How to Use the Markup & Tax Calculator
This calculator is most powerful when used from the full estimator on the homepage — it automatically reads your subtotal from all added line items. On this standalone page, set your markup and tax percentages to see how they affect totals. Use the main estimator to combine all calculator outputs into one estimate before applying markup and tax.
How It Calculates
Tax Base = Subtotal + Markup Amount
Tax Amount = Tax Base × (Tax% / 100)
Grand Total = Tax Base + Tax Amount
Tax is applied to the marked-up total, not the original subtotal — this reflects standard invoicing practice where tax applies to the full selling price.
What to Know Before You Calculate
- Markup covers overhead + profit: A 15% markup should cover your overhead (office, equipment, insurance, bonds) and profit. If overhead is 8%, profit is the remaining 7%. Know your own overhead rate before setting markup.
- Tax rate by province: Ontario HST = 13%, Alberta (GST only) = 5%, BC = 5% GST + 7% PST on some items. Confirm the applicable rate for your jurisdiction and the type of work.
- Tax on residential new construction: New home construction may qualify for HST New Housing Rebate programs. This changes the net tax payable — consult a tax professional.
- Custom tax label: This calculator supports custom tax labels (HST, GST, PST, Sales Tax) so the estimate output matches your invoice.
Common Mistakes
- Confusing markup with margin. A 20% markup is not a 20% margin. Markup is on cost; margin is on selling price. Make sure your pricing model uses the correct basis.
- Applying tax to the subtotal instead of the marked-up total. Tax applies to the selling price (subtotal + markup), not the cost subtotal. This calculator handles this correctly.
- Using the same markup for materials and labour. Some contractors apply different markup rates to materials vs. labour. If so, calculate each component separately before combining.
- Forgetting subcontractor markup. If you are GC-ing and using subcontractors, you need to mark up their quotes too. Include sub quotes in the subtotal before applying your GC markup.
Frequently Asked Questions
What is a typical contractor markup for concrete work?
Contractor markups for concrete work typically range from 10–25% on top of direct costs (materials and labour). A 15% markup is common for residential work; 20–25% for commercial. Markup covers overhead, equipment, bonds, insurance, and profit.
Is HST charged on concrete construction in Canada?
Yes, in Ontario and other HST provinces, new residential construction and commercial construction services are subject to HST (13% in Ontario). New home construction may qualify for HST rebates under certain programs. Always confirm the applicable tax rate and rebate eligibility with your tax advisor.
What is the difference between markup and margin?
Markup is calculated on cost: a 20% markup on $100 = $120 selling price. Gross margin is calculated on selling price: $20 gross profit / $120 selling price = 16.7% margin. A 15% markup = ~13% margin. Contractors typically think in markup; accountants typically think in margin.
Is tax applied before or after markup on a concrete estimate?
In standard practice, markup is applied to the subtotal of direct costs first. Tax (HST/GST/PST) is then applied to the marked-up total, as tax applies to the full selling price. This calculator follows this convention: Subtotal → + Markup → Tax Base → + Tax = Grand Total.
