Markup and Margin Calculator (Gambia)

Questions people ask

What is the difference between markup and margin?

Markup measures profit against your cost; margin measures it against the price you charge. A 50% markup on a cost of 100 gives a price of 150, which is a 33% margin. Both describe the same sale, so quote whichever your trade uses, but never assume they are the same number.

What markup should I use?

There is no correct figure, only the one that covers your costs and the work you do not bill for. Trades quoting materials plus labour commonly work at 20% to 50% on materials, while retail often needs 100% or more to cover premises and stock that does not sell. Start from what you must earn a month, not from what a competitor charges.

Does the tax go on before or after the markup?

After. You mark up your cost to reach a selling price, and the consumption tax is then charged on that selling price. Adding the tax before the markup marks up the tax itself, which overcharges your customer and is not what the invoice should show.

Is my cost the price before or after tax?

If you can reclaim the tax on what you bought, use the cost before tax, because the tax is not really yours to bear. If you cannot reclaim it, the tax is part of what the item cost you and belongs in the figure you mark up.

Can I work backwards from the price I want to charge?

Yes. Choose Selling price, enter your cost and the figure you intend to quote, and the calculator shows the profit and both percentages. That is the quickest way to check whether a price a customer has pushed you to still leaves anything.
