Most renos blow out by 20–40%. The right app won't stop surprises — but it will make sure you see them coming.
Planning a renovation is exciting right up until the first quote lands. After that it's a lot of spreadsheets, lost emails, and the slow creep of costs you didn't see coming.
These six tools tackle the budget problem differently. Some are built purely for tracking spend; others fold budgeting into a wider project management platform. None of them will stop a tradie hitting you with a change order at 4pm on a Friday — but they'll at least mean you're not surprised by the total.

Budget My Reno does what it says: a web app built specifically for tracking renovation costs. No project management overhead, no floor plan tools. Just a budget tracker with a clear purpose.
The free plan covers budget creation, expense tracking, and categorisation across unlimited projects. Premium adds AI receipt scanning (photograph an invoice and it auto-populates your budget), contractor invoice schedules, an audit trail of all changes, and project sharing so your partner or builder can see where things stand. At US$2 a month, it's cheaper than a coffee.
The interface is clean and quick to learn. Visual category snapshots show where the money is going, and the budget vs. actual tracker updates in real time. It works across desktop and mobile, which matters when you're standing in a tile showroom trying to remember if you've still got room in the flooring budget.
Pros
- Designed exclusively for reno budgeting
- AI receipt scanning saves significant data entry
- Works on any device — no app download needed
- Clean, intuitive UI with minimal learning curve
- Collaborative sharing with contractors or partners
- Generous free tier with unlimited projects
- Audit trail keeps everyone accountable
Cons
- No cost estimation or contractor directory
- No 3D design or floor plan features
- Primarily UK-focused (currency/market)
- No native iOS/Android app yet
Free core features
Pro Report: paid add-on
Web
Remodelum covers two things most apps treat separately: cost estimation before you start, and budget tracking once work begins. The estimator uses zip-code-level data to break costs down by category — labour, materials, permits — which is more useful than a national average that has no idea what trades cost in your suburb.
Once construction starts, that estimate becomes a live budget. Log invoices, track contractor payments, flag change orders, and compare actual spend against plan. The contractor quote comparison tool is the standout feature — it puts bids side by side in a consistent format, so you're not trying to reconcile three documents that don't use the same line items.
Core features are free. A Pro Report — an itemised PDF with full material and labour breakdowns — is a paid add-on. Worth it if you need something structured enough to share with a builder or present to a lender.
Pros
- Covers both estimation and live tracking
- Zip-code accurate cost estimates
- Side-by-side contractor quote comparison
- Change order and invoice management
- Home improvement record for resale documentation
Cons
- Cost estimator is US-centric (zip-code model)
- Detailed reports require a paid upgrade
- Interface less polished than some competitors
- No mobile app; web-only

Google Sheets / Excel
Etsy has hundreds of renovation budget spreadsheets, and some of them are really good. Top-selling templates usually include room-by-room trackers, contractor payment schedules, contingency calculators, and summary dashboards — formulas built in, ready to use.
The case for buying one is straightforward: you pay a few dollars once, you own it forever, and it lives in Google Sheets or Excel where you already know your way around. The better templates are detailed and clearly built by people who've actually done a renovation.
The limitation is the same as any spreadsheet. No auto-sync, no receipt scanning, no audit trail. Sharing means emailing a file around. If your project is relatively contained and you're comfortable in Excel, an Etsy template is good value. If you're managing multiple trades across several months, you'll probably outgrow it faster than you expect.
Pros
- Very low one-time cost
- Highly customisable — it's just a spreadsheet
- No subscription or login required
- Works in tools you already know
- Many templates reflect real reno experience
Cons
- No automation or receipt scanning
- Manual data entry throughout
- Quality varies enormously between sellers
- No audit trail or version control
- Collaboration is clunky via file sharing

HomeZada is the biggest tool on this list, and that's both its strength and its problem. It's not really a renovation budgeting app — it's a whole-of-home management platform. Renovation tracking sits alongside property maintenance scheduling, warranty storage, home insurance records, home value forecasting, and monthly cash flow tracking across mortgage, utilities, and rates.
For renovations specifically, it lets you plan from itemised estimates, compare DIY vs. contractor costs, manage bids and contracts, and track receipts. The Premium tier adds AI photo analysis and smart home device integration.
If you want one app to manage your property for the next decade, HomeZada is worth a look. If you just need to track a bathroom reno, it's a lot to take on. Most people trying it for the first time spend the first hour figuring out where everything is.
Pros
- Covers the entire homeownership lifecycle
- Maintenance scheduling with reminders
- AI photo analysis (Premium)
- Smart home device integration
- Document storage for warranties and receipts
- Native iOS and Android apps
Cons
- Can feel complex for a single reno project
- Annual subscription adds up vs. free alternatives
- US-centric features (home value integration)
- Steeper learning curve
Free templates available
Paid templates: ~AU$5–AU$75 (one-off)
Web, iOS & Android
If you already use Notion for work, adding a renovation template to your workspace makes sense. The Notion Marketplace has free and paid home renovation templates, and third-party creators on Etsy and Gumroad have built more detailed options for a small one-off fee.
The good paid templates (roughly AU$10–AU$75) include linked databases for projects, expenses, and service providers, automatic budget vs. actual calculations, contractor management, and room-by-room breakdowns. Because it's all in Notion, you can connect your reno budget to task lists, timelines, and notes — handy if that's already where you run everything else.
The catch is the same as with Etsy spreadsheets: it's still manual data entry, quality varies between creators, and if you've never used Notion before, there's a learning curve before it feels natural. But for existing Notion users, being able to add custom fields, filters, and views — and connect your reno budget to the rest of your workspace — is something no purpose-built app gives you.
Pros
- Fully customisable — reshape to any workflow
- Integrates with the rest of your Notion workspace
- Free templates available on Notion Marketplace
- Paid templates are detailed and low one-off cost
- Works across web, iOS, and Android
- Design boards, task tracking, and notes in one place
Cons
- No automation or receipt scanning
- Requires a Notion account (free tier available)
- Template quality varies widely — research before buying
- Manual data entry throughout
- Learning curve if you're new to Notion

New: Renovately AI co-pilot
Renovately takes a task-first approach. Instead of starting with a spreadsheet, you start with the work — to-do lists, to-buy lists, progress checklists — and the costs roll up into a budget automatically at the task and project level. If you think in terms of "what needs doing next" rather than "what's the line item", it clicks faster than most.
Version 6.0, released May 2025, added Renovately AI — a chat assistant built into the app that can suggest task lists for common renovation types, help with design ideas, and give rough budget guidance. Real-time cost tracking and variance summaries also got an overhaul in the same update, which makes the numbers side more useful than it was in earlier versions.
It also does mood boards, progress photos, contractor tracking, and due-date reminders. The main limitation is it's iOS only — no Android, no web version. And with only one review on the Australian App Store, it's hard to know how it holds up on a real project. Worth trying on a smaller job before committing to it for a full build.
Pros
- Task-centric design feels intuitive for DIYers
- AI co-pilot for design ideas and task generation
- Mood boards and progress photos built in
- Budget rolls up automatically from tasks
- Native iPhone and iPad app (iOS 15.1+)
- Free to download with no upfront cost
Cons
- iOS only — no Android or web version
- Very few reviews on the AU App Store (limited track record)
- In-app purchases required for full feature set
- Less suited to complex multi-trade cost tracking

Which app is right for you?
Honestly, the decision mostly comes down to where you're starting from. Already in Notion? Use a Notion template. Live in Excel? Buy an Etsy spreadsheet. On iPhone and want everything in one place? Try Renovately on a small project first.
If you're starting from scratch with no strong tool preference, Budget My Reno is the most focused option — it's built for exactly this job, costs almost nothing, and the 30-day free trial means you can test it properly before committing. Remodelum is worth adding if you're in the US and need to estimate before you've spoken to anyone. HomeZada is the only one worth considering as a long-term home management platform rather than just a reno tracker.
Whatever you use: build in a 15–20% contingency, and set it up before the first tradie arrives. The worst time to start tracking is after the first invoice lands.
Prices correct as of May 2025. Always check app websites for current pricing and availability.
