Build a clearer renovation budget by bringing materials, labour, permits and other expenses into one calculation. The tool adds a contingency percentage, shows the total and breaks the finished budget into cost shares.
It suits early planning for a kitchen, bathroom, bedroom, living room, full home or another project. Use it to compare a cautious budget with a leaner one before requesting detailed quotations or committing to the work.

Contingency share
Shares are shown as a percentage of the total budget. A contingency of 10–20% is sensible for most renovations — older properties and structural work usually need the higher end.
How to Use This Tool
- Select the room or project type.
- Enter your materials cost, labour cost and permits or other expenses.
- Set the contingency percentage you want to include.
- Select Calculate Total Budget.
- Review the subtotal, contingency amount, total budget and percentage share of each part.
This is a budgeting estimate, not a quotation. The calculator itself notes that 10–20% contingency is sensible for most renovations, with older properties and structural work usually needing the higher end. Update the figures whenever a supplier or contractor gives you a firmer price.
