Renovation Budget Planner
Enter the total budget you have available, allocate it across rooms and projects by priority, and see what remains after contingency. This tool plans your budget. It does not estimate renovation costs.

Quick Start
Tip: Mark anything you could postpone as Nice-to-have or Optional. If real quotes come in higher than planned, these are the easiest places to review first.
Project
Total Budget
Contingency is reserved from your total budget before any room or project spend is allocated, so it is never counted twice.
Rooms & Projects
Add each room or project you are planning for, set a priority, and enter the amount you plan to spend. Planned spend is a number you choose, not a calculated cost.
How the renovation budget planner works
A planner, not an estimator
This tool starts from the budget you already have, not from a calculated market price. Enter your total available budget, add each room or project, assign a priority and a planned spend, and the planner shows what is left after your contingency reserve. If you do not yet know what your renovation is likely to cost, the Home Renovation Cost Estimator and the single-room calculators on this site build that estimate from area, trade rates and scope. Bring those numbers back here once you have them.
How the numbers add up
Your contingency reserve is calculated first, as a percentage of your total budget, and set aside before anything else. What remains is the amount available for rooms and projects. Fixed costs and every room's planned spend are added together to get your allocated total. Subtract that from the available amount and you get what remains: a positive number means room to spare, zero means the budget is fully allocated, and a negative number means the plan currently asks for more than you have available.
Setting priorities
Must-have covers the work the project cannot go ahead without. Nice-to-have and Optional mark spend you would like but could postpone or drop if needed. When the plan goes over budget, the Flexible Allocations section lists Optional and Nice-to-have items together so you can see where there is room to adjust, without the tool making that call for you.
What this planner does not do
It does not price materials, labour or trades, and it does not know your local market rates. Every amount comes from you. For a cost estimate built from typical trade rates, scope and market level, use the Home Renovation Cost Estimator or the room-specific calculators on this site.
