A small set of spreadsheets built for the jobs our free calculators start. Every one is a real Excel file you own. The calculators themselves stay free and unlimited — these are just the tools that sit on top of them.
Home Renovation Budget & Materials Workbook
Plan the whole job in one spreadsheet
A five-tab Excel workbook that turns a pile of measurements into a priced, scheduled renovation plan.
- 36 material lines with waste allowances already set
- Live roll-up: materials, labour, self-build time, contingency, total
- 14-task schedule with weekend-aware dates and slip tracking
Kitchen Remodel Planner
Cabinets, appliances, trades and a sequence — priced before you sign
A six-tab Excel workbook that turns a kitchen design into a priced budget with a dated work sequence.
- 14 cabinet and countertop lines with per-line waste allowance
- 11 appliances with a replace-or-keep column for staged buying
- 12 trades — hours × rate or flat lump sum, same table
Bathroom Remodel Planner
Rough-in, tiling, ventilation — the room where the mistakes are hidden
A seven-tab Excel workbook covering rough-in, fixtures, tiling, ventilation and a dated sequence for one bathroom.
- Rough-in tab covering waste lines, shower valves and soil pipes
- Every tiling line flagged for waterproofing — wet zones can't be forgotten
- 14 fixtures with a separate fittings column so tap sets aren't hidden
Renovation Contract & Change Order Tracker
The spreadsheet you hand a contractor on day one and keep for the whole job
A four-tab workbook that tracks scope, variations, payments and your true money position across a renovation.
- 16 priced scope lines with reference numbers for every email and conversation
- 8 change-order rows: reason code, approval flag, value
- Only rows marked Yes count toward your revised contract sum
Before you buy
- Delivery. Each workbook is a downloadable .xlsx file. You get a download link on the order confirmation page straight after payment, and a copy by email.
- Format. Files open in Excel, Google Sheets, LibreOffice and Apple Numbers. Nothing needs installing and nothing needs an internet connection afterwards.
- Refunds. If the file turns out not to be useful to you, email us within 14 days of purchase and we will refund it. No questions, no forms.
- What these files are. Planning tools that produce estimates. They are not quotes, contracts, or professional construction, engineering, financial, tax or legal advice. Prices, rates and regulations change — confirm anything that matters with your supplier or a qualified professional before you rely on it.
- Your calculators stay free. Every calculator on BuildCalc remains free and unlimited. Buying a workbook does not unlock, remove or change any of them.
- Questions or a bug. Email hello@buildcalc-hub.com — we answer within three business days.
