Alteration Cost Estimator

This calculator has no numeric inputs at all -- every field is a dropdown -- so every result comes from combining fixed lookup tables rather than scaling a formula. Estimated Cost starts from a base price keyed jointly to Garment Type and Alteration Type (a six-by-four table, e.g. $12 to hem pants versus $45 to taper a jacket, lines 10-17), then multiplies that base by two separate factors: a Fabric Type multiplier (1.0x for cotton up to 2.0x for leather, lines 24-30) and a Complexity multiplier (1.0x simple up to 1.8x complex, lines 34-38) -- both applied together, not added (line 41), so choosing both a premium fabric and a complex job compounds rather than just stacking a flat surcharge.

Low Estimate and High Estimate are not a symmetric range around the mid-range Estimated Cost: Low is 85% of the combined base cost while High is 125% of it (lines 43-44), a 15-point-below / 25-point-above spread rather than an even plus-or-minus. Turnaround Time starts from a fixed number of business days set purely by Complexity -- 3, 5, or 8 days -- and then Fabric Type can add more on top of that: leather adds 3 extra days, silk adds 2, and the other three fabrics (cotton, denim, wool) add none (lines 49-55). Rush Fee is always 50% of the mid-range Estimated Cost specifically, never of Low or High Estimate (line 58), and Total with Rush is just Estimated Cost plus that Rush Fee, which works out to exactly 1.5 times Estimated Cost every time a rush is added (line 66).
