Questions people actually ask
- Does raising term change the answer in proportion?
- No, and that is the point of putting them side by side. Term changes by 40% while monthly payment changes by 23% in the opposite direction. The step table below shows which line breaks the proportion.
- What is held constant between the two columns?
- Everything except term: amount borrowed, annual interest rate (apr), interest compounds, you pay. That is what makes the difference attributable — change two things at once and neither column tells you which one moved the answer.
- Can I compare my own two numbers?
- Yes, from the address bar: add ?a.months=… and &b.months=… to set each side, and a parameter without a prefix sets both at once. The page is computed per request, so any pair works — these two are only the ones worth a link.
Change either side by adding query parameters — ?a.months=… and b.months=…. A parameter without a prefix sets both sides at once. Source: CFPB — auto loans and instalment credit, Federal Reserve G.19 consumer credit release
