Key Takeaways
- 50% needs, 30% wants, 20% savings — adjust ratios to your city and income
- Track spending for one month before creating a budget
- Automate savings on salary day so you never skip
What Is the 50/30/20 Rule?
Created by US Senator Elizabeth Warren, the 50/30/20 rule divides your after-tax income into three buckets: 50% for needs (rent, food, transport, insurance), 30% for wants (dining out, entertainment, shopping), and 20% for savings and debt repayment.
Step 1: Calculate Your After-Tax Income
Your in-hand salary after TDS deductions is your starting number. If you earn ₹60,000 in-hand per month, your split is: ₹30,000 needs, ₹18,000 wants, ₹12,000 savings.
Step 2: List Your Needs
Needs are non-negotiable expenses: rent/EMI, groceries, utilities (electricity, water, internet), transport to work, insurance premiums, minimum loan payments. If you cannot skip it without serious consequences, it is a need.
Step 3: Identify Your Wants
Wants are everything you enjoy but could live without: streaming subscriptions, dining out, new clothes beyond basics, gadgets, hobbies, weekend outings. This category is where most people overspend without realising.
Step 4: Automate Savings
Set up auto-debit on salary day for SIP investments, recurring deposits, or PPF contributions. When savings leave your account before you see the money, you adapt spending to what remains.
Indian City Adjustments
| City | Needs | Wants | Savings |
|---|---|---|---|
| Mumbai/Delhi (high rent) | 60% | 20% | 20% |
| Bangalore/Pune | 50% | 30% | 20% |
| Tier 2 cities | 40% | 30% | 30% |
Adjust the ratios based on your city's cost of living. In Mumbai, rent alone might consume 35-40% of your income — that is okay. Reduce the wants category to compensate, not savings.
Common Mistakes
- Classifying wants as needs (a ₹500/month gym is a want; health insurance is a need)
- Not tracking subscriptions (the average Indian has 4-5 recurring subscriptions they forget about)
- Skipping savings "just this month" — it always becomes a habit
