How to compute selling price from cost and markup

1. Enter the cost

   "Cost" is what the item costs you to acquire or produce — supplier price plus inbound freight, but not your overhead. Use the same currency you'll charge in.

2. Enter the markup %

   "Markup %" is the percent over cost you want to add (e.g. 50 turns $10 into $15). Markup ≠ margin: 50% markup is a 33.3% margin.

3. Press Run

   Result returns sellingPrice = cost × (1 + markup% / 100), rounded to 2 decimals. Sales tax and other downstream fees are NOT added — pair with sales-tax-calculator-online if you need the consumer price.

4. Inverse: from price + margin

   If you have a target margin instead of markup, use profit-margin-calculator-online (cost + price → margin). To go from price + margin → cost, solve `cost = price × (1 − margin%/100)` by hand.
