How Deal Analyzer Works
Discover how our advanced algorithm compares your mortgage rate against 50+ years of historical data to give you an accurate assessment of your deal quality.
The Science Behind Your Analysis
Our Deal Analyzer uses real Federal Reserve data to give you an objective assessment of your mortgage rate.
When you submit your mortgage details, our system doesn't just guess—it pulls actual historical interest rate data from the Federal Reserve Economic Data (FRED) database. This gives you a data-driven comparison that's based on real market conditions from your loan's start date.
The 4-Step Analysis Process
From your input to your personalized results in seconds
Step 1: Input Your Data
Enter your loan amount, interest rate, loan term (15 or 30 years), and when your loan started. We need this to compare against the right historical period.
Step 2: Fetch Historical Data
Our system queries the Federal Reserve database for the actual average mortgage rates during your loan's start month and year.
Step 3: Calculate the Difference
We compare your rate against the historical average and calculate exactly how much better or worse your deal is compared to the market.
Step 4: Get Your Rating
Based on the difference, you receive a "Great," "Fair," or "Poor" rating with specific recommendations for your situation.
