Free Estimate & Quotation Generator
An estimate gives a potential client an approximate cost for a job before work begins, helping them decide whether to move forward without locking you into a fixed price. This tool builds a professional, itemized estimate you can send in minutes — add labor and material costs, adjust quantities, and download a clean PDF, all without creating an account or storing any data on a server.
How to create an estimate
- Add your business details and the client's name and contact info.
- List each task, material, or service with an approximate quantity and price.
- Apply tax or a discount if relevant.
- Add a validity date so the client knows how long the pricing holds.
- Download as PDF or print, then send it for approval.
How to write an estimate that wins the job
An estimate is an approximate price you give a client before work begins, so it should be clear enough to build trust but flexible enough that the final cost can shift if the scope changes. The most persuasive estimates break the total into line items, so the client sees exactly what they are paying for, and spell out what is — and is not — included in the price.
- Break costs down by line item instead of quoting one lump sum, so the client can see the value.
- Add a valid-until date (14 to 30 days is common) so pricing is not open-ended.
- State clearly that the figure is an estimate and the final price may vary with scope.
- Define what is included and excluded to prevent misunderstandings once work starts.
- Follow up a few days after sending — many jobs are won simply by checking in.
Frequently asked questions
What is the difference between an estimate and a quote?
An estimate is an approximate cost that can change as the scope of work becomes clearer. A quote is a fixed price the business commits to honoring once accepted. Estimates are used early in a project; quotes are used once the scope is confirmed. Read our full comparison.
Is this estimate generator free to use?
Yes, it is completely free, works in your browser with no signup, and your data is never uploaded or stored.
Can I turn an estimate into an invoice later?
Yes. Once the client approves the estimate and the work is complete, use the same line items in our invoice generator to bill them.
Should I add an expiration date to my estimate?
Yes, it's good practice. Material and labor costs can change, so including a validity period (for example, 30 days) protects you if the client delays accepting.
Is an estimate legally binding?
Generally no — an estimate is an approximate figure and is not binding. A formal quote is firmer and is more likely to be treated as a fixed price.
What should I include in an estimate?
A strong estimate lists your business details, an itemised breakdown of costs, the total, a validity date, and a clear note on what is and isn't included in the scope.
Why break an estimate down into line items?
Itemising costs shows the client exactly what they are paying for and makes it easy to adjust specific items if the scope changes — a single lump sum is much harder to justify.
How is an estimate different from a proposal?
An estimate focuses on price, while a proposal is a broader document that also explains your approach, timeline, and why you're the right fit. For a small job, an estimate is usually enough.
