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%

50% — Needs

Rent, groceries, transport, electricity, phone recharges, fees — the things you genuinely cannot skip.

30%

30% — Wants

Eating out, movies, subscriptions, shopping, trips — the things that make life enjoyable but flexible.

20%

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

  1. 1Know your monthly Money In — salary, stipend, freelance, everything.
  2. 2Move 20% to savings the day money arrives, before any spending.
  3. 3Cover your needs from the rest, then enjoy wants without guilt.
  4. 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.

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.
