How much should I save from my salary every month?

The question "how much to save from salary" is the most common in personal finance, and the one with the worst standard answer on the Brazilian internet: "20%, 50/30/20 rule". The number is not wrong. It is incomplete.

The 50/30/20 rule (and where it fails in Brazil)

American origin: 50% essential fixed costs, 30% variable expenses, 20% savings and debts. It works reasonably well in an economy with 2-3% annual inflation and housing costs of 25% of income.

In Brazil in 2026, with rent above 35% of income in capitals and credit card interest above 350% per year, the original rule distorts. For most salaried Brazilians, the realistic version is 60/25/15.

Practical matrix by life stage

SituationRecommended percentage
No reserve, with credit card debt5-10% for minimum reserve + everything left for debt
No reserve, no debt10-15% until reaching 1 month of fixed costs
Reserve between 1 and 3 months15-20%
Reserve above 3 months20-30% redirected to investment
On short-term goal (12-24 months)25-35% during the goal cycle

How to start when the budget is tight

If you can’t set aside 10% today, set aside 3%. The psychological effect of having "any reserve" far outweighs the mathematical effect of "waiting until you can save 20%". Start without guilt.

Common mistakes when deciding how much to save

  • Setting 25% right away without adjusting fixed costs. Result: debt at the end of the month.
  • Waiting to "have more money" to start. You won’t have it.
  • Confusing reserve (liquid, safe) with investment (may have risk and term).
  • Trying to save before tackling credit card revolving debt (interest higher than any yield).
