Free Renovation Budget Spreadsheet

Template structure + a better way · 2026

The short version: a renovation budget spreadsheet is a fine place to start. Below is a structure you can copy into Google Sheets or Excel in a few minutes — the categories and the columns that actually matter. We'll also be honest about where a spreadsheet stops being enough once the work is underway, and what to use instead.

If you searched for a free renovation budget spreadsheet, you already have the right instinct: get the numbers out of your head and into a grid. The good news is you don't need to download anyone's locked-down template — the structure is simple, and building it yourself means you understand every cell. Here's the layout that works.

The columns that matter

Most people make a spreadsheet with two columns — item and cost — and that's exactly the version that quietly goes over budget. The useful version separates what you plan from what you've committed from what you've paid:

Column	What it holds
Category	Plumbing, Electrical, Kitchen, etc.
Item	The specific job or order
Budget	Your planned amount
Committed	Quotes accepted / orders placed (money owed)
Paid	Money actually sent
Remaining	Budget − Committed (your real exposure)
Notes	Contractor, dates, anything useful

The one formula to add: in Remaining, use = Budget − Committed, not Budget − Paid. Tracking against committed money is what shows trouble coming, because a quote you've accepted is already spent even though the cash hasn't left yet.

A starting category list

Create one row block per category and sub-total each. A typical renovation budget spreadsheet covers:

Demolition & prep (strip-out, skips, protection)
Structural (walls, beams, openings, engineer fees)
Plumbing (first-fix, drainage, fixtures)
Electrical (rewire, sockets, lighting, certs)
Plaster & decorating
Kitchen / bathroom (units, worktops, appliances, sanitaryware)
Flooring & tiling (materials + labour)
Fees & permits (design, building control, surveys)
Contingency (a reserve — see how much to set aside)

Add a grand-total row at the bottom that sums the category sub-totals, and a "remaining vs budget" cell so you can see the whole picture at a glance.

Where spreadsheets fall short

A spreadsheet is great for planning and terrible at the part that actually keeps you on budget: staying current while the work happens. In practice, the cracks show up fast:

It doesn't follow you to site. The payment you made at the merchant on Tuesday gets logged "later" — and later is where budgets die.
No cash-flow view. A spreadsheet that balances overall can still hit you with three big payments in the same week. It won't warn you.
Fragile formulas. One deleted row or dragged cell and the totals are quietly wrong.
No schedule. Money and time are the same problem in a renovation; a budget sheet ignores the calendar entirely.
Contingency drift. It's easy to forget to deduct a draw, and a stale reserve number gives false confidence.

The same idea, built for a live project

Storypole takes the spreadsheet structure above — categories, committed vs paid, a contingency buffer — and makes it a live tool: it forecasts your cash flow, keeps a critical-path schedule next to the money, works offline in your pocket on site, and can't be broken by a stray cell. It's free for one project, with no account, and your data stays on your device. You can still export to Excel any time.
