Budget by pay period, not by month

Most budgets are built around the calendar month. Most paychecks are not. If you are paid every two weeks, a monthly budget misleads you twice a year and makes some weeks feel tighter than they really are.

Why monthly budgets drift

A biweekly schedule means 26 paychecks a year, not 24. Ten months give you two paychecks, and two months give you three. A weekly schedule gives you 52, and a twice-a-month schedule gives you 24.

Here is what that does to a $1,500 paycheck:

• The "monthly average" is $1,500 × 26 ÷ 12 = $3,250.
• In a typical month you actually receive $3,000.
• In the two three-paycheck months you receive $4,500.

If you plan around $3,250, you are $250 short in most months, and you will not notice until the account is low.

Bills have the same problem in reverse. Rent lands on the 1st, car insurance on the 15th, and neither cares which paycheck is supposed to cover it.

The pay-period approach

Instead of asking "what does my month look like?", ask "what does each paycheck have to cover?"

1. List your paycheck dates for the next few months.
2. Assign each bill to the paycheck that arrives before its due date.
3. Give every paycheck its own envelopes for groceries, gas, wants, debt payments, and savings.
4. Treat three-paycheck months as extras. Send them to debt or savings first, not to a higher lifestyle.

A worked example

Two $1,500 paychecks, with the bills split by due date:

	Paycheck A	Paycheck B
Bills	$965 (rent $900, internet $65)	$227 (car insurance $142, phone $85)
Groceries	$200	$200
Gas	$80	$80
Wants	$75	$75
Debt payment	$120	$120
Savings	$60	$60
Left unassigned	$0	$738

Paycheck A is fully spoken for. Paycheck B has $738 of slack. That is not free money. It is a decision you should make on purpose: an extra debt payment, a fund for annual bills, or savings. A monthly view hides this completely.

Common mistakes

• Averaging the paychecks. It feels tidy and it is wrong in most months.
• Putting every bill on the first paycheck of the month. It makes one paycheck look broke and the other look rich.
• Spending the third paycheck. It is the easiest place to make real progress on debt.

Where Finance Command fits

Finance Command's envelopes work this way. Each bill is placed in the pay period it falls in, and each envelope shows what is left of the current paycheck. You can see what is still safe to spend before the next one arrives.

This is general information, not financial advice. Your own situation may call for a different approach.
