Adjusted Total = (Original × (1 + Surcharge %)) - Discount

Applies a percentage increase for surcharges and then subtracts any flat dollar discounts or rebates.

A $10,000 order with a 5% fuel surcharge and a $200 bulk discount results in a $10,300 final total.

In volatile markets, the "sticker price" of an order is rarely the final price paid.

Shipping surcharges are often calculated as a percentage of the total order value.
Volume discounts can be flat-rate OR percentage-based; use $ for flat rebates.
Always verify if surcharges include tax or if tax is added at the end.

Double check these adjustments before processing your payment.

Whenever a supplier adds a "temporary" surcharge or applies a rebate after the initial quote is issued.

This tool applies the percentage surcharge to the base total first, then subtracts the flat discount.
