What This Does

Builds a reusable, formula-driven estimate template with automatic calculations for materials, labor, markup, and profit — so every future estimate starts from a consistent structure instead of a blank page.

Before You Start

  • You have a Google account (free)
  • You can access Google Sheets at sheets.google.com
  • You have a rough sense of the line items you use most often in estimates

Steps

1. Open Google Sheets and find the AI feature

Open a new Google Sheet. In the top-right corner, look for the Gemini icon (a small sparkle/star icon) or click Extensions → Gemini in Sheets to open the AI sidebar. On mobile, tap the three-dot menu and look for Gemini.

2. Tell it what to build

Click into the AI sidebar and type:

Prompt

"Create a residential remodeling estimate template with sections for: Demo, Carpentry/Framing, Plumbing, Electrical, Tile Work, Painting, and Miscellaneous. Each section should have columns for: Item Description, Quantity, Unit, Unit Cost, and Total. Add a Summary section at the bottom that calculates Subtotal, Overhead (15%), Profit (10%), and Total Project Cost."

Click Generate or Insert.

3. Review and customize the result

The AI will generate a structured sheet with formulas already in the Total column and Summary section. Check that:

  • The Summary section correctly references all line item totals
  • The percentage formulas for Overhead and Profit calculate correctly (test with a sample number)
  • The column widths are readable

Adjust overhead and profit percentages to match your actual targets.

4. Add your standard line items

In each trade section, pre-populate the Item Description column with your most common line items. For example, under Tile Work: "Tile material — floor," "Tile material — walls," "Cement board," "Grout and setting materials," "Labor — tile installation."

5. Protect the formulas and save as template

Right-click the formula cells → Protect range to prevent accidental deletion. Then go to File → Make a copy and name it "ESTIMATE TEMPLATE — MASTER." This becomes your starting point for every new estimate.

Real Example

Scenario: You're estimating a bathroom remodel and want a consistent starting structure.

What you do: Open the master template → File → Make a copy → Rename to "Smith Bathroom — 2026-03-19." Fill in your scope items with quantities and unit costs. The Total column and Summary section calculate automatically.

What you get: A complete, branded estimate with automatic calculations — ready to screenshot or PDF and attach to your proposal email.

Tips

  • Add a "Notes" column to the right of each section for items that need clarification before you can price them
  • Include a cell at the top for "Client Name" and "Project Date" — these can be referenced in a header row to make each estimate feel bespoke
  • Duplicate the sheet tab and rename it "Budget Tracker" — use the same line items but add an "Actual Cost" column to track job performance

Tool interfaces change — if the Gemini icon has moved, look for similar AI/magic/smart options in the Extensions or Tools menu.
