🏆 Expense Forecasting and seeing upcoming expenses on a Calendar - UPDATED 4/15/24

Overview

Write a brief description of what the template does.

This template takes a list of recurring bills/expenses, and generates a list of upcoming dates for those expenses.

This template also provides an example of using the generated list of expenses to display the expenses on a calendar.

UPDATED 4/15/24 - I added a way to override individual projected expense payments, so you can modify the date or amount. This is helpful for bills that fluctuate wildly month to month, like utility bills, or if you have a paycheck that includes a bonus once a quarter, you can override the expected amount for that specific paydate, and leave the others at their normal amount.

What is the goal of your workflow? What problem does it solve?

This template allows you to forecast upcoming expenses to calculate expected cashflow.

How did you come up with the idea for your workflow?

I was inspired by this Google Sheets template - 🏆 Generated Recurring Expenses Workflow - but heavily modified it to fit my needs.

Installation

Download the template from here (link).

To install the required sheets:

  1. Add a column to the Transaction worksheet called “Expense Tag”
  2. Open both the Expense spreadsheet and your Tiller worksheet
  3. Right-click the name of the three worksheets in the Expense spreadsheet named Expense Setup, Expense Transactions, Expense Override, and Calendar. Select Move or Copy, and select your Tiller spreadsheet from the drop down list.
  4. In your Tiller spreadsheet, move to the Data tab and click Workbook Links. This will open a window on the right.
  5. Click the three dots to the right of the entry for Excel-Expenses-Tiller, and select Move links. Select your Tiller spreadsheet and click OK.
  6. Move to the Transaction sheet, and highlight the new column you created in Step 1 (Expense Tags). On the Data tab, click Data Validation. Choose List, and set the source to be the Expense column of the table on the Expense Setup sheet.

Setup

There are three worksheets, that each have a few options to configure:

Expense Setup


Fill in the green cells to configure the recurring bills/expenses. The first cell, Active, can be used to stop the expense from being calculated, but preserve the details for later.

Expense Transactions


Columns B and C are used to configure how far back and forward the sheet looks to find a payment that matches the expense.

F2 sets the starting month for calculating the upcoming expenses, relative to the current month. For example, 0 = the current month, -1 would be last month, etc. I leave it at -1, so that expenses at the end of the month that haven’t been paid yet don’t disappear when the first of the next month happens.

G2 defines how many months of expenses are calulated.

H2 controls whether the scheduled date for overdue expenses are recalculated. For example, if an expense is scheduled to happen on 3/15/2024, but it’s now 3/17/2024 and the payment hasn’t been recorded, this option will set the scheduled date to the next day (3/18/2024). If you turn this off, the scheduled due date will remain 3/15/2024. I find this to be really helpful when calculating future cashflow, since the expense hasn’t happened yet, but it’s still pending.

Calendar


This is an updated version of this calender I posted a while ago: 🏆 Showing Transaction Data on a Calendar (Excel version)

B1 and B2 define the month to display.

B3 defines whether the calendar only displays data for the selected month (e.g. April 2024), or for all dates shown (e.g. include March 31)

C6-C11 allow you to set the groups that show summarized transactions on the calendar.

N2-N41 allow you to define the specific accounts you want to be included in the calendar.

Added 4/15/24:
Expense Override

The first column of the table has a dropdown of the current projected expenses. Pick the one you want to override. The next 3 columns will populate automatically. If you want to override the date, enter a new date in the Override Due Date column, otherwise leave it blank. If you want to override the amount, enter a value in the Override Amount column, otherwise leave it blank.

Usage

Once expenses are added to the Expense table on Expense Setup, all you need to do is tag the matching payment transactions on the Transactions sheet in the Expense Tag column. In my Tiller workbook I have them defined in the AutoCat settings to happen automatically, which is really convenient.

The calendar will show the upcoming expenses on the day they are scheduled so you can get a visual representation of when certain bills will happen.

To build your own sheet that uses the calculated upcoming expenses, use the variable name “expenses_upcoming”. This is a reference to a dynamic array on the Expense Transactions sheet, starting in cell M15. You can filter the array as necessary to get only the upcoming expenses you want. For an example of that, refer to cell AE2 on the Calendar sheet to see it in action. You can filter on scheduled date, bill name, amount, account, category, and group. Added 4/15/24 - I also added some additional variable names to make the filtering easier. To reference the individual columns, you can use expenses_upcoming_date, expenses_upcoming_name, expenses_upcoming_amount, expenses_upcoming_account, expenses_upcoming_category, and expenses_upcoming_group.

For example, I have a Dashboard sheet that breaks the upcoming expenses into chunks that align with my paychecks, so I can see how much of each paycheck is pre-allocated to a bill.

FAQ

Optionally, add common questions and answers…

Very nice. I will have to give it a try.

Update: You can ignore this - it took me to close and reopen the file for the updates to be made. Thank you again!

Thank you very much for this. I’m looking forward to getting full functionality. For some reason, I’m having a #VALUE! error with this specific part (CONCAT(expenses,“|”) of the LAMBDA formula. My version of Excel interprets the Expenses table correctly, but upon adding the “|”, it creates the #VALUE! error.

Have you had any other users have this challenge? I’ve been working for a few hours trying to fix the issue, and I can’t seem to resolve it. Thoughts?

I’m using Mac Excel (Microsoft 365) but cannot find the command ‘move links’ under workbook links. Any other Mac Excel users here?

Hi @michael1 - Mac Excel user here. You’ll want to click “Change Source” instead of Move Links. Then you’ll simply select your Tiller workbook, the one that you are copying the solution into. This enables the sheets that were copied in to just use your own Transactions data and not try to link back to the template solution.

I did encounter two issues.

  1. Mac Excel doesn’t allow me for some reason to copy all four sheets at once to my Tiller workbook. It gives an error message to the effect cannot copy multiple sheets containing tables. The resolution is to copy one by one.

  2. Before you do the Change Source step, make sure that you’ve done step 1 and added the new column to the Transaction worksheet. Otherwise it errors because that reference cannot be found. Also very critical is that the actual column name needs to be “Expense Tags”, plural with an “s” at the end. I took me some time to figure that out because it was still erroring until I noticed that the formulas refer to Expense Tags.

Thank you for this! I so look forward to using it. Unfortunately, I’m running into a challenge where I am getting reference errors, like below. Any ideas?

Hi @Phactor, I just realized I forgot to make those dynamic to update if you make any customizations to the Account sheet. It should be looking for the Account column (OOTB column H), and the Hidden column (OOTB column P). Update those references and you should be good.

Thanks, Alan. The new sheets you created are fantastic! I’ve finally figured out all of my errors and everything is working as expected, except for one.

I audited the last three months on the calendar, and every transaction appears as it should. However, when I select the next month (in this case December), the calendar is not populating the upcoming expenses.

I do see the variable name “expenses_upcoming”. on M15 on the Expense Transactions worksheet and the expected transactions for the next six months.

Any suggestions on how to fix?

Hi @Phactor, is the formula in Calendar!AE2 also say “No traansactions”? The formula in Calendar!X2 is to pull in the historical transactions from the Transactions sheet, so that should be empty since you’re looking in the future.

If AE2 is also empty, then it could be one of the filters:

  • The account configured for the expense (from the screenshot it should be First Mid Checking) is somewhere in Calendar!N2:N41
  • The categories of the expenses are not flagged in the Categories sheet to be “Hidden From Reports”

Let me know if it’s one of those things. If not, there might be something wrong with the name variables (expenses_upcoming_date, etc).

Hey @alan.heatherley Apologies for the delay in responding. Some family medi cal stuff got in the way.

Yes, Calendar!AE2 populates with “No transactions”. I’ve also confirmed that the correct account is configured for the expense setup. I’ve also confirmed that none of the expense categories are flagged as hidden.

What I find interesting is that when I view the data on the Expense Transactions tab, the future expenses are projected.

Again, all works perfectly for past transactions on the calendar, so we’re only looking at calendars for future transactions. Where do you suggest I look to identify potential issues with variable names?

Appreciate your expertise, insight, and effort on this awesome addition to my Tiller workbook!

Hi @Phactor, I’m sorry to hear about that! I hope everyone’s health is back where it should be.

I’m honestly kind of baffled, but there are so many ways to customize the Tiller spreadsheet, it’s hard to predict and account for all the possible conflicts. It’s kind of a blessing and a curse.

Why don’t you DM me and we can set up a time to troubleshoot together? I’d love to help sort this out!
