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.

The short version

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.

Price needed = New cost ÷ (1 − target margin)

A guide, not financial advice. Figures are estimates based on a blended inflation figure you provide. Your own mix of costs may differ.

Standing still is a decision too

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.

If your costs rise 12% and your price does not move, you need roughly a 12% price rise just to stand still on margin. Anything less than that is a pay cut you gave yourself without deciding to.

Why the math works out this way

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.

Raising prices does not have to be dramatic

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.

Questions tradespeople ask

How often should I actually review my prices?
At least once a year, and sooner if you notice a specific cost, like materials or fuel, has moved a lot. A short annual check against your actual costs beats guessing whether "it feels about right" still holds.
How much can I raise prices without losing customers?
A rise that tracks genuine cost inflation is usually well tolerated, since customers understand that costs go up everywhere. Steep, sudden jumps after years of no movement are what tend to cause pushback, not a modest annual adjustment.
What if my competitors have not raised prices?
Someone is either absorbing the same cost rises you are, or quietly cutting corners to hold their price. Pricing to your own real costs and margin is a safer long-term position than matching a competitor whose numbers you cannot see.
Should new customers pay more than existing ones?
Many trades apply new pricing to new quotes straight away and phase it in for existing regular customers over their next job or two. Whatever you choose, be consistent and clear about it rather than deciding case by case.
What if I do not know my exact cost inflation?
A rough blended estimate across your main costs, materials, fuel, wages, is good enough to work with. The point is to stop treating your price as fixed forever, not to get the inflation figure to the decimal.
