50/30/20 Budget Calculator

The 50/30/20 rule is one of the simplest budgeting frameworks: spend 50% of your take-home pay on needs, 30% on wants, and put 20% towards savings and debt repayment. This calculator turns the rule into concrete rupee targets, then compares them with what you actually spend — so you get a clear diagnosis, a budget health estimate, and a short action plan, not just three percentages. It also offers India-aware modes (metro, high-savings, debt-recovery, low-income, custom) because rising rent and family costs make a strict 50% needs limit hard for many households.

In shortA 50/30/20 budget calculator divides your monthly take-home income into 50% for needs, 30% for wants, and 20% for savings or debt repayment. On ₹80,000 that is ₹40,000 needs, ₹24,000 wants and ₹16,000 savings. This page also compares your actual spending with the recommended split and gives a budget health estimate.

Net pay after tax and PF — the amount that reaches your bank account. Use take-home, not CTC.

Pick a split. Metro and low-income modes allow higher needs; high-savings and debt-recovery push more to the 20% bucket.

Good but needs tuning (80/100). Your needs are ₹4,000 above the recommended limit. Needs over target: review rent/EMI, utilities, groceries, transport and insurance first — fixed costs are harder to cut, so optimise those before lifestyle. At the recommended ₹16,000/month saved, that is ₹1,92,000 in a year and ₹9,60,000 over 5 years (before any investment returns). This is an educational estimate, not a credit score or financial advice.

What your result means

  • A negative gap on a bucket means you overshot it that month — Needs creeping past 50% is the most common culprit.
  • The 20% savings figure is a floor, not a ceiling; raise it whenever a salary hike lands before lifestyle catches up.
  • Apply the split to take-home pay, and in high-rent metros expect Needs to run above 50% — compensate by trimming Wants, not Savings.

How to use this calculator

  1. Enter your monthly take-home pay — net salary after tax and PF, not your CTC.
  2. Pick a budget rule. Use Metro or Low-income if rent and essentials run high; High-savings or Debt-recovery to push more to the 20% bucket; Custom to set your own ratio.
  3. Enter your actual needs, wants and savings to compare them against the targets.
  4. Read the budget health estimate and the biggest issue detected, then follow the action plan.
  5. Open “Advanced assumptions” to track separate debt repayment or set custom percentages.

The formula

For the selected mode: Needs = Income × needs%, Wants = Income × wants%, Savings/Debt = Income × savings%. Standard mode = 50% / 30% / 20%, which always totals 100% of take-home pay. Gap = actual − recommended (positive = over target). Custom ratios must total 100%.

Worked example

On a take-home income of ₹80,000 with the standard rule: needs target = ₹40,000, wants target = ₹24,000, savings/debt target = ₹16,000. Say your actual spending is ₹44,000 needs, ₹24,000 wants and ₹12,000 savings. Needs are ₹4,000 over target and savings ₹4,000 under, wants are on track, and nothing is unallocated — a budget health estimate of about 80/100 ("good but needs tuning"). The fix: hold savings at the target and pull the ₹4,000 from wants, not from your SIPs.

Methodology

Recommended targets = monthly take-home income × the ratio for the selected mode (Standard 50/30/20, Metro 60/20/20, High-savings 40/20/40, Debt-recovery 50/20/30, Low-income 65/15/20, or a custom ratio you set). Your actual needs, wants and the savings/debt bucket are compared against those targets to produce per-category gaps, a monthly surplus or shortfall, and a 0–100 budget-health estimate that starts at 100 and deducts points for needs/wants overspending, a savings shortfall, or spending above income (with a small reward for saving above target). Custom ratios are validated to total 100%. Every figure on the page — cards, comparison chart and table, diagnosis and example — comes from this one engine. It does not verify real bank data, model inflation, or assume investment returns.

Why results differ across calculators

  • High rent or a large home-loan EMI pushes needs well above 50% in metros.
  • Family responsibilities, school fees and medical costs raise the essentials floor.
  • Debt repayment may need a bigger bucket than 20% for a while.
  • Low or irregular/business income makes a strict percentage split harder to hold month to month.
  • City cost differences and an emergency-fund gap change how much should go to needs vs savings.

When to use it

  • Diagnosing whether your rent and lifestyle are out of proportion to your income.
  • Comparing the standard rule against a metro or high-savings split for your city.
  • Setting a first budget after a raise so the extra income is split deliberately.
  • Checking, before a big commitment, whether your savings target still survives.
