50/30/20 is a starting point, not a rule. If needs take more than half, that's common in high-cost areas; adjust the split to fit.

What to do with the result

  • Needs over 50%? Look at the big three first: housing, transportation and childcare. One change there can matter more than many small ones.
  • Wants over 30%? Try a subscription check and a 24-hour rule for impulse buys.
  • Savings under 20%? Start with any amount and automate it on payday.
