Budget Calculator

Plan your monthly budget with the 50-30-20 rule and track spending.

About the Budget Calculator

A monthly budget is the most powerful financial tool most Indians never actually use. Most people have a vague sense of their salary and a vague sense that they spend too much - but no clarity on where the money actually goes. One month of careful tracking typically reveals 10-15% of income disappearing into things the person does not consciously value: impulse deliveries, unused subscriptions, small daily habits that add up silently. That money, redirected into investments, can mean the difference between retiring at 55 and working until 65.

The 50/30/20 rule is the simplest starting framework: allocate 50% of take-home income to needs (rent, groceries, utilities, EMIs), 30% to wants (dining, entertainment, shopping), and 20% to savings and investments. It is not a rigid law - someone paying ₹30,000 rent on a ₹60,000 salary cannot hit the 50% needs target - but it is a diagnostic tool. If your needs alone consume 70% of income, you know immediately that either income needs to rise or a housing decision needs revisiting.

This calculator lets you enter your actual monthly expenses across all categories, see exactly how your split compares to the 50/30/20 targets, and add custom categories for anything the defaults do not cover. Every rupee is accounted for, and the savings rate updates instantly as you adjust any category - making it easy to see the real cost of lifestyle decisions in terms of lost savings.

50/30/20 Budget Framework

Needs (50%) + Wants (30%) + Savings (20%) = 100% of take-home income

Needs: rent, groceries, utilities, healthcare, minimum EMIs - expenses you cannot cut without major lifestyle disruption · Wants: dining out, entertainment, shopping, subscriptions, travel - expenses that improve quality of life but are discretionary · Savings: emergency fund contributions, SIPs, PPF/NPS deposits, extra loan prepayments · Savings Rate = (Income - Total Expenses) / Income × 100 · Monthly Savings = Take-Home Income - Total Expenses

Worked Example

Monthly take-home salary of ₹80,000 in a metro city

Monthly income (take-home):₹80,000
Needs: Rent + Groceries + Transport + Utilities + Healthcare:₹38,000 (47.5%)
Wants: Dining + Entertainment + Shopping:₹14,000 (17.5%)
EMI (home loan):₹8,000 (10%)

Total expenses = ₹60,000 · Monthly savings = ₹20,000 · Savings rate = 25% (above the 20% target) · ₹20,000/month invested at 12% for 20 years = ₹1.99 crore · Cutting just the dining + entertainment to ₹10,000 frees up ₹4,000 more per month - worth an extra ₹40 lakh over 20 years at 12%

Tips & Insights

  • 1

    Track actual expenses for 30 days before setting targets - most people underestimate their food and shopping spend by 30-40%.

  • 2

    Pay yourself first: set up an auto-debit SIP on the 1st or 2nd of the month so savings leave before you can spend them.

  • 3

    Subscriptions are the silent budget killer. OTT platforms, gym memberships, app subscriptions - audit them every 3 months and cancel anything unused in the last 30 days.

  • 4

    EMI burden should ideally stay below 35-40% of take-home income. Above that, prepayment of the highest-rate loan becomes the top financial priority.

  • 5

    The 50/30/20 rule needs adaptation for Indian metros. A ₹25,000 rent on a ₹60,000 salary makes the 50% needs target impossible - in that case, target 10-15% savings first and increase annually as income grows.

  • 6

    Food delivery apps (Swiggy, Zomato) are the single biggest wants budget leak for Indian urban professionals. Tracking app spend for one month is usually a wake-up call.

  • 7

    Build a 3-6 month emergency fund before aggressively investing. Without it, any unexpected expense (medical, job loss) forces you to break long-term investments at the worst time.

  • 8

    Zero-based budgeting - where every rupee of income is assigned a job before the month starts - works better than percentage targets for people with irregular or variable income.

Why this matters for you

India's household savings rate declined from around 25% of GDP in 2012 to under 19% in recent years, even as incomes rose. The gap is not explained by poverty - it is explained by lifestyle inflation and the explosion of consumer credit. Buy-now-pay-later, easy personal loans, and EMI-on-everything have made it trivially easy to spend beyond income. A budget does not restrict you; it shows you exactly what you are trading away with each spending decision. The compounding math makes budgeting urgency clear. An extra ₹5,000/month saved from age 28 instead of age 33 - just a 5-year difference in start date - produces roughly ₹70-80 lakh more in retirement corpus at 12% returns. That ₹5,000 is often sitting in subscriptions, food delivery, and impulse purchases. The budget calculator makes that invisible money visible. For Indian families specifically, a budget also serves as protection against financial emergencies that derail otherwise solid plans. Medical costs, job transitions, and family obligations can wipe out years of savings if there is no buffer. The emergency fund category in the savings bucket is not optional - it is the foundation that lets every other financial goal survive contact with real life.
