The biggest mistake behind most searches for how to price remodeling jobs is confusing markup with margin. A remodeler who needs 28% of every dollar to cover overhead and profit, and who adds 28% to cost, comes up short on every job. Get that right, then handle allowances and change orders with the same discipline.
Quick answer: Estimate direct costs by trade and phase (demo, subs, materials, your crew's labor, dumpster and permits). Decide the gross margin you need from your overhead and profit targets, and price as cost divided by one minus that margin, not cost plus the same percentage. Use allowances for finishes the client has not chosen, a contingency or clear exclusions for hidden conditions, and price every change order with the same margin.

| If you need this margin | Divide cost by | Equivalent markup on cost |
|---|---|---|
| 20% | 0.80 | 25% |
| 25% | 0.75 | 33% |
| 28% | 0.72 | 38.9% |
| 33.3% | 0.667 | 50% |
Take last year's overhead (office, vehicles, insurance, estimating and project-management salaries, marketing, your salary as manager) as a share of revenue, then add the net profit you want. If overhead ran 18% of revenue and you want 10% net, you need a 28% gross margin on every job.
| Direct cost line | Amount |
|---|---|
| Demolition and haul-away (crew) | $1,800 |
| Cabinets | $14,000 |
| Countertops (templated and installed) | $5,200 |
| Plumbing subcontractor | $3,400 |
| Electrical subcontractor | $3,900 |
| Drywall repair and paint | $2,600 |
| Flooring | $3,300 |
| Carpentry labor (your crew, burdened) | $4,800 |
| Dumpster and permits | $1,400 |
| Total direct cost | $40,400 |
Illustrative costs only.
| Method | Calculation | Price | What you actually keep for overhead and profit |
|---|---|---|---|
| Markup of 28% | $40,400 × 1.28 | $51,712 | $11,312 = 21.9% of price |
| Margin of 28% | $40,400 ÷ 0.72 | $56,111 | $15,711 = 28% of price |
The difference on one kitchen is $4,399. Across a year of jobs, that is often the gap between a remodeler who grows and one who wonders where the money went.
When the client has not picked tile, fixtures or hardware, include an allowance: a stated dollar amount for that item at your cost basis, with the rule that the final price adjusts up or down to their actual choice. Make allowances realistic. Low allowances win the bid and then sour the relationship when every selection comes in over.
Old houses hide rot, outdated wiring and out-of-level floors. Either carry a contingency line, or list clear exclusions with unit prices ("subfloor replacement, if required, at $X per sheet installed"). Both are honest; silence is not.
Price every change order with the same margin as the original job, include the schedule impact, and get it signed before the work happens. Change orders written on a napkin and billed at cost are where many remodelers give back their profit.
Tie payments to milestones (deposit, rough-in, cabinets set, substantial completion) so you are never financing the client's project. Check your state's rules on deposit limits for home improvement contracts.
Detailed remodel estimates can take many hours: site visits, measurements, sub walkthroughs and selections. Many remodelers charge a design or preconstruction fee for larger projects and credit it to the contract if the client proceeds. It filters out clients who are only collecting numbers and pays for the time when a project does not go ahead. If you do not charge one, at least track estimating hours by project type so you know where your time goes.
Subcontractor bids are easy to drop into an estimate; your own crew's labor is where remodelers usually guess. Keep a simple record of actual hours by task on finished jobs: demolition per room, framing per wall, trim per room, tile per square foot. After a few jobs, those records make your labor estimates far more reliable than a rule of thumb, and they show which tasks your crew does profitably and which you should sub out.
Remodelers lose bids to slow estimates and lose margin to unwritten change orders. Unmanually is a 24/7 AI Office Manager you talk to from the site: "Add a change order for the Smiths, recessed lights over the island, four cans, schedule plus one day," and it writes it up at your margin, sends it for signature and follows up. It asks before anything that spends money.

Work back from the margin you need. If overhead is 18% of revenue and you want 10% net profit, you need a 28% gross margin, which is a markup of about 38.9% on cost, not 28%.
An allowance is a stated budget for a finish the client has not chosen yet; the contract price adjusts up or down to the actual selection.

Home service businesses answer only about half their calls (Invoca, July 2026), and owners spend about 11 to 16 hours/week on admin. Knowing what to do is the easy part; the money leaks out in the calls you can't take, the quotes nobody chases and the invoices that sit unpaid. Unmanually is a 24/7 AI Office Manager for remodelers that you run by voice from your phone:
Sources: Invoca, July 2026 (52% of home-service calls answered by a person, 60M+ calls); admin hours: Time etc / Censuswide 2023 and Amex SME Barometer 2026.
