Should I use gross or take-home income?

Use monthly take-home income for day-to-day budgeting. If payroll deductions already fund retirement or health insurance, keep that in mind when interpreting the result.

What is the 50/30/20 budget?

It is a guideline that allocates about 50% of take-home income to needs, 30% to wants, and 20% to savings or debt repayment.

What if my expenses are not monthly?

Convert annual, quarterly or irregular expenses into a monthly estimate so the budget includes them before they arrive.

Monthly budget from income and expenses

English budget-calculator intent is usually practical household planning: enter monthly income, list recurring expenses, see the surplus or deficit, and compare the result with a simple guideline such as 50/30/20.

Monthly income after taxes and deductions.
Recurring expenses such as housing, food, transportation and utilities.
Monthly surplus or deficit.
Savings rate and expense breakdown.
A 50/30/20 comparison for needs, wants, and savings or debt repayment.

Planning guide only

The 50/30/20 rule is a guideline, not a requirement. Housing costs, debt, family size, location and irregular income can make a different budget more realistic.

Budget formulas

S u r pl u s = M o n t h l y in co m e - M o n t h l y e x p e n ses

S a v in g s r a t e = \frac{S u r pl u s}{M o n t h l y in co m e} \times 100%

50/30/20 : N ee d s = 50%, W an t s = 30%, S a v in g s = 20%

What to review after calculating

Signal	What it can mean
Negative surplus	Expenses exceed income, so spending, income or debt payments need review.
Low savings rate	There may be little room for emergencies or long-term goals.
Large housing share	Housing can crowd out transportation, food, savings and debt payoff.
Irregular expenses	Annual bills, repairs and medical costs may need separate sinking funds.
