Use the Repair Budget Planner to turn comparable contractor quotes into a low-to-high planning range with contingency. The tool shows its assumptions so you can change them rather than relying on a hidden market average.
Planned budget range—Adds your contingency to both ends of the quote range.
Formula used
planned low = low quote × (1 + contingency); planned high = high quote × (1 + contingency)
How to use the result
- Enter measurements or rates you can verify.
- Check the result for obvious unit mistakes.
- Save the assumptions with your project notes.
- Replace estimates with product data or real quotations as they become available.
Important limitations
- Quotes must describe broadly comparable scope
- Contingency does not replace inspection
- Allowances and provisional sums can still change
Before you buy or sign
- Verify measurements on site
- Use product-specific coverage or waste guidance where available
- Confirm taxes, delivery, permits, labour and disposal separately when relevant
- For safety-critical or structural work, use an appropriately qualified professional
Why RepairCostPilot shows the assumptions
A calculator is useful only when you can see what drives the result. These tools deliberately use simple inputs and avoid pretending that one national figure is an exact local contractor price.
