Your Project

What Are You Planning?

Use measured dimensions when you have them. The calculator uses a reasonable room-size assumption if you do not.

Approximate Room Dimensions (optional)
Expected Work Choose the work you expect

Choose each element you would like included in the planning range. You can adjust these selections at any time.

Preparation and Walls

Fixtures, Tile and Plumbing

Floors and Finishing

Electrical and Comfort

Planning only — not a quote, construction contract, or guarantee of final price. Default rates are preliminary planning allowances. Confirm quantities, local supplier prices and trade quotes before committing to a budget.

Choose the Work That Matches Your Project

The project type filters the calculator’s work list. Select only the tasks you expect, then use the itemized result to ask contractors about inclusions, exclusions and existing conditions.

Bathroom Renovation

Build a bathroom scope from demolition, a toilet, vanity, faucet, bathtub or shower, waterproofing, tile, ventilation, flooring and lighting. Replacing finishes in place is different from moving plumbing or rebuilding damaged surfaces.

Kitchen Renovation

Choose cabinets, countertops, backsplash, sink, faucet, appliance hookups, floors and electrical or ventilation work as needed. The kitchen list does not include toilet or bathtub replacement.

Basement Renovation

Start with framing, insulation, drywall, flooring and lighting. Add bathroom fixtures and plumbing only when they are part of the basement plan; review moisture, headroom and approvals separately.

Fence Installation

Enter total fence length in linear feet, then select fence installation, removal, a pedestrian gate or staining. Confirm property boundaries, grade changes and local requirements before relying on a budget.

Free Ontario Renovation Calculator: What It Estimates

This free tool from Karks Contracting builds an itemized planning range in Canadian dollars for kitchens, bathrooms, basements and individual renovation tasks. Choose your project type and city, enter room dimensions or fence length, and select matching work grouped by category. Built-in material and labour allowances produce the estimate without per-item price or quantity entry. No account is required.

How the Estimate Is Calculated

The calculator applies built-in quantity assumptions to the selected work and project dimensions. Labour uses the work quantity, finish level and a regional wage-based adjustment. The estimate adds 13% HST to materials and labour. Delivery, disposal, permits and a separate waste allowance are excluded; confirm the complete scope in a written quote.

Default rates are provisional allowances, not verified local averages. Supplier catalogues are not live price feeds. The calculator displays dated product-price snapshots for Home Depot, RONA, Home Hardware and IKEA as references; they are not complete installed-work prices and do not set assembly totals. City selection applies a regional labour proxy based on Job Bank carpenter median wages: Hamilton–Niagara $30/hour and Toronto region $36/hour (2023–2024 reference data, updated November 2025). The resulting 1.00× or 1.20× labour adjustment is a planning assumption across trades, not a city-specific contractor rate.

Renovation Calculator Questions

How accurate is an online renovation calculator?

Accuracy depends on the measurements and scope. This calculator estimates quantities, materials and labour using built-in planning allowances. Compare the assumptions with real contractor quotes. It cannot inspect concealed damage, determine structural requirements or replace an on-site assessment.

Can I estimate a kitchen, bathroom or basement renovation?

Yes, and fencing is also available. Work choices are grouped and change with the project type. The calculator applies quantities from room dimensions, fence length or stated defaults; fixtures default to one. If both floor finishes are selected, unmeasured quantities split the floor area equally. The optional AI builder suggests work items for review and leaves quantities to the calculator.

How does the selected city affect labour costs?

Hamilton, Burlington, Brantford, Stoney Creek and Waterdown use the Hamilton–Niagara baseline. Oakville, Milton, Mississauga, Brampton and Toronto use the Toronto regional proxy, 1.20× the baseline labour allowance. Materials are unchanged. Regional employee wages are not contractor billing rates; the adjustment is an approximation and must be checked against project quotes.

Are Home Depot, RONA and Tamarack prices live?

No. Supplier links help you research materials. Stored product prices are labelled snapshots, not live feeds or guaranteed offers. Confirm store availability, package coverage, delivery charges and the current price.

Does the AI option calculate my final quote?

No. The integrated AI builder maps your description to available work items. Review suggestions before adding them to your estimate. The calculator applies built-in quantities and prices; AI does not set either. Manual selection remains available without AI.
