Setting up a payday budget: a worked example
Setting up a payday budget takes one sitting and produces a single number: the amount you move aside each payday so every bill is covered. This is that process done end to end for a hypothetical household paid fortnightly, with eleven real bills and one savings goal, including the checks worth doing before you trust the result.
Everything below is a worked example rather than a recommendation. The figures are invented; the method is the same one described in the payday budgeting method.
Step 1: the income line
Take-home pay, the number that actually lands, not the gross. For this example it's $2,100 a fortnight, paid every second Thursday.
On variable income, use the lowest fortnight you'd realistically expect rather than an average. An average means roughly half your fortnights come in under budget, which is the wrong half to be surprised by.
Step 2: list every bill with its real frequency
The trap here is converting as you go, because that's where the mistakes get made. Write each bill at the amount and frequency it's actually charged, then convert everything in one pass. Mixed units are where the errors come from.
Eleven bills, as charged
- Rent, fortnightly $520.00
- Car loan, fortnightly $180.00
- Insurance, monthly $130.00
- Phone, monthly $45.00
- Internet, monthly $85.00
- Streaming, monthly $15.99
- Gym, monthly $62.00
- Power, quarterly $340.00
- Water, quarterly $260.00
- Car registration, yearly $890.00
- Contents insurance, yearly $420.00
Two are already fortnightly and paid directly. The other nine need converting.
Step 3: convert everything to one payday
Yearly cost divided by 26. Monthly bills multiply by 12 first, quarterly by 4.
The nine converted bills
- Insurance, $1,560 a year $60.00
- Phone, $540 a year $20.77
- Internet, $1,020 a year $39.23
- Streaming, $191.88 a year $7.38
- Gym, $744 a year $28.62
- Power, $1,360 a year $52.31
- Water, $1,040 a year $40.00
- Car registration, $890 a year $34.23
- Contents insurance, $420 a year $16.15
- Set aside each fortnight $298.69
$298.69 covers $7,765.88 of bills a year that do not arrive fortnightly.
Step 4: add the savings goal
A goal is the same sum run backwards: target divided by the number of paydays you want to take. It competes directly with what is left over each payday, which is the honest way to size it.
A $2,000 buffer over a year is $2,000 / 26, which is $76.92 a fortnight. Over two years it's $38.46. The point of writing it as a per-payday figure is that it becomes comparable with everything else, and you can see immediately what it displaces.
Step 5: the subtraction
One fortnight, complete
- Take-home pay $2,100.00
- Rent and car loan, paid directly $700.00
- Moved to the bills account $298.69
- Moved to the savings goal $76.92
- Left in the everyday account $1,024.39
$1,024.39 covers groceries, fuel and everything discretionary for a fortnight. Worked example, not a recommendation.
Step 6: the checks worth doing
Three of them, and they don't take a minute between them.
Multiply the set-aside back out. $298.69 x 26 = $7,765.94, which should match your yearly total for those bills within a few cents. If it is out by more, something's been converted at the wrong frequency.
Then look at the leftover honestly. Groceries and fuel come out of it. If $1,024 a fortnight has to cover $400 of groceries and $120 of fuel, the genuinely discretionary figure is closer to $500, and that's the number to sanity-check against how you actually live.
Last, check what's due soon. A $890 registration due in two months has had about four set-asides against it, roughly $137. That gap is the ramp-up, it's normal, and it's better known now than discovered later. Smoothing big bills covers both ways of handling it.
Step 7: start on a payday, not today
The last step is the one I got wrong myself. If you set this up mid-cycle, some of this fortnight's bills have already come out and some of the money has already gone, so nothing reconciles and you spend weeks wondering why.
Either start on your next payday, so you have one clean cycle to measure from, or write down what's already sitting in each account as an opening balance so the totals match your real bank from day one. I did neither, and my figures were quietly wrong for nine fortnights.
What this looks like ongoing
The setup above is all the work there is. After that it's one transfer of $298.69 and one of $76.92 each payday, and spending what's left without doing sums.
It only changes when a bill does, which is a two-minute edit and a new total. Once a year is worth a proper review, mostly because power and water drift.
Questions people ask
How long does it take to set up a payday budget?
One sitting, mostly spent listing bills. The conversion is one division per bill, and the ongoing commitment afterwards is a couple of transfers each payday.
What if my income changes every pay?
Base the calculation on the lowest fortnight you would realistically expect rather than an average. An average means roughly half your fortnights come in under budget. Anything above the baseline is then genuinely surplus.
How do I turn a savings goal into a per-payday amount?
Divide the target by the number of paydays you want to take. A $2,000 goal over a year of fortnightly pay is $2,000 divided by 26, which is $76.92 a fortnight. Writing it per payday makes it comparable with your bills.
How do I check the set-aside figure is right?
Multiply it back out by your number of paydays and compare it with the yearly total of those bills. The two should match within a few cents. A larger gap usually means a bill was converted at the wrong frequency.
Should I start today or wait for my next payday?
Starting on your next payday gives you one clean cycle to measure from. If you start mid-cycle, record what is already sitting in each account as an opening balance so the running totals match your bank from the outset.
