Checklist
| Situation | Useful tools | Avoid |
|---|---|---|
| Buying a home | Affordability, P&I, PITI | Ignoring taxes/insurance/MI |
| Paycheck planning | Take-home, FICA, Hourly↔salary | Treating effective rate as marginal bracket |
| Debt reduction | Card payoff, Snowball/avalanche, DTI | Paying only interest without a plan |
Worked examples
Example A — 30-year fixed shopping with Refinance Break-Even Calculator
Price $400,000, 20% down, 6.5% APR. Run P&I here, then PITI with local tax and insurance quotes.
Action: Check DTI and affordability before higher price bands.
Example B — FHA vs conventional sketch
3.5% down FHA path on FHA vs PMI path on PMI. Include closing costs.
Action: Prefer figures on your official Loan Estimate when they differ.
Example C — Extra payment or biweekly
Model extra principal on extra payment or biweekly after you know base P&I.
Action: Confirm servicer application rules before changing payment habits.
Common mistakes
-
Treating P&I as the full housing payment
Taxes, insurance, HOA, and MI can add a large escrow. Cross-check PITI.
-
Using outdated FICA wage base or MIP rates
Enter current SSA wage base and HUD MIP schedules — defaults are orientation only.
-
Comparing loans on monthly payment alone
Longer terms lower payment but can raise total interest. Use loan comparison.
-
Confusing effective tax rate with marginal bracket
Use effective tax rate when pay and tax tools interact with housing budgets.
-
Skipping official disclosures
When a Loan Estimate or lender quote differs from this site, prefer the official document.
Special situations
- Self-employed / 1099: income documentation and SE tax change both mortgage underwriting and tax set-asides — contractor set-aside + DTI.
- High LTV purchase: model FHA MIP vs conventional PMI and cash for down payment.
- Variable income: be conservative on affordability and build emergency fund runway first.
- Short horizon moves: rent vs buy and refinance break-even matter more than maximum loan size.
