Monthly fixed costs calculator
Your regular bills added up per week, fortnight, month and year, whatever cycle each one is paid on.
To compare bills paid on different cycles, convert each to a yearly amount (weekly × 52, fortnightly × 26, monthly × 12, quarterly × 4), add them up, then divide by the period you want. The example bills below total $2,735.00 a month ($631.15 a week, $32,820.00 a year). Replace them with your own bills.

Compared with your pay (optional)
Good to know
- A month averages 52 ÷ 12 ≈ 4.33 weeks, so a weekly bill × 4 understates the monthly cost.
- Quarterly bills such as energy vary by season; using the average of the last four bills gives a steadier figure.
