How to Price a Remodeling Job: A Contractor's Markup & Margin Guide

Why pricing is the skill that keeps you in business

You can be the best carpenter in your county and still go broke if your pricing math is wrong. Most remodelers who fail do not fail at the work — they fail at the numbers. They confuse markup with margin, forget to load overhead into their rates, or skip contingency and eat every surprise out of their own pocket.

Pricing a remodeling job comes down to four moves, in order:

- Total your direct costs (materials and labor for this job) - Account for overhead (your cost of being in business) - Add contingency for the unknowns - Apply markup to hit your target margin

Get that sequence right and consistent, and your bids stop being guesses. They become repeatable math you can defend to a client and trust at year-end. Skip a step, and you will win jobs you lose money on — the worst outcome in this trade, because you are busy and broke at the same time. The rest of this guide walks each move with the formulas you can apply tomorrow.

Markup vs margin: the difference that costs contractors money

This is the single most expensive misunderstanding in remodeling. Markup and margin are not the same number, and treating them as if they are will quietly drain your profit.

Markup is what you add to your cost. Margin is what you keep as a percentage of the final price.

Here is the relationship:

- 1.25x markup = 20 percent margin - 1.43x markup = 30 percent margin - 1.50x markup = 33 percent margin - 1.67x markup = 40 percent margin - 2.0x markup = 50 percent margin

Notice that a 50 percent markup is only a 33 percent margin, not 50 percent. Contractors who think they added 50 percent so they are making 50 percent are leaving real money on the table on every single job.

The formulas: Price = Cost x Markup. Margin = (Price minus Cost) divided by Price. To hit a target margin, use Price = Cost divided by (1 minus margin). Want a 35 percent margin on a 20,000 dollar job? 20,000 divided by 0.65 = 30,769 dollars. Memorize the conversion table above and you will never quote blind again.

Don't forget overhead

Direct costs are only part of the picture. Overhead is everything it costs to run your business whether or not you have a job today — and if you do not bake it into pricing, your profit is really just unpaid overhead.

Overhead typically includes:

- Vehicles, fuel, and maintenance - Insurance and licensing - Office, software, and phone - Marketing and lead generation - Your own salary as the owner-operator - Admin, bookkeeping, and accounting

To find your overhead rate, total your annual overhead and divide by your annual direct-cost volume. If you spend 80,000 dollars a year on overhead and run 400,000 dollars in direct costs, your overhead rate is 20 percent. That means every job needs to carry an extra 20 percent just to keep the lights on, before you have made a dime of profit.

A common mistake is rolling overhead and profit into one fuzzy markup. Separate them: cover overhead first, then add profit on top. When you know your real overhead rate, you can spot the jobs that look profitable but actually lose money once your true cost of doing business is counted.

Build in contingency before you bid

Remodeling is the riskiest kind of construction because you are working on top of someone else existing structure — and existing structures lie. The wall is not square, the subfloor is soft, the previous owner wiring is a fire hazard. Contingency is how you price for the surprises you cannot see during the walkthrough.

Add 15 to 25 percent on top of your direct costs as contingency:

- New construction or simple cosmetic work: 10 to 15 percent - Standard remodels: 15 to 20 percent - Gut renovations and older homes: 20 to 25 percent

The homeowner conversation matters here. Frame contingency as a normal, professional line — an allowance for conditions you cannot fully assess until walls are open — not as padding. Clients who have remodeled before expect it; the ones who have not will thank you when you do not hit them with a panicked change order in week two.

If the surprises do not materialize, you finish under budget and look like a hero. If they do, you have already priced for them. Either way, contingency keeps a single rotted joist from turning a profitable job into a loss.

How to avoid underbidding

Underbidding is rarely one big mistake — it is a dozen small omissions that add up. Here are the leaks that quietly turn a winning bid into a losing job:

- Forgetting overhead, so your profit just covers your truck payment - Confusing markup with margin and pricing too thin - Skipping contingency and absorbing every surprise yourself - Underestimating labor hours, the most commonly missed line - Missing small materials: fasteners, adhesives, trim, transitions - Forgetting soft costs: permits, dumpsters, protection, cleanup - Quoting from memory instead of measuring

The biggest single cause of underbidding is bad measurements. If your square footage is off by 10 percent, your materials and labor are off too — and you do not find out until you are buying the second pallet of tile.

This is where scanning changes the game. An accurate digital measurement of the room, captured in minutes, feeds a complete material takeoff so nothing gets eyeballed. See our scan-to-estimate workflow for how contractors are closing this gap and bidding from real numbers instead of rounded guesses.

Putting the formula together

Here is the full pricing sequence in one place. Run it the same way every time and your bids become consistent, defensible, and profitable.

Step 1, direct costs: add up materials and labor for the job.

Step 2, add contingency: direct costs x (1 + contingency rate). On a 20,000 dollar job at 20 percent, that is 24,000 dollars.

Step 3, apply markup for overhead and profit: to hit a 35 percent margin, divide by (1 minus 0.35): 24,000 divided by 0.65 = 36,923 dollars. That is your client price.

Step 4, sanity check against the ranges: does cabinet cost land near 29 to 40 percent of the total? Is labor in the 20 to 30 percent band? If a component is wildly off, find the error before you send it.

The catch is that running this by hand for every bid is slow, and slow estimates lose jobs to faster competitors. Alcovia compresses the whole sequence: scan the room, and the Growth plan generates a material takeoff and an instant estimate from your own price list. You stay in control of your markup — the app just does the tedious math. See how it works.
