An estimate is a rough, non-binding approximation of cost — distinct from a quotation, which is a fixed, binding price offer computed from quantity times unit price. This generator builds an estimate from approximate line-item costs, with an optional variance percentage disclosed as a low/high range rather than a single fixed total.
Labeling a document as an estimate rather than a quotation sets the right expectation with a customer: actual costs may vary once the full scope is known.
How it works
Enter your business details and your customer's details, then add one line item per estimated cost. Optionally set a variance percentage (e.g. 15% for a ±15% range) to show a low/high estimate instead of a single total. The generator builds the estimate and lets you download it as a PDF.
- Enter your business details and your customer's details.
- Add one line item per estimated cost.
- Optionally set a variance percentage, then generate the estimate.
Examples
A project estimate with a variance range
A contractor estimates $7,000 in costs with a 15% variance, showing the customer a range of $5,950–$8,050 rather than a single fixed number.
A simple estimate without variance
A freelancer provides a rough estimate as a single total, without a variance range, for a smaller, well-understood project.
Who should use it
- Providing a rough cost approximation before finalizing project scope.
- Setting realistic cost expectations with a customer early in a project.
Industry applications
- Construction and contracting
- Freelance and consulting services
Advantages
- Clearly distinguishes non-binding estimates from binding quotations.
- Optional variance range for realistic cost expectations.
- No account, subscription or watermark.
Limitations
- Not a substitute for a formal quotation once scope and pricing are finalized.
Common mistakes to avoid
- Treating an estimate as a binding price commitment.
- Omitting a variance range when costs are genuinely uncertain.
Best practices
- Use a variance percentage when there's genuine uncertainty in the final cost.
- Clearly communicate to the customer that this is an estimate, not a fixed quotation.
Tips
- Follow up with a formal quotation once the scope is fully defined.
- Use a variance percentage that honestly reflects your confidence in the numbers.
