About the Budget Calculator

A budget answers one question: where does the money go? This budget calculator takes your monthly take-home income and a list of expense categories — housing, groceries, transport, utilities, entertainment and anything else you add — and instantly shows whether you run a surplus or a deficit, your savings rate, and each category's share of income.

The key numbers: surplus = income − total expenses, and savings rate = surplus ÷ income × 100. Earning 150,000 a month and spending 120,000 leaves a 30,000 surplus — a 20% savings rate, which happens to match the popular 50/30/20 guideline (roughly 50% of income for needs, 30% for wants, 20% saved). The category table makes it obvious when one line — usually rent or food — is eating more than its share.

Households tracking rising prices in Pakistan and India, students managing hostel allowances, and anyone building a first emergency fund can add or remove categories freely. Nothing about your finances leaves your browser.

Frequently Asked Questions

How do I calculate my savings rate?

Savings rate = (income − expenses) ÷ income × 100. With 150,000 income and 120,000 of expenses, you save 30,000, a 20% savings rate. Financial planners commonly suggest aiming for at least 20%, though any consistent positive rate beats none.

What is the 50/30/20 budget rule?

Allocate about 50% of take-home income to needs (rent, food, utilities, transport), 30% to wants (eating out, entertainment, shopping) and 20% to savings and debt repayment. On 150,000/month that is 75,000 needs, 45,000 wants and 30,000 saved. In high-rent cities the needs share often runs higher — treat the rule as a compass, not a law.

What percentage of income should rent be?

The common guideline is 25–30% of take-home pay. Paying 50,000 rent on 150,000 income is 33% — slightly above the guideline, worth watching. The category table in this calculator shows the exact percentage so you can compare against the benchmark.

What should I do if my budget shows a deficit?

A deficit means expenses exceed income and the gap is being covered by debt or savings. Attack the biggest lines first — housing, food and transport typically account for 60–70% of spending, so a 10% cut there beats eliminating small treats. The percentage column shows exactly which categories dominate.

Should I budget with gross or take-home income?

Take-home (after tax and deductions) — it is the money actually available to allocate. If your salary is 180,000 gross but 155,000 lands in your account, budget against 155,000. Benchmarks like 50/30/20 and the 30% rent rule are also expressed against take-home pay.
