How this calculator helps
Deal quality is relative. If you can estimate a fair typical price from price history, MSRP, or comparable listings, you can quantify how good today’s offer is.

How to estimate “normal”
Use your tracker’s historical median, competitor averages, or manufacturer list. The better the baseline, the more meaningful the savings percent.
