Methodology, Model Assumptions & Statutory Rules
SolveItCalculator strictly separates mathematical equations, baseline assumptions, current statutory rules, and general financial planning information.
1. Deterministic Calculator Math
Total monthly mortgage cost is PITI: Principal & Interest (Annuity formula) + Property Taxes (Annual / 12) + Homeowner Hazard Insurance (Annual / 12) + PMI (if LTV > 80%).
2. Model Assumptions
- Fixed-rate mortgage interest rate remains constant over 15, 20, or 30 years.
- Escrow property tax and insurance payments are based on user inputs without projected municipal assessment increases.
3. Current Statutory / Tax Rules
- Homeowners Protection Act of 1998 mandates automatic cancellation of borrower-paid PMI when principal balance reaches 78% of original property value (or borrower request at 80%).
- CFPB Qualified Mortgage (QM) standards generally cap total debt-to-income (DTI) ratio at 43% for prime underwriting.
4. Financial Information & Principles
- A 20% down payment eliminates PMI, saving $100–$300+ per month on conventional financing.
- A 15-year fixed mortgage typically offers a 0.50%–0.75% lower interest rate and cuts total interest costs by over 60% compared to a 30-year term.

Understanding PITI: Principal, Interest, Taxes, and Insurance
Complete breakdown of what makes up an escrowed monthly home mortgage payment.
Governing Formula
PITI = Principal + Interest + (Annual Tax / 12) + (Annual Hazard Ins / 12) + Monthly PMIWorked Example: $400,000 loan at 6.5% interest on $500,000 home ($5,000 tax/yr, $1,200 ins/yr)
Calculation: P&I = $2,528.27/mo. Taxes = $416.67/mo. Insurance = $100.00/mo. PMI = $0 (20% down).
Result: Total Monthly PITI = $3,044.94/month
Key Takeaway: Always budget for PITI rather than base principal and interest alone when evaluating home affordability.
