If your costs have gone up and your prices have not, your margin is quietly shrinking without you doing anything wrong. See exactly how much ground you have lost, and what it takes to get it back.
If your costs have risen since you last put your prices up, your margin has shrunk even though you have not changed a thing. Work out your real margin today at your current price, and the price you would need to charge to get back to the margin you started with.
What has changed while your price stayed the same.
What you charge now, and the margin you started with.
A guide, not financial advice. Figures are estimates based on a blended inflation figure you provide. Your own mix of costs may differ.
Nobody decides to cut their own margin. It just happens, a little at a time, while materials, fuel and wages creep up and the price on the quote stays exactly where it was last year. Nothing about the job changed. The cost of doing it did.
Margin is profit as a share of your price. If your costs go up and your price does not, more of that price is eaten by cost, so the share left as profit shrinks. To get back to the same margin, your price has to grow by roughly the same percentage your costs did, because the relationship between cost and price is what margin actually measures.
A price rise that simply keeps pace with cost inflation is not you getting greedy, it is you standing still in real terms. Most customers barely notice a price move that reflects the same cost pressure everyone else is dealing with. The trades who struggle are usually the ones who let it slide for years and then need a much bigger jump all at once to catch up.
