Plan your monthly budget and see how your spending compares to the 50/30/20 rule.

💰 What is a Monthly Budget?

A monthly budget is a written plan that allocates your income to different spending categories before the month begins. Rather than discovering at the end of the month that you have spent more than you earned, a budget gives every rupee a purpose and ensures your financial decisions align with your actual priorities - whether that is paying off debt, building an emergency fund, saving for a home, or investing for retirement.

Budgeting does not mean deprivation. It means intentionality. Most people who start tracking their spending are surprised to find significant amounts leaking into categories they care little about - subscriptions they forgot to cancel, food deliveries that add up, impulse purchases. A budget shines a light on these patterns and gives you the choice to redirect that money toward things that matter.

The 50/30/20 rule is among the most practical budgeting frameworks. It divides your after-tax income into three buckets: 50% for needs (rent, groceries, utilities, essential transport, minimum debt payments), 30% for wants (dining out, entertainment, hobbies, upgrades), and 20% for savings and debt repayment beyond minimums. It is simple enough to remember and flexible enough to adapt.

For example, if your monthly take-home salary is ₹60,000, the 50/30/20 rule suggests ₹30,000 for needs, ₹18,000 for wants, and ₹12,000 for savings. If your rent alone is ₹18,000 and you live in Mumbai or Bengaluru, you may need to adjust the split - perhaps 60/20/20 - to reflect local cost realities without abandoning the savings discipline entirely.

This calculator lets you input your actual monthly income and eight expense categories, then compares your spending against the 50/30/20 targets with colour-coded indicators. Use it as a diagnostic tool: run it with your actual current numbers, see where you stand, then plan adjustments category by category to move toward your target allocation.

📐 Budget Formula

Savings Rate = (Savings ÷ Income) × 100

Total Expenses = Housing + Food + Transport + Utilities + Entertainment + Healthcare + Savings + Other

Remaining = Income − Total Expenses (positive = surplus, negative = deficit)

50/30/20 Needs Target = Income × 0.50 (Housing + Food + Transport + Utilities + Healthcare)

50/30/20 Wants Target = Income × 0.30 (Entertainment + Other)

50/30/20 Savings Target = Income × 0.20

The savings rate is the most critical metric in personal finance. A 20% savings rate means you could theoretically replace your current lifestyle after saving for 4 years for every 1 year of expenses - the foundation of financial independence planning. The 50/30/20 rule is a guideline; adjust it based on your income level, location, life stage, and goals.

💡 Example Calculations

Example 1 — Salaried Professional, ₹70,000/month

Income: ₹70,000 | Housing ₹18,000, Food ₹7,000, Transport ₹4,000, Utilities ₹2,500, Entertainment ₹6,000, Healthcare ₹2,000, Savings ₹14,000, Other ₹4,000

Total Expenses = 18,000 + 7,000 + 4,000 + 2,500 + 6,000 + 2,000 + 14,000 + 4,000 = ₹57,500

Remaining = 70,000 − 57,500 = ₹12,500 surplus

Savings Rate = (14,000 ÷ 70,000) × 100 = 20% — exactly on target

Needs (Housing+Food+Transport+Utilities+Healthcare) = ₹33,500 = 47.9% of income — under the 50% target ✓

Result: On track with 50/30/20. ₹12,500 surplus can go toward an emergency fund or additional investment.

Example 2 — Overspending Identified, ₹45,000/month

Income: ₹45,000 | Housing ₹16,000, Food ₹8,000, Transport ₹3,500, Utilities ₹2,000, Entertainment ₹8,000, Healthcare ₹1,000, Savings ₹3,000, Other ₹5,000

Total Expenses = ₹46,500 - already ₹1,500 over income

Savings Rate = 3,000 ÷ 45,000 = 6.7% - well below 20% target

Wants (Entertainment + Other) = ₹13,000 = 28.9% - close to the 30% cap but total is unsustainable

Fix: Reduce entertainment to ₹5,000 and other to ₹3,000, freeing ₹5,000 additional for savings. New savings rate = 17.8%.

Frequently Asked Questions

What is the 50/30/20 budgeting rule?+

The 50/30/20 rule is a simple budgeting framework popularised by Senator Elizabeth Warren in her book 'All Your Worth'. It suggests allocating 50% of your after-tax income to needs (housing, food, utilities, transport), 30% to wants (entertainment, dining out, subscriptions, hobbies), and 20% to savings and debt repayment. It is a starting point, not a rigid rule - high-cost cities may require more than 50% for needs.

How do I calculate my savings rate?+

Savings rate = (Monthly Savings ÷ Monthly Income) × 100. For example, if you earn ₹60,000 and save ₹12,000, your savings rate is 20%. Financial independence (FIRE) communities typically target savings rates of 40–60%, while the standard recommendation is a minimum of 20%. Even a 10% savings rate is far better than zero.

What counts as a 'need' vs a 'want' in budgeting?+

Needs are expenses you cannot reasonably live without: rent or mortgage, basic groceries, electricity, water, essential transport to work, minimum debt payments, and health insurance. Wants are discretionary: dining out, streaming services, gym memberships, vacations, and new gadgets. The distinction can be blurry - a smartphone is a need, but the latest flagship model is a want.

How much should I save each month?+

A common benchmark is saving at least 20% of your net income. At that rate, you build an emergency fund, contribute to retirement, and make progress toward financial goals simultaneously. If 20% feels impossible, start with whatever you can - even 5% - and increase by 1–2% every few months. The habit matters more than the exact amount in the early stages.

What is a realistic budget for someone earning ₹50,000 per month?+

At ₹50,000/month, the 50/30/20 split gives ₹25,000 for needs, ₹15,000 for wants, and ₹10,000 for savings. Needs allocation: rent ₹12,000–15,000 (if renting in a Tier-2 city), groceries ₹4,000–5,000, transport ₹2,000–3,000, utilities ₹1,500–2,000. Wants: dining/entertainment ₹5,000–8,000, subscriptions ₹1,000–2,000. Savings: SIP ₹5,000–7,000, emergency fund ₹3,000–5,000. High-rent cities may need adjustment.

Is the 50/30/20 rule realistic in India's metros?+

The 50/30/20 rule (50% needs, 30% wants, 20% savings) is a useful starting framework but can be challenging in high-cost cities like Mumbai or Delhi where rent alone can consume 25-35% of income. Adjust the split to your city and income level - a more realistic framework for many Indian metro residents is 60/20/20. The key principle is to always pay yourself first (set aside savings before discretionary spending) regardless of the split you choose.

How do I reduce my monthly expenses effectively?+

Start by categorising every expense into needs (rent, groceries, utilities, EMIs), wants (dining out, subscriptions, shopping), and savings. Identify your top 3 discretionary categories by spend. Small consistent reductions compound significantly: cutting 3,000/month from dining saves 36,000/year. For fixed costs, renegotiate: call your internet provider, review insurance premiums annually, and consolidate high-interest debt. Automate savings on salary day so discretionary spending only happens from what remains.

What is zero-based budgeting and how is it different from the 50/30/20 rule?+

Zero-based budgeting assigns every rupee of income to a specific category until Income minus Expenses = 0. Every expense must be justified each month. The 50/30/20 rule is simpler: 50% needs, 30% wants, 20% savings/debt - no detailed line items required. Zero-based gives more control; 50/30/20 is easier to maintain long-term.
