50/30/20 budget calculator
Enter monthly take-home income in any currency and optional essential expenses in the same currency. The calculator shows the 50/30/20 reference amounts and compares your entered essentials with the 50% guideline.
Calculate budget amounts
For general education only. No financial, tax or investment advice. Amounts are shown in the currency you enter.
What the three categories can include
Needs · 50% reference
Costs that are difficult to avoid, such as housing, basic utilities, groceries, transport needed for work, health costs and minimum debt payments. Some expenses can be partly essential and partly optional.
Wants · 30% reference
Discretionary spending, for example dining out, entertainment, optional subscriptions, travel and hobbies. Your circumstances may change how you classify a cost.
Savings and goals · 20% reference
Savings, emergency reserves, additional debt repayment and other financial goals. The calculator does not select accounts, investments or repayment strategies.
How the estimate works
The tool multiplies take-home income by 0.50, 0.30 and 0.20. If you enter essential costs, it divides that amount by take-home income to show its share. It does not classify expenses for you, assess debt affordability, include irregular costs or predict future income.
Frequently asked questions
Is 50/30/20 a rule everyone must follow?
No. It is one budgeting framework. Housing costs, family needs, income stability and local prices differ; use the percentages as a comparison, not a requirement.
Should I enter gross or take-home income?
Use the amount available to budget after taxes and required payroll deductions. If income varies, choose a representative monthly amount and account for irregular months separately.
What if essential expenses exceed 50%?
The comparison only shows that the entered amount is above the guideline. It does not mean you have failed or that a particular expense should be cut. Review your actual numbers and seek qualified local help if you need individual advice.
Does the calculator include minimum debt payments?
The framework generally places required minimum payments with needs and additional repayment in the savings/debt-goal portion. This tool does not assess interest, repayment order or whether a payment is affordable.
Sources and context
The U.S. Consumer Financial Protection Bureau presents a 50/30/20-style spending guideline; its educational material describes 50% for needs, 30% for wants and 20% for savings and debt payments. Elizabeth Warren and Amelia Warren Tyagi co-authored All Your Worth, a book associated with popularizing this framework. These sources provide context, not a universal financial standard.
