Finance & Business · pattern B, Repeating rows

A budget that reconciles against income.

List each expense line against a monthly income figure. The panel totals them, shows the largest line and reports the surplus or shortfall plainly.

Inputs

Monthly incomeTake-home.

Expense — row 1Per month — row 1

Expense — row 2Per month — row 2

Expense — row 3Per month — row 3

Expense — row 4Per month — row 4

Expense — row 5Per month — row 5

Expense — row 6Per month — row 6

The formula used

balance = income − Σ expenses

Enter every line as a monthly figure. Annual and quarterly costs divided down keeps the comparison honest and stops the third month surprising you.

Treat saving as a line, not a leftover.

Budgets that save whatever remains at the end of the month save nothing, because spending expands to fill the available balance. Listing savings as an expense line — as the default above does — is the single change that most reliably makes a budget work, and it also makes the trade-off against other lines explicit.

Questions about budget

What is the 50/30/20 rule?: A rough allocation: half to needs, 30% to wants, 20% to savings and debt repayment. Useful as a starting point and unrealistic in high-rent cities.
How much should go on rent?: Below a third of take-home is comfortable and often impossible. Above half, the rest of the budget has essentially no tolerance for anything unexpected.
Should I budget weekly or monthly?: Monthly matches most bills; weekly matches most food and transport spending. Doing both for the relevant lines is more accurate than forcing one period.

A calculator handles the arithmetic. It cannot teach you the method.

If the number is not the part you are stuck on, that is what the service is for — a specialist who explains the working, not just the answer.
