About this calculator
Bathroom Remodel is priced per square foot of bathroom, and the number that actually decides whether the job is profitable is the fully-loaded cost per sq ft — material plus waste, plus crew hours at your real burdened labour rate, plus the overhead every job has to carry. This calculator builds that number from the ground up rather than reverse-engineering it from a competitor's price. At the defaults here, material runs about $210.00 per sq ft and labour runs roughly 1.5 crew-hours per sq ft, which at a $68/hr burdened crew rate is about $102.00 per sq ft in labour alone. Bathrooms have the highest cost per square foot in the house because every trade works in the same 40 square feet. Full bathroom remodels typically run $200–$500 per square foot. Change the crew rate to your real burdened cost — wages plus payroll tax, workers' comp, vehicle, insurance and non-billable time — because using a bare wage rate is the single most common reason a busy bathroom remodel business still ends the year with no profit. The markup field is a markup on total cost, not a margin: a 35% markup on cost is a 25.9% gross margin, and confusing the two is worth thousands a year on a full schedule.

FAQ
How much should I charge per sq ft for bathroom remodel?
Work from cost, not from the market. Full bathroom remodels typically run $200–$500 per square foot. Take your material cost per sq ft, add your waste factor, add crew hours times your burdened hourly cost, add your overhead allocation, then apply your markup. If that number lands well above local pricing, the problem is usually productivity or overhead, not greed.
What is a burdened labour rate and why does it matter here?
Burdened rate is what an hour of crew time truly costs you: wages, payroll taxes, workers' compensation, vehicle and fuel, tools, insurance, and the unbillable hours between jobs. It is commonly 1.4x to 1.8x the bare wage. Quoting off bare wages is the fastest way to run a busy, unprofitable business.
Is markup the same as profit margin?
No, and the gap is bigger than people expect. Markup is added to cost; margin is a share of the price. A 35% markup gives a 25.9% margin, and a 50% markup gives a 33.3% margin. If you need a 40% margin you must mark up by 66.7%.
How should I handle the waste factor on bathroom remodel?
The default here is 8%, which is a reasonable starting point for straightforward work. Complex layouts, cuts, patterns and awkward access all push it higher. Track your actual waste for a few jobs and replace the default with your own number — it is one of the easiest measurable wins in estimating.
Should overhead be a percentage or a fixed amount per job?
Both work if you are consistent. Percentage-of-cost is simpler and self-scaling; a fixed per-day allocation is more accurate when your jobs vary wildly in size. What fails is having no overhead line at all and hoping the markup covers it.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
