Retail promotional discounts and percentage markdowns are the primary marketing tools used by stores during clearance sales, Black Friday events, and seasonal liquidations.
The fundamental retail pricing formulas computed by this tool are:
\(\text{Savings Amount (\$)} = \text{Original Price} \times \left(\frac{\text{Discount \%}}{100}\right)\)
\(\text{Discounted Sale Price} = \text{Original Price} - \text{Savings Amount}\)
\(\text{Sales Tax Amount} = \text{Discounted Sale Price} \times \left(\frac{\text{Tax Rate \%}}{100}\right)\)
\(\text{Final Out-of-Pocket Cost} = \text{Discounted Sale Price} + \text{Sales Tax Amount}\)
Sales tax is applied to the discounted sale price rather than the original sticker price. Enabling the Sales Tax Toggle allows you to calculate the exact cash amount due at the register.
