Budget Results
This calculator provides a simple budget estimate. Actual cash flow may differ because of irregular income, one-time expenses, taxes, loan payments, subscriptions, seasonal bills, and timing differences between when money is earned and spent.
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.
