Home Renovation Budget Calculator | Kitchen, Bathroom Remodel Cost Planner (Google Sheets, Excel)

Description

Worried your renovation will blow the budget? The Home Renovation Budget Calculator tells you what your renovation really costs before you start – and catches overspend room by room before it wrecks your budget. A calculating Google Sheets and Excel spreadsheet (not a blank planner): add every task, and get your total cost, an automatic contingency buffer, and budget vs actual as you go.

What’s inside your Home Renovation Budget Calculator

What It Calculates

• Total renovation cost from every task, by room and by category (materials, labor, permits, fixtures)
• An automatic contingency buffer on top (renovations almost always run over)
• Recommended budget (estimate + contingency) vs your target budget
• Actual spent, % of budget used, and how much is remaining
• Over / under your estimate – and your most expensive room and biggest category

What’s Inside

• Dashboard – total cost, contingency, recommended vs target budget, and budget vs actual, at a glance
• Setup – project name, target budget, and contingency % (10-20% recommended)
• Renovation – every task; pick room and category from dropdowns, enter estimated and actual
• Summary – cost and totals by room and by category
• How it works – a quick guide

Why The Contingency Matters

Here’s the part that saves you: being over your ESTIMATE is not the same as being over your BUDGET. The contingency buffer absorbs the overruns – so as long as your remaining budget stays positive, you’re on track. Most renovation planners skip this. (Always keep 10-20%.)
