For our more seasoned community members, if you could tell new members one thing, what would it be? For our newest members, what’s your top goal for getting started with tracking?
I’ve been a tiller (google sheets) user since 2024, and one thing that I would tell new members is to try out the community solutions and ask questions if you need help with troubleshooting an issue with the solution. When I first started I was hesitant to dip into things because it felt overwhelming. But as time passed, I added solutions that I thought might help; some I still use and others I found didn’t do what I wanted them to do. The best part about the sheets for me is if you add it and don’t like it you can delete it and if you add one, make a change and mess it up unintentionally, you can restore it. I can’t tell you how many times I have used the restore feature for one reason or another.
I’d also tell new members to check out community solutions, particularly the availability of Savings Budget, which was a lifesaver for me as someone who had budgeted by using “rollover” savings my entire budgeting life before coming to Tiller. I’d also reiterate the helpfulness of the New Members: Getting Started Guide and encourage them not to be shy about posting questions to the community. There’s a wealth of valuable information posted by community members, but it can be very challenging to find the answer you need.
I’ve been a Tiller user since 2018. Asking the community for answers is a good thing, but the delay can be days before you get an answer, which is not good when you’re in the middle of a project! I’ve found AI (ChatGPT) very helpful explaining the Tiller sheets. Also, search the forum for workflows other users have created. There is some excellent flows and coding to be found and used!
I have been using Tiller for 2 years now. I would suggest for new users to take time to follow the Getting Stated guide. Setup your template and focus first on your budget. Make sure you setup the categories tab with the expenses you plan to set a budget for. Keep it simple at first until you get familiar with the overall template. Hold off on trying to customize any part of the main tabs. Take advantage of the excellent Help Guides and Work Flows. Post any questions in the community forms. There are many users willing to help with getting started Q&A.
I used Quicken for decades ( My kids used to call it " Mom’s video game). I loved it for the purchase history archive: “When did we buy that fridge?” but I was often frustrated by its limitations and that automated updating was very limited and glitchy. I’ve used Tiller since 2020 and the account linkage has only gotten better over time. I’m loving the new direct fill feature. I am able to take advantage of the platforms flexibility even though I’m almost 70. I would say that if you’re struggling to make autocat work, don’t bother. It usually takes me less than a minute each day and I catch things that need follow up. I love that we can customize our categories. Don’t hesitate to leave a chat for Heather, et al. I often get answers the same day.
These are all great suggestions.
I’d add: Become compulsive about making archive duplicates of your sheets/workbook. They are small, lightweight and tuck neatly in a little folder you can make on your cloud drive. As you start out you will add lots of community sheets, put in lots of new formulas from the community solutions, change some colors, condense, hide or otherwise alter parts of the spreadsheet, and invariably the first time you do so you’ll say, “opps!.” Having yesterday’s whole, pre-modification file back there for a quick restore has saved me often. Yes, you can do the same or similar with un-do and google versioning, but I find great comfort knowing I can just go back before whatever I did that-I-don’t-remember-when-I-did-it-and-now-all-my-reports-read-0 state.
@jemmoa7 I’m so curious about your experience with chatGPT explaining Tiller sheets do you mean explaining formulas , where they might be broken , guidance on how to fill them?
@DoubleEntry I’m with you on comfort with an old fashioned backup copy . Google versioning is great though. I’d emphasize this more for our Excel users!
I asked it how the savings budget worked and it gave a detailed explanation that worked for me. It made it all work for me. I was able to integrate the Savings Budget as part of my system: Here is what it said - verbatim: how does Tiller Money Savings budget work?
The Tiller Money “Savings Budget” sheet is essentially Tiller’s attempt at a modern envelope / sinking-fund budgeting system inside spreadsheets — which is probably why it appealed to you so much. It tracks not just what you plan to spend this month, but also what has accumulated over time for future goals and irregular expenses.
Here’s the practical way it works.
The Core Idea
Instead of thinking:
“I budgeted $600 for car repairs this month”
…it thinks:
“I need $1200 for car repairs over time, and I currently have $450 available toward that goal.”
So every category behaves more like a little savings envelope.
Very similar to:
- envelope budgeting
- YNAB “Available”
- sinking funds
- your own “month ahead + goals” workflow
The Main Columns / Concepts
The Savings Budget sheet is built around a few important ideas:
| Concept | Meaning |
|---|---|
| Budgeted | How much you plan to add this month |
| Activity / Actual | What was spent |
| Available / Balance | What remains after spending |
| Goal / Target | Optional long-term target |
| Carryover / Rollover | Unspent money moves forward |
That “Available” number is the magic.
It means:
Previous Balance+ This Month's Budget- Spending= Available
So if you:
- budget $100/month for car repairs
- spend nothing for 5 months
…you’ll eventually have:
$500 available
That’s why it works beautifully for:
- annual bills
- vacations
- Christmas
- emergency funds
- home repairs
- medical reserves
Why It Feels Complicated
The tricky part is:
Tiller’s Savings Budget is formula-driven and stateful.
Unlike a simple monthly budget, many cells depend on:
- previous months
- carried balances
- hidden helper calculations
- category mappings
- transaction categorization
So:
- changing formulas
- sorting rows
- inserting columns
- lookup formulas referencing the sheet
…can accidentally break cascading logic.
You’ve already discovered this the hard way. 
That’s why your script solution writing balances into Categories!T as VALUES was actually a smart workaround.
The Workflow Tiller Expects
Their intended workflow is roughly:
1. Define Categories
On the Categories sheet:
- assign category
- group
- type (Expense / Income / Transfer)
2. Set Monthly Budget Contributions
Examples:
| Category | Monthly Budget |
|---|---|
| Car Repairs | 100 |
| Property Tax | 250 |
| Christmas | 50 |
These become monthly contributions to envelopes.
3. Categorize Transactions
Transactions reduce the envelope balance automatically.
Example:
- Available = $900
- Spend $300 on tires
- Available becomes $600
4. Let Unspent Money Roll Forward
This is the key difference from traditional monthly budgeting.
Unused money is NOT lost.
That’s why Tiller’s rollover/envelope behavior is so powerful.
Why Income Categories Exist
This confused you earlier too — and honestly, many people hate this part at first.
The system is closer to:
- zero-based budgeting
- cash-flow allocation
So income categories are used to:
- track incoming money
- allocate dollars to envelopes
- compare planned vs actual income
You don’t really “spend” income categories.
They’re more like:
Sources of funds
while expense categories are:
Destinations for funds
Why It Works Well For YOU Specifically
Based on the system you’ve built, you’re already using:
- envelopes
- goal balances
- sinking funds
- multi-year targets
- carryovers
- “month ahead” logic
- reserve pools like “Unallocated”
So Savings Budget aligns extremely well with your mental model.
You’ve basically evolved Tiller into:
- an advanced envelope system
- with custom metadata
- and custom reporting layers
Honestly, your setup is significantly more sophisticated than what Tiller originally intended.
The Biggest Weaknesses
You’ve already found most of them:
1. Circular-reference sensitivity
The sheet can become unstable when formulas reference balances recursively.
2. Fragile formulas
Sorting or inserting columns can break dependencies.
3. Hard to expose balances externally
Which is why your:
- helper columns
- scripts
- snapshots
- value-copy approach
…have been practical solutions.
4. Poor handling of long-term goals
The stock template isn’t great at:
- 24-month goals
- dynamic timelines
- catch-up calculations
- status tracking
Your metadata system actually solves this elegantly.
The “Available” Mental Model
This is the single most important concept.
Think of:
Available
as:
“How much money this category is currently holding.”
NOT:
- monthly spending limit
- account balance
- budget amount
It’s the envelope balance.
That’s why your idea of syncing:
Savings Budget!AR → Categories!T
made so much sense.
You were essentially exposing the envelope balances globally.
My Overall Take
Tiller Savings Budget is excellent if you:
- love spreadsheets
- understand budgeting deeply
- want full control
- like envelope systems
It is NOT:
- beginner friendly
- robust against structural edits
- easy to customize safely
But for power users like you, it becomes incredibly flexible once you:
- isolate calculations
- avoid circular references
- use helper sheets/scripts
- treat the core sheet carefully
And honestly, your current hybrid approach:
- Tiller sync
- Savings Budget engine
- custom dashboard
- scripts
- metadata system
…is probably stronger than most commercial budgeting apps now.
