PROFIT MARGIN CALCULATOR
PROFIT MARGIN UK Seller Calculator
Work out your gross and net profit margins, and see the markup that actually delivers them, with a free calculator and Excel workbook.
Profit Margin Calculator
Margin is the share of each pound of sales you keep, and it comes in layers: gross margin survives the cost of the goods, net margin survives everything. The two tell you different things, so this calculator shows both.

Margin is profit over revenue; markup is profit over cost. They are different numbers, and pricing with the wrong one is the quietest way to undercharge: a 40% margin needs a 66.7% markup.

The workbook version itemises your overheads, converts margin to markup in both directions with an equivalents table, and prices a unit from the margin you actually want to earn.

Fresh takes on business and accounting.
Company law allows accounts to run for 18 months; corporation tax never allows an accounting period longer than 12. Here is how the split is drawn.
The associated companies rules get more involved once a group has layers. Sub-subsidiaries, dormant holding companies and short accounting periods, worked through in a single example.
An acquisition partway through the year still counts as an associated company for the whole accounting period. What that does to your thresholds, and to your tax bill.
