Budgeting basics
The 50/30/20 rule, explained simply
The 50/30/20 rule is one of the most popular budgeting methods in the world. It says: split your monthly income into three parts — 50% for needs, 30% for wants, and 20% for savings. No complicated spreadsheets, no accounting knowledge. Just three numbers to remember.
50% — Needs
Rent, groceries, transport, electricity, phone recharges, fees — the things you genuinely cannot skip.

30% — Wants
Eating out, movies, subscriptions, shopping, trips — the things that make life enjoyable but flexible.
₹9,000 of a ₹30,000 salary
20% — Savings
The part that belongs to your future — emergency fund, goals, and long-term security. Saved first, not last.

A real example: ₹30,000 monthly income
If you earn ₹30,000 a month, the rule suggests ₹15,000 for needs, ₹9,000 for wants and ₹6,000 for savings. Over one year, that 20% alone becomes ₹72,000 — a real emergency fund, built quietly, one month at a time.
How to actually follow it
- 1Know your monthly Money In — salary, stipend, freelance, everything.
- 2Move 20% to savings the day money arrives, before any spending.
- 3Cover your needs from the rest, then enjoy wants without guilt.
- 4At month end, review what actually happened and adjust next month.
Where First20 fits in
The hardest part of the 50/30/20 rule is the 20% — most people plan to save “whatever is left” at month end, and nothing is ever left. First20 flips that: the moment you record your income, it calculates your 20% savings target and treats it as saved first, not saved last.
- Enter your income — First20 instantly shows your 20% target
- Track what you actually saved and spent, in plain language
- Get a monthly review and Discipline Score that keeps the habit alive
Common questions
What if 20% feels impossible right now?
Start smaller — even 5% or 10% builds the habit. In First20 you can adjust your savings percentage in Settings, and increase it as your income grows. The habit matters more than the number.
Is the 50/30/20 rule realistic in India?
For many first earners living with family, needs are well under 50% — which means you can save even more than 20%. If rent takes a bigger share, adjust the wants portion first, never the savings.
Should savings include investments?
The 20% covers everything you set aside for the future. First20 helps you build the tracking habit; it does not give investment advice — for that, speak to a qualified advisor.
