| Scenario | Income | Housing | Debts | Savings | Emergency | Score | Rating |
|---|---|---|---|---|---|---|---|
| Balanced budget | $7,000 | $2,520 | $700 | $700 | $15,000 | 82 | Good |
| High housing load | $6,000 | $2,700 | $750 | $300 | $4,000 | 45 | Risky |
| Strong buffer | $8,500 | $2,200 | $600 | $1,200 | $25,000 | 92 | Excellent |
Your score starts by comparing total monthly income to fixed and essential outflows. Income is modeled as gross income plus stable other income, then converted into a planning baseline. Residual buffer is computed as Income − (Core Costs + Savings). A residual near 0 means the plan is tight, while a residual above 10% of income indicates flexibility.
Housing costs include payment, property tax, home insurance, HOA, and utilities. The housing ratio equals Housing Costs ÷ Income. The scoring awards the most points at or below 25%, stays strong through 30%, weakens beyond 35%, and flags stress near 40% or higher. A guideline cap is shown at 28%, which many planners use as a conservative target for cash flow.
Debt ratio equals (Housing Costs + Debt Payments) ÷ Income, a simplified DTI view. The score rewards ratios at or below 15% most, remains solid through 25%, turns cautious beyond 35%, and becomes high‑risk near 45%+. The table estimates headroom using a 36% total debt guideline, separating housing (28%) from other debts (the remainder) to show where reductions matter.
Savings rate is Savings Goal ÷ Income, so a $500 goal on $5,000 income equals 10%. A 20% savings rate earns maximum points, 10% earns strong points, and 5% is treated as a starter level for building momentum. If your residual is negative, the score will usually drop because savings targets are not supported by cash flow, even when the percentage looks disciplined. Adjust goals to match headroom first.
Emergency coverage equals Emergency Fund ÷ Core Costs, measured in months. Six months earns full points, three months earns strong points, and one month earns starter points. For example, a $9,000 fund against $3,000 core costs equals 3.0 months. Higher coverage improves resilience against income disruption, reduces reliance on new debt when expenses spike, and can stabilize your overall score even if ratios are average.
It summarizes housing ratio, debt ratio, savings rate, and emergency coverage into a 0–100 score. Higher scores usually mean your monthly plan has more cushion and lower risk of payment strain.
No. Lenders calculate DTI using specific debt definitions and documentation. This tool uses a planning DTI based on the numbers you enter to help you stress‑test a monthly budget.
Enter monthly amounts. If a bill is annual, divide by 12 before entering it. Keep income and expenses in the same time period to avoid distorted ratios.
The score uses common planning targets: about 28% for housing and 36% for total debt, plus savings and emergency‑fund benchmarks. They are reference points, not universal rules.
High income can still produce a low score if housing, debts, or essentials consume most of it. Check ratios and residual income; reducing fixed payments often improves the score faster than increasing savings targets.
Start with one lever: lower housing costs, refinance or pay down high‑payment debt, reduce essentials, or build a one‑month emergency buffer. Even small changes can shift ratios and add points.
