Kitchen Remodel Estimating Guide for Contractors
A mid-range kitchen remodel costs $25,000–$55,000 and should be estimated by breaking the project into categories: cabinets (30–35% of budget), countertops (10–15%), appliances (15–20%), labor (20–25%), and flooring, plumbing, and electrical (10–15%). Mark up subcontractor costs 15–25% and target an overall gross margin of 35–45%.
Kitchen remodels are the highest-revenue projects most remodeling contractors handle. They are also the most complex to estimate — involving cabinetry, countertops, plumbing, electrical, flooring, appliances, tile, and finish carpentry. An inaccurate estimate can easily cost you $5,000–$10,000 in margin. This guide breaks down kitchen remodel estimating into a repeatable system that protects your profitability.
Breaking Down the Budget by Category
Every kitchen remodel estimate should be organized into clear categories. Cabinets: 30–35% of total budget. Stock cabinets run $5,000–$10,000 for a standard kitchen, semi-custom $10,000–$20,000, and full custom $20,000–$50,000+. Countertops: 10–15% of budget. Laminate costs $15–$30 per sq ft installed, quartz $50–$100, and natural stone $60–$150. Labor (your crews and subs): 20–25% of the total project. Appliances: 15–20% — always clarify who purchases appliances (you or the homeowner) in your estimate. Flooring: 5–8%. Plumbing and electrical: 5–10%. Backsplash and tile: 3–5%. Having consistent category percentages lets you quickly sanity-check your estimate — if cabinets are coming in at 50% of the total, either the cabinet selection is too expensive or the rest of your estimate is too low.
Site Assessment and Scope Definition
A thorough site assessment prevents expensive surprises. Measure the entire kitchen — not just cabinets, but walls, windows, doors, ceiling height, and the locations of plumbing, electrical, and HVAC. Open the cabinet under the sink and look for water damage. Check the floor for levelness. Note the age of electrical wiring and whether the kitchen has dedicated circuits. Ask the client specific scope questions: are walls being moved? Is the plumbing layout changing? Are you replacing or refacing cabinets? What appliance upgrades are planned? Will the project require permits? Document everything in writing and have the client sign off on the scope before you price — scope changes after estimating are the leading cause of kitchen remodel disputes.
Subcontractor Pricing and Coordination
Most remodelers subcontract plumbing, electrical, and sometimes countertop installation and tile work. Get written quotes from your subs before finalizing your estimate — never guess at sub costs. Mark up subcontractor prices 15–25% to cover your coordination time, scheduling, quality control, and liability. This markup is standard in the industry and covers real costs: you are managing the schedule, handling the client relationship, dealing with punch list items, and carrying the liability insurance. For a kitchen remodel with $8,000 in sub costs, your markup adds $1,200–$2,000 in revenue. Schedule subs in the right sequence: demo → rough plumbing and electrical → inspections → drywall and paint → cabinets → countertop template → countertop install → tile backsplash → final plumbing and electrical trim → flooring → final punch list.
Using Allowances for Client Selections
Allowances are placeholder amounts for items the client has not yet selected — commonly used for countertops, backsplash tile, faucets, lighting fixtures, and hardware. Set allowances based on the project tier. For a $35,000 mid-range kitchen: countertop allowance of $3,500 (covers quartz in most markets), backsplash tile allowance of $1,200, plumbing fixture allowance of $800, lighting fixture allowance of $600, and cabinet hardware allowance of $400. Clearly state in your estimate that allowances are estimates and the final price will adjust based on actual selections. When clients exceed allowances, send a change order before purchasing — never absorb the difference. Track allowance versus actual spending throughout the project to maintain your margin.
Contingency, Overhead, and Profit
Kitchen remodels in existing homes almost always uncover surprises behind walls, under floors, or inside cabinets. Build a contingency line of 5–10% into your estimate for unforeseen conditions. On homes built before 1985, increase this to 10–15% for potential asbestos, lead paint, or outdated wiring and plumbing. Your overhead (office, insurance, vehicle, marketing, software, continuing education) typically runs 15–25% of revenue for remodeling contractors. Add your profit margin on top — most successful remodelers target 8–12% net profit after all expenses. Combined, this means your total markup over direct costs should be 35–45%. A $30,000 direct cost kitchen remodel should be bid at $41,000–$55,000 to maintain healthy margins.
