What this calculator does

Pricing a part means balancing profit against what a customer will actually pay. This calculator takes what you paid for a part and the markup percentage you want, and returns the price to charge and the exact dollar amount you are marking it up.

Selling price

$130.00

Markup amount

$30.00

The parts markup formula

Selling Price = Cost x (1 + Markup% / 100). Two numbers go in. Cost price is what you actually paid the supply house or distributor for the part, separate from the retail price printed on the box. Markup percentage is how much you want to add on top of that cost, expressed as a percent of the cost. Margin works off the final price instead, a different number, covered a bit further down.

Move the percentage into a decimal, add 1, multiply by cost. A $50 part at a 25 percent markup: 50 x 1.25 = $62.50. The $12.50 difference is the markup amount, the second number this calculator returns once you enter valid numbers above.

Parts markup covers more than profit

A part sitting on a shelf still costs money while it waits to be used. It ties up cash the business already spent, it takes up space on a truck or in a warehouse, and if it fails during the warranty window, your business eats the cost of the return trip and the replacement part on top of the technician’s time already spent. Markup is how those costs get paid before the sale ever happens, built into the price up front.

Four costs typically sit inside that percentage. The truck, the warehouse, and the person who orders and receives inventory rarely show up on a per-part invoice, so the markup is what covers a share of them. A part that fails in month two comes back on your dime: a diagnosis, a return trip, sometimes a full refund, and the markup collected on every part that holds up is what pays for the ones that don’t. Cash tied up in a shelf part earns nothing until it sells, and if the part goes obsolete before it moves, that money is gone for good. A part pulled off the truck at 9am also closes a job the same day a special order would have taken a week to finish, and the customer is paying for that speed as much as for the part itself.

Markup and margin measure the same profit differently

Markup and margin are both profit expressed as a percentage, they just divide by a different number. Markup divides profit by what the part cost you. Margin divides that same profit by what you charged for it. Take the $50 part marked up 25 percent to $62.50 from above: the $12.50 profit is a 25 percent markup on the $50 cost, but only a 20 percent margin on the $62.50 selling price, because margin’s denominator is the bigger number.

That gap widens as the percentage climbs, and it is where a lot of pricing plans go wrong. A shop that sets a 50 percent markup target on parts and assumes that is also a 50 percent margin is overstating its own profitability by a third; the actual margin on a 50 percent markup works out to 33 percent.

A worked example: pricing a stocked part

An HVAC tech carries a dual-run capacitor on the truck that cost the shop $19 from the supply house. At a 45 percent markup, Selling Price = $19 x (1 + 0.45) = $27.55. The markup amount, $8.55, covers the cost of stocking that part on the truck in the first place; profit on the sale itself is only part of what that dollar amount pays for.

Compare that to a $2,400 condenser the same shop orders in for an install. A 45 percent markup on that unit adds $1,080 to the price, likely pricing the homeowner out of the job or out of your bid entirely. Most shops solve this with a sliding scale in practice: a higher percentage on small, commonly stocked parts where the dollar amount stays reasonable, and a lower percentage on big-ticket equipment where the same percentage would add too much in raw dollars. That is a general industry practice, worth building a pricebook around instead of using one flat number across everything a business sells.

What changes the right number for a given part

The markup that makes sense on one part rarely makes sense on all of them. A part with a high return or failure rate needs a bigger cushion for warranty risk than one that almost never comes back. When every shop down the street stocks the same part, the number needs to come down, since a customer with a smartphone can price-check it before you have even left the driveway. A maintenance-agreement customer who calls every year is worth protecting with a fair price more than a one-time emergency call is.

None of that is something a calculator can decide on its own. It comes down to your supplier costs, your local market, and how much risk your business is carrying by keeping that part on the shelf. This tool gives you the math; the percentage is still your call.

Consistent pricing on every quoted job, not just parts

A markup percentage only holds up if every tech quotes the part the same way. A customer calls back about a part they bought last month, and the number a different tech gives them today does not match what they paid the first time. Holding that line means every call and every priced estimate draws from the same pricebook, no matter who answers the phone. AutoRev answers instead, prices the part from your own book, and quotes the same number no matter which line rings.

AutoRev is an AI coworker you direct, not one feature bolted onto your phone line. Hand it a task, quoting a part, pricing a full estimate, texting a customer their invoice, chasing a quote that went quiet, and it runs the task the way a trusted new hire would. It plugs into the FSM or CRM your shop already runs, so the pricebook and the job history stay in one place instead of living in a second app someone has to keep updated.

Markup questions

What comes up before pricing a part or building a pricebook.

Selling price equals cost multiplied by one plus the markup percentage as a decimal: Selling Price = Cost x (1 + Markup% / 100). Enter what you paid for the part and the percentage you want to add, and this tool returns both the price to charge and the exact dollar amount of the markup.

There is no single number that is correct for every trade or every part. In general industry practice, a lower markup, often in the 20 to 30 percent range, tends to apply to bigger-ticket items where the same percentage adds up fast in raw dollars, while a higher markup, sometimes 40 percent or more, applies to small stocked parts where the dollar amount stays reasonable even at a higher percentage. Treat any range you read as a starting point for building your own pricebook.

No, and mixing the two up is one of the most common pricing mistakes in the trades. Markup divides profit by cost. Margin divides that same profit by selling price, which is always the larger number, so margin is always a smaller percentage than markup on the same job. Run the same cost and selling price through the profit margin calculator to see the margin side of the math.

Because the labor rate and the part markup usually cover different costs. An hourly rate is built to cover payroll, drive time, and shop overhead tied to the technician. The part markup covers the cost of carrying that part before it ever gets installed: the cash tied up on a shelf, the truck space it takes, and the warranty exposure if it fails after the job. Pricing the part as a pass-through at cost leaves those costs uncovered.

Most shops do not run one flat number across the board. A small, commonly stocked part that carries real warranty risk usually justifies a higher percentage, since the resulting dollar amount stays reasonable to the customer. A large piece of equipment usually needs a lower percentage, since the same percentage on a bigger cost adds up fast and can price you out of a bid. A sliding scale by part category, built into a pricebook, is common industry practice.

Rerun the calculation with the new cost. Markup is a percentage of cost, so when cost moves, the selling price should move with it, unless you already quoted a fixed price to the customer before the increase. Some shops build a small buffer into standard markups on parts with volatile pricing specifically to absorb small supplier swings without repricing every job.

No. A pricebook assigns a specific price or markup rule to every part number a business stocks, built once and referenced on every job. This calculator is the fast version for a single part or a quick sanity check on a number, useful before that pricebook exists or when a one-off part needs a price on the spot.
