Sales calculators
12 calculators
Sales calculators cover checkout and pricing math: tip amount and bill total, percent discount and sale price, unit price × quantity with tax, markup and selling price, gross margin, commission, break-even units, bundles, and layaway installments.
Each tool applies the percent or ratio to the labeled base (bill, list price, cost, or revenue). Register rounding and local tax rules can differ from the on-page result — use the figure as a check, not a receipt. Every sales calculator opens free with no account required.
