenever the bill lands. Moneysmart recommends separate accounts for bills, spending and savings.
What to do with the third pay in a month
Because your bills account is funded per pay, the “third pay” months simply build a buffer in that account. Many people sweep any surplus to savings or an offset once a quarter.
Frequently asked questions
Is it ×26/12 or ×12/26?
Monthly to fortnightly is × 12 ÷ 26. Fortnightly to monthly is × 26 ÷ 12 (for example $2,850 a fortnight is $6,175 a month).
What if I'm paid weekly?
Use 52 instead of 26: monthly × 12 ÷ 52.
Do I need a spreadsheet?
No, but it saves the maths. Sorted Budget converts every bill to your pay cycle automatically.
