This worksheet from Laurelwick Lenders in Lake Havasu City, Arizona explains markup and gross margin, converts between them with worked tables, and shows how margin decides how much new payment a business can carry. It is arithmetic for your own numbers, not a calculator widget and not an offer; every figure in the examples is invented.
Markup vs Margin Calculator: What Plumbers, Electricians and Painters Compare
Plumbers, electricians and painters price jobs by marking up cost: materials plus labor, times a markup. A funding partner reads the result the other way, as gross margin on the profit and loss statement. The two percentages are never the same number, and confusing them is how a crew that thinks it earns 40% ends up with far less.
Illustration only, invented figures: a job costing $8,000 marked up 40% is priced at $11,200. The markup is 40% of cost, but the gross margin is 28.6% of price (our arithmetic).
| Markup on cost | Gross margin on price |
|---|---|
| 20% | 16.7% |
| 25% | 20.0% |
| 33.3% | 25.0% |
| 50% | 33.3% |
| 75% | 42.9% |
| 100% | 50.0% |
Gross Margin Calculator Percentage Around Lake Havasu City, AZ: Uses and Trade-Offs
Gross margin as a percentage is gross profit divided by sales. Around Lake Havasu City, AZ the uses are practical: setting a price, comparing jobs, and checking whether a new payment fits. The trade-off is that a single margin hides the mix; a shop selling parts at one margin and labor at another should calculate each.
| Target gross margin | Markup needed on cost |
|---|---|
| 20% | 25.0% |
| 30% | 42.9% |
| 40% | 66.7% |
| 50% | 100.0% |
Gross Margin Calculator Formula: How Mohave County, AZ Owners Use It
- Gross profit = sales minus cost of goods sold.
- Gross margin = gross profit divided by sales, times 100.
- Markup = gross profit divided by cost of goods sold, times 100.
- To price for a target margin: price = cost divided by (1 minus the margin).
Mohave County, AZ owners use the formula to size what the business can carry. Illustration only, invented figures: a shop with $21,000 a month of overhead at a 35% gross margin needs $60,000 a month in sales to cover it (our arithmetic). An invented new $1,450 monthly payment needs about $4,143 more in monthly sales at that margin.
How Self-Employed Owners and Small Crews Read the Result
Self-employed owners and small crews read the result in three steps. First, compare the margin on recent jobs with the margin on the profit and loss statement; a gap means costs are leaking between the quote and the books. Second, check the margin month by month; a partner reads the thinnest months. Third, test any new payment against gross profit, not sales.
- A margin that falls as sales rise can mean underpriced jobs.
- A margin that swings by month can mean uneven materials buying.
- A margin steady across jobs supports a funding request built on it.
Markup and Margin on a Kitchen Menu and a Parts Counter
Kitchens and repair shops price items, not jobs, so the arithmetic runs per plate or per part. Illustration only, invented figures: a plate with $4.20 of food cost sold at $14.00 carries a markup of 233% and a gross margin of 70% (our arithmetic). A filter bought for $9.00 and sold for $18.00 carries a 100% markup and a 50% margin in the same invented terms.
Labor changes the picture. A repair shop's labor sales carry no parts cost, so a shop's blended margin depends on the mix of labor and parts on each ticket. Calculate margin separately for labor and for parts, then together, before reading the profit and loss statement.
Four Mistakes That Skew Markup and Margin for Small Crews
- Quoting a markup and reporting it to a partner as a margin.
- Leaving out freight, disposal or permit costs from the cost side of a job.
- Leaving the owner's own labor out of cost, which inflates the margin.
- Reading one good month's margin as typical, instead of the twelve-month figure.
Each mistake makes the business look able to carry more payment than it can, and a partner reading the statements will find the gap.
Markup and Margin on Construction and Retail Statements in Mohave County, AZ
The county's two largest sectors by employer count price in both ways. Construction, with 672 employer establishments in 2023, quotes jobs on marked-up cost; retail trade, with 643, sets shelf prices from a target margin (County Business Patterns 2023). The construction page and the retail page show how partners read each.
Neither method is better. What matters is using one consistently and knowing what the other number is.
Taking the Margin Into a Funding Conversation
With the margin worked out, the payment question becomes concrete: how much more must the business sell to carry it? Bring that figure, the quote for what is being bought and the profit and loss statement to the first call. Working capital loans cover gaps, the guides page lists the license and food truck guides, and the online form starts a request.
