How to budget on a biweekly paycheck

Why biweekly is genuinely harder

Being paid every two weeks is not a slightly different version of being paid monthly. It is a different rhythm, and three things follow from that.

26 paychecks, 12 months. Two weeks does not divide into a month. Some months hold two paychecks, some hold three, and which is which changes every year.

Bills move relative to your pay. Rent is due on the 1st. Your paycheck lands on a Friday. In January that Friday might be the 3rd, in February the 14th. The gap between “money in” and “money out” changes every single month, and the tight weeks are the ones where a bill lands just before a paycheck rather than just after.

Two months a year have three paychecks. A monthly budget shows those as an unusually good month. They are actually the two best opportunities you get all year, and treating them as a surplus is how they disappear.

The standard advice is to divide your annual pay by twelve and budget that. It is arithmetically correct and practically useless: the average is not what is in your account on the 9th.

The method: budget the pay period, not the month

Stop asking “what is my monthly budget” and start asking ”what has to come out of this paycheck, and what is left.”

Each pay period is its own small budget. Two weeks of bills, one paycheck, one answer.

Step 1: list your bills with the date each one is due

Not the amount per month. The date. Rent on the 1st, car payment on the 18th, electricity around the 27th.

Step 2: write down your next six paydays

Actual dates. If you are paid on alternate Fridays, put the six real Fridays on paper. This is the step people skip and it is the one that makes the rest work.

Step 3: assign each bill to the paycheck that has to cover it

Work down your paydays and put each bill against the last payday before it is due. A bill due on the 18th is covered by the paycheck on the 15th, not the one on the 29th.

You will find this comes out lopsided, and that is the discovery. Most people find one paycheck a month carrying rent and very little else, and the other carrying eight small bills. That imbalance was always there. You were just absorbing it by feeling short in some weeks and flush in others.

Step 4: even it out, once

Now that you can see the lopsidedness, fix it rather than re-living it. Two ways:

• Move a due date. Most utilities, phone companies and card issuers will change your due date if you ask. This is the single most effective thing in this article and it costs one phone call.
• Hold money across a pay period. Put half the rent aside from the light paycheck so the heavy one is survivable. This is what a buffer is for.

Step 5: plan the three-paycheck months before they arrive

Look at your six dates. Find the month with three paydays. That third paycheck has no bills assigned to it, because your bills are monthly and they are already covered.

Decide now what it is for. An extra card payment, the emergency fund, the thing you have been putting off. Decide in advance, because a paycheck with no plan attached is a paycheck that gets absorbed.

A worked example

Someone paid $1,900 every other Friday, with these bills:

Total monthly outgoings: $2,087. Monthly income averages about $4,117. On a monthly view this looks comfortable, with roughly $2,000 spare.

Now split it by pay period. Say paydays fall on the 5th and the 19th:

Paycheck landing the 5th covers everything due before the 19th. That is rent at $1,250, and nothing else. Left: $650.

Paycheck landing the 19th covers everything due before the next payday: car payment, insurance, student loan, internet, phone, electric. That is $837. Left: $1,063.

The monthly view said $2,000 spare. The real picture is $650 in one fortnight and $1,063 in the other, and the first fortnight is when groceries and petrol have to come out of $650.

Nothing is wrong with these finances. What was wrong was the frame.

Do this with a calendar

The step that makes this concrete is seeing your paydays and your bills on the same calendar, which is awkward on paper because your paydays move.

Take one real payday and count forward in fourteens for a year. Two of those months will catch three paydays; mark them, because they are the two that quietly rescue the other ten.

Doing it every payday without the spreadsheet

The method above works on paper and plenty of people run it that way for years.

What paper does not do is keep itself current. Balances change, a bill moves, you get paid a day late, and the plan has to be redone.

Cashrou is built on exactly this method. You tell it your pay rhythm, it works out your real paydays, and each payday it shows the bills due before the next one and what is left after them. You tick things off as they happen and the figure updates. It never connects to your bank, so the balances are the ones you confirm.

Seven days free, and one payday is enough to know whether it suits you.

The short version

• Budget the pay period, not the month
• Write down your real paydays before anything else
• Assign each bill to the paycheck that must cover it
• Move a due date if one paycheck is carrying too much
• Decide what the third paycheck is for before it arrives
