How to use this tool
Create a clear estimate
Set out expected project or goods costs before every detail is confirmed. Start with a blank document or load the local sample, check the preview, then print or save a PDF. Download a JSON backup separately when you want to restore an editable draft.
This free estimate maker builds a clear, professional cost estimate in your browser: describe the work, add labour and material lines, state your assumptions, and set how long the numbers stay valid. The live preview shows the finished document as you type, so what you send is exactly what you checked.
An estimate is normally used as an early calculation rather than a final bill. The generator keeps its assumptions, allowances, and validity date visible so the recipient can see what may still change. Its legal effect depends on the wording, acceptance, and applicable law.
What is this document?
This estimate is a business document used when you need to explain an early cost calculation, assumptions, and validity period. Set out expected project or goods costs before every detail is confirmed.
When to use it
Use it when you need to explain an early cost calculation, assumptions, and validity period.
Use a different record when
a final request for payment or a confirmed commercial offer.
1. Add the essentials
- Sender and recipient
- Document number and dates
- Accurate line items
- Valid Until
- Scope Assumptions
2. Review before sharing
Use the live preview to check names, dates, amounts, layout, paper size, and the fields that matter for this document.
3. Keep a backup
Local browser storage is convenient, not a backup. Download a backup file when you need a portable copy, then store it somewhere you control.
Field-by-field check
- Business and recipient details: use the names and addresses that belong on the record.
- Estimate Number: keep this reference unique and retain it with the related record.
- Line items: check the description, quantity, rate, tax mode, and tax rate before printing.
- Valid Until: complete this document-specific field when it applies.
- Scope Assumptions: complete this document-specific field when it applies.
A practical estimate example
A contractor estimates labour, materials, optional allowances, and the date until the estimate is valid.
Start from a completed local example
Select Load Sample in the editor to populate a completed example for this tool. Review it against your own record, then use Export to print or save a PDF. Choose a JSON backup separately to preserve an editable Formnivo draft.
How the next document differs
- Quote: Present scoped pricing and terms for customer acceptance. Create it only when the next business event has actually occurred.
- Work Order: Scope, schedule, and details for field service technicians. Create it only when the next business event has actually occurred.
- Invoice: Request payment for completed goods or services. Create it only when the next business event has actually occurred.
Common mistakes to avoid
- Using this estimate when it is not the right record. Use it when you need to explain an early cost calculation, assumptions, and validity period.
- Printing before checking names, dates, currency, paper size, tax labels, and totals in the preview.
- Relying on browser storage as the only copy. Export a JSON backup before clearing site data or changing devices.
Official country-source notes
Requirements change by jurisdiction. Use the country selector in the editor, then verify applicable rules with the relevant authority before relying on this document.
Choose a country in the country registry to see only that jurisdiction's reviewed scope, official sources, and research limits. The full source register remains available for audits; unrelated country sources are intentionally not attached to this generator.
Is this estimate generator really free?
Yes. Every part of the tool - editing, templates, and PDF or image export - is free, with no account, no watermark, and no trial limit. The editor runs entirely in your browser and your estimate data stays on your device.
What should an estimate include?
A clear scope description, itemised labour and material costs, any allowances or exclusions, the assumptions the numbers rest on, a validity period, and your business and customer details. The generator provides fields for each so nothing is left implied.
What is the difference between an estimate and a quote?
An estimate communicates an approximate cost before every detail is confirmed. A quote presents a clearer offer for acceptance, although its legal effect still depends on its terms and applicable law. If scope and price are ready for acceptance, use a quote instead.
Can I turn an estimate into an invoice later?
Yes. The workspace can carry an estimate forward into an invoice, keeping the parties, line items, and references so you do not retype them. The estimate itself stays unchanged as your record of what was originally proposed.
How do I download my estimate as a PDF?
Select Export in the editor and choose PDF. You can also export PNG, JPG, WebP, or SVG, control the resolution, and download an editable JSON backup so you can reopen the estimate on any device later.
Do estimates need a validity date?
A validity date helps the recipient understand how long the assumptions and prices remain current. Choose a period that reflects how quickly your labour, material, and supplier costs may change, and state it on the document itself.
Does this tool make a document legally or tax compliant?
No. It helps you prepare a clear document, but requirements vary by jurisdiction and situation. Check the relevant authority and a qualified adviser when compliance matters.
Where does my document data go?
The editor works locally in your browser. Read the privacy notice and how local-first document handling works before relying on a document.
