What margin should a painting business make?

Gross margins in residential painting commonly sit somewhere between 30 and 50 percent before overheads, but the honest answer is that it depends on your overheads, your market and how much of the work you do yourself. The number that matters is whether it covers your fixed costs across a year, not whether it matches somebody else.

Is markup ever the right way to price?

Yes, and plenty of good businesses use it. It is simpler to apply on the spot. Just know what margin it actually produces, so the figure in your head matches the figure in your bank.

Margin vs markup, and the money it costs

The most expensive arithmetic mistake in the trade, and it is invisible on any single job.

The two are not the same thing

Markup is measured against what the job costs you. Margin is measured against what the customer pays. They are the same number only when both are zero.

Add forty percent to a cost of $6,000 and you get $8,400. Of that, $2,400 is yours — which is 28.6% of $8,400, not forty. To actually make forty percent you divide by 0.6, which gives $10,000.

Price = cost ÷ (1 − margin). Not cost × (1 + margin).

What it costs on a real job

The gap widens as the percentage rises, which is why it hurts most for the painters aiming highest.

You wanted	So you added	You actually made	On $6,000 of cost, you left behind
20%	20%	16.7%	$300
30%	30%	23.1%	$771
40%	40%	28.6%	$1,600
50%	50%	33.3%	$3,000

The last column is the difference between the price you charged and the price that would have hit the margin you thought you were running.

Why nobody notices

Because no single job announces it. Every quote looks reasonable, every job comes in about where you expected, and the shortfall only shows up at the end of a year that felt busy and finished thinner than it should have.

It is also self-reinforcing: a painter running at twenty-nine percent while believing they are at forty will win slightly more work than their competitors, which feels like the pricing is right.

What to do about it

Decide which one you mean, and then be consistent. Neither is wrong — a lot of trades genuinely price on markup and there is nothing dishonest about it. The damage comes from meaning one and calculating the other.

If you price on margin, divide. If you price on markup, multiply, and know that your real margin is lower than the number you are adding.
