Budget Calculator

Use this Budget Calculator to compare your income and expenses for a monthly or yearly period. It estimates your remaining balance, savings rate, expense ratio, and overall budget status.

Budget Calculation Method

The calculator converts income and expenses to the selected monthly or yearly period before comparing them.

Total income = main income + other income

Total expenses = sum of all entered expenses

Remaining balance = total income − total expenses

Savings rate = (remaining balance ÷ total income) × 100

Expense ratio = (total expenses ÷ total income) × 100

A positive remaining balance means income exceeds the expenses entered. A negative balance means the listed expenses exceed income.

Example

Suppose your monthly income is $4,200 and your regular monthly expenses total $2,600.

Remaining balance = $4,200 − $2,600 = $1,600

Savings rate = ($1,600 ÷ $4,200) × 100 ≈ 38.10%

Expense ratio = ($2,600 ÷ $4,200) × 100 ≈ 61.90%

The budget therefore has a $1,600 positive balance before any expenses or savings that were not entered.

Important Notes

• For household budgeting, using after-tax or take-home income usually gives a more realistic picture of money available to spend.
• The calculated savings rate represents money left after the expenses entered. It is only actual savings if that money is saved.
• Include irregular expenses such as insurance, repairs, annual fees, medical costs, gifts, and seasonal bills when relevant.
• Weekly, monthly, and yearly amounts are converted to a common budget period, so actual cash-flow timing may still differ.
• The calculator does not automatically include taxes, payroll deductions, debt interest, emergencies, or unexpected expenses.
• Use actual spending records when possible rather than relying only on estimates.
