A 0–100 affordability score built from your real income, debts, savings, credit, and goals — not a marketing number from a lender. Three budget tiers (Conservative, Balanced, Stretch) tell you exactly what you can afford without wrecking your life.

Conservative

23.8% front-end DTI (28% × 0.85) — your stress-test budget

Balanced

28% front-end DTI — your realistic budget

Stretch

30.8% front-end DTI (28% × 1.10) — your ceiling

How the score is calculated

Your NestCost Score is a weighted composite of four pillars, each scored 0–100, then blended with a soft-min step so a weak link is never hidden by a strong average:

30%Affordability

Debt burden — how your housing payment and debts balance against your income, adjusted for your location's cost-of-living.

25%Credit

Score-based borrowing power — determines which loans you qualify for and your rate, with history, utilisation and late-payment modifiers.

25%Cash Buffer

Liquidity months + closing-cash coverage — whether your savings cover the down payment and closing costs with reserve left over.

20%Debt Health

Back-end debt-to-income ratio — the sustainability of your total monthly obligations against gross income.
