How the Estimate Template Works
This tool builds a tidy, itemized estimate (also called a quote) for a job and totals it for you. Enter who prepared it and who it is for, then add one line per task or material with a quantity and unit price. Add an optional contingency percentage for unexpected costs and a tax rate, and the estimated total updates instantly.
The Formula
For each line, the amount is quantity × unit price. The estimate totals are:
Subtotal = Σ (line amounts) Contingency = Subtotal × contingency% Tax = (Subtotal + Contingency) × tax% Estimated total = Subtotal + Contingency + Tax
Worked Example
A contractor quotes 8 hours of labor at $65/hr plus $480 of materials, with a 10% contingency and no tax:
- Labor: 8 × $65 = $520.00
- Materials: 1 × $480 = $480.00
- Subtotal = $520.00 + $480.00 = $1,000.00
- Contingency = $1,000.00 × 10% = $100.00
- Estimated total = $1,000.00 + $100.00 = $1,100.00
Estimate vs. Quote vs. Invoice
| Document | When it is used | Binding? |
|---|---|---|
| Estimate | Before work, costs uncertain | No |
| Quote | Before work, fixed scope | Yes |
| Invoice | After work, requesting payment | Yes |
Tips for an Accurate Estimate
- Break the job into line items so the client sees exactly what they are paying for.
- Add a contingency of 10 to 20 percent on jobs where surprises are likely.
- State that it is an estimate and note how long the pricing is valid.
When the estimate looks right, open the worked-example panel and use Print to PDF to save or send it to your client.
Frequently asked questions
What is a job estimate?+
A job estimate is a written, non-binding projection of how much a piece of work will cost, broken down into labor, materials and other line items. It helps a client decide whether to proceed and sets expectations before any contract or invoice. Final billed amounts can differ if the scope changes.
What is the difference between an estimate and a quote?+
An estimate is an approximate figure that may change as work progresses, while a quote (or quotation) is a fixed price the provider commits to for a defined scope. Use an estimate when costs are uncertain and a quote when you can lock the price in.
Why add a contingency to an estimate?+
A contingency is a percentage buffer added to cover unexpected costs such as price changes, extra materials or unforeseen work. On construction and renovation jobs a contingency of 10 to 20 percent is common, so the final cost is less likely to exceed the estimate.
How do I calculate the total on an estimate?+
Multiply quantity by unit price for each line and add them for the subtotal. Add a contingency percentage of the subtotal, then apply tax to the subtotal plus contingency. The sum of subtotal, contingency and tax is the estimated total. This tool does each step for you.
Is an estimate legally binding?+
Generally no. An estimate is an informed approximation, not a contract, so the final invoice can be higher or lower. To make a price binding you need a quote or a signed contract that states a fixed amount and the scope it covers.
