Measure remodel cost overruns in dollars and percentage terms while tracking approved changes, pending exposure, and contingency.
Use net approved changes
An overrun should account for both additions and credits. Summing only added costs exaggerates the true drift if the project also received reductions.
Percentage gives context
A $5,000 increase means something different on a $25,000 project than on a $150,000 project. Percentage drift gives that context.
Contingency is the early-warning system
Compare approved cost increases with the contingency you set at the start. When approved changes consume the full cushion, the project is moving beyond the buffer.
Worked example: dollar drift versus percentage drift
If a $65,000 remodel has $8,000 of net approved changes, the project is now $73,000 before any pending work. That is an $8,000 increase, or about 12.3%. The percentage matters because the same $8,000 increase would represent a much larger change on a $25,000 project.
Practical homeowner checklist
Questions worth asking your contractor
- Which approved changes were optional upgrades versus unexpected work?
- Are there any known costs not yet priced?
- How much work remains that could still generate change orders?
- Are pending decisions likely to exceed the remaining contingency?
Common mistakes to avoid
- Looking only at individual upgrades instead of the accumulated change total.
- Treating contingency as extra budget that should automatically be spent.
- Ignoring pending costs when deciding whether another upgrade is affordable.
Frequently asked questions
What should I track during a renovation?
Keep the original contract amount, approved additions, credits or refunds, pending changes, payments, and an optional contingency. Those pieces let you calculate a current approved project cost and a separate possible total.
Should pending changes count in my renovation total?
Keep pending work visible, but separate it from the approved project cost until you actually approve it. That distinction keeps committed cost from becoming inflated by options you may never accept.
How do I record a contractor credit or refund?
Record it as a negative project change. Once approved, it reduces net approved changes and lowers the projected final cost.
How often should I update my renovation tracker?
Update it whenever you approve or reject a change, receive a credit, make a payment, or learn that a previously uncertain cost has become more concrete.
