The Quantitative Decision Matrix

Our Prequalification engine utilizes **Reverse Amortization** and **DTI (Debt-to-Income)** limits to estimate your purchasing power with banking-grade precision.

๐Ÿ“Š

Reverse Amortization
Logic

Standard calculators tell you your payment. We solve for the principal by calculating the present value (PV) of your maximum allowed monthly payment over the target tenure at market rates.

โš–๏ธ

DTI Efficiency
Modeling

Lenders primarily look at your **Back-End DTI**. By subtracting existing debt obligations from your gross capacity, we define the "mortgage ceiling" that preserves your financial stability.

๐Ÿ›ก๏ธ

Credit Tier
Risk Benchmarks

Interest rates are tied to creditworthiness. Our engine models the spread between "Prime" and "Sub-prime" credit scores to visualize how your FICO score impacts your maximum loan principal.

Frequently Asked Questions

How do I compare two loan offers?

Use our Compare mode! Enter both loan amounts, interest rates, terms, and closing costs. The calculator shows monthly payments, total interest paid, and total cost. Lower monthly payment doesn't always mean better - check total interest paid over the life of the loan. Our calculator makes it easy to see which loan saves you more money.

Should I refinance my loan?

Refinancing makes sense if: 1) New rate is at least 0.5-1% lower, 2) You plan to stay in the home/keep the loan long enough to break even (closing costs รท monthly savings), 3) You can reduce your loan term. Use our Refinance mode to calculate break-even point and total savings. If you'll move before break-even, refinancing may not be worth it.

What is a loan break-even point?

Break-even point is when your refinancing savings equal the closing costs. Formula: Closing costs รท Monthly savings = Months to break even. For example, if closing costs are $4,500 and you save $150/month, break-even is 30 months. If you plan to stay longer than 30 months, refinancing saves money.

How much can I borrow? (Loan prequalification)

Use our Prequal mode! Enter your monthly income, existing debt payments, credit score, and target debt-to-income (DTI) ratio. The calculator shows your maximum monthly payment and estimated loan amount. Lenders typically allow DTI up to 36-43%, but lower is better for approval and rates.

What is debt-to-income (DTI) ratio?

DTI is your total monthly debt payments divided by gross monthly income, expressed as a percentage. For example, if you earn $8,000/month and have $2,000 in debt payments, your DTI is 25%. Lenders prefer DTI under 36% for mortgages, but may approve up to 43%. Lower DTI = better rates and easier approval.

How does credit score affect loan rates?

Credit score significantly impacts loan rates. Excellent credit (760+) gets the best rates (~6.4%), good credit (700-759) gets slightly higher rates (~6.8%), fair credit (640-699) gets higher rates (~7.5%), and poor credit (<640) gets the highest rates (~8.5%+). Our calculator shows estimated rates based on your credit score.

What's the difference between interest rate and APR?

Interest rate is the cost of borrowing money. APR (Annual Percentage Rate) includes interest rate plus fees and closing costs, giving you the true cost of the loan. Always compare APRs when shopping for loans, not just interest rates. A loan with a lower rate but higher fees may have a higher APR.

Should I choose a 15-year or 30-year loan?

15-year loans have higher monthly payments but much less total interest. 30-year loans have lower payments but more total interest. Use our calculator to compare: If you can afford the 15-year payment, you'll save tens of thousands in interest. If cash flow is tight, 30-year gives flexibility, and you can always pay extra to shorten the term.
