LESS GUESSWORK. MORE STRUCTURE.

Make the work clear.
Then make the
numbers add up.

A useful estimate explains the project before it presents a price. Break the work into phases and keep deliverables, assumptions and costs together.

01

Define the deliverables

Give each phase a name and describe the work it includes.

02

Build the cost picture

Add hours, rates and direct expenses, then choose any project-wide adjustments.

03

Check and share

Review a polished preview, export a PDF and keep a local record.

A CLIENT-READY STARTING POINT

A better first impression.
A clearer project conversation.

Present your project in a document that puts the scope and financial assumptions in the right place.

Scope that reads clearly

Organise deliverables by phase and include exclusions so your starting assumptions are visible.

Effort and timing

Keep estimated hours and phase durations alongside the work they support.

Your business identity

Add your logo, business details and brand colour, then choose a clean layout.

FROM A ROUGH BRIEF TO A USEFUL PLAN

Give every phase
a purpose and a price.

Discovery. Delivery. Handover. Whatever your project needs, separate the work into meaningful phases rather than one unexplained figure.

Clients can see the planned deliverables, while you can see the hours, rates and expenses behind the estimate.

SEE THE ADJUSTMENTS

A buffer for uncertainty.
Room for your judgement.

Add a planning contingency, choose your markup and enter the appropriate tax rate. The document shows those adjustments clearly.

Calstro uses the percentages you provide. It does not set market prices, verify tax treatment or promise a project outcome.

GOOD QUESTIONS

Before you build
your next estimate.

What does the Project Estimate Generator do?

It organises project scope into phases, calculates labour and direct expenses, and applies the markup, contingency, discount and tax you enter. You can preview, save and export a client-ready estimate.

Are the suggested rates market prices?

No. Templates use fictional example rates to demonstrate the tool. Replace them with your own approved pricing, costs and assumptions.

How are markup and contingency calculated?

Markup is applied to labour plus direct expenses. Contingency is applied to that adjusted subtotal. The percentage discount then reduces the subtotal, and the tax rate you enter is applied to the result.

Can I print or save a PDF?

Yes. Use Print / PDF in the editor, then choose a printer or Save as PDF in your browser print dialog. Disable browser headers and footers for a clean document.

Is the estimate automatically accepted by the client?

No. Statuses such as Shared or Approved are manual records. The tool does not send, verify, electronically sign or legally accept an estimate on anyone’s behalf.

Where are my estimates saved?

In this browser profile on this device. There is no authenticated cloud account or cross-device sync in this edition. Export backups before clearing browser data.

Can I purchase a subscription?

Plans lead to a checkout review, but live billing and paid account activation are not connected in this package. No card details or payments are collected here.

Does Calstro check tax or project duration?

No. You choose the correct tax treatment. Phase durations are planning assumptions; the summed figure is a sequential estimate and does not account for parallel work, holidays or actual resource availability.
