How to Make a Monthly Budget That Actually Works (The 50/30/20 Rule)

Step 2: Sort your spending into the three buckets

Needs (the 50%)

Needs are expenses you'd still face even in a difficult month:

• Rent or home loan EMI
• Groceries, electricity, water, basic mobile/internet
• Transport to work and essential medical costs
• Minimum loan repayments

Be honest here. A premium OTT bundle is not a need just because you use it daily.

Wants (the 30%)

Wants are the choices that make life pleasant: eating out, movies, the upgraded phone, weekend trips, that extra streaming subscription. There is nothing wrong with wants — they're built into the rule on purpose. The goal is to enjoy them within a limit.

Savings and debt (the 20%)

This bucket does double duty: building your future and clearing the past. It covers your emergency fund, SIPs or other investments, and any extra repayment on high-interest loans beyond the minimum. If you carry credit-card debt, prioritise that first — paying off 36% interest is a guaranteed return no investment can match.

Step 3: Adjust the ratios to your reality

The numbers are guidelines, not commandments. In many Indian metros, rent alone can push needs past 50%. In that case:

• Temporarily run something like 60/20/20 or 60/25/15
• Protect the savings share even if it shrinks
• Treat improving the ratio as a goal as your income rises

A young earner living with family might flip the script entirely and save 35–40%. Use the structure; bend the percentages.
