Count the work before choosing a price
Enter materials, hours × your labor rate, and overhead. Include preparation and finishing without double-counting outside services. The rate is your assumption, not a market wage.
An illustrative cost and margin example
Illustrative cost: $80 materials + 12 hours × $20 + $15 overhead = $335. With no fees, a 20% margin needs $335 ÷ 0.8 = $418.75, leaving $83.75 above entered costs.
A 20% markup instead gives $402; its $67 difference is 16.67% of price. These are examples, not industry rates.
Account for selling fees without hiding them
For cost C, fixed fee F, fee fraction R and target margin M: price = (C + F) ÷ (1 − R − M).
For markup U: price = [C × (1 + U) + F] ÷ (1 − R). Fixed fees are not marked up. Fees plus margin must be below 100%. Taxes and unentered costs remain outside the result.
Test the price against real demand
This is a cost-based target, not buyer-demand evidence. Dimensions only calculate price per square inch. Compare real offers and track time and receipts.
Use fabric, binding and batting for quantities; enter actual purchase costs.
