What this calculator works out

Useful for freelancers, trades and service businesses offering an agreed percentage reduction.

Calculation: Discount = original price × discount rate. Tax is then applied to the reduced price.

Practical example

A 12.5% discount on 640 removes 80, leaving 560 before any tax.

Use the result carefully

  • State whether a discount applies before or after tax.
  • Use a clear line description so the customer can see why the price changed.
  • Check that the discount does not remove the margin needed to deliver the work.
