How it works

30% rule: rent ≤ 30% of gross monthly income. 3× rule: landlords require gross monthly ≥ 3× rent. Debt-adjusted deducts existing monthly debt from the 30% figure.

Frequently asked questions

Are these calculators private?

Yes — all computation happens in your browser. We don't store the values you enter.

What's the 50/30/20 budget?

50% needs, 30% wants, 20% savings & debt — a simple budgeting starting point.

How is net worth different from income?

Income is what you earn; net worth is what you own minus what you owe. Build net worth by keeping the gap between income and spending positive.

What's a FI number?

The portfolio size at which 4%/yr withdrawals indefinitely cover your annual expenses — i.e., 25× expenses.

Should I always take the higher-salary job?

Not always. Net of cost of living, taxes, commute, and benefits, the smaller salary sometimes wins.
