I Entered the 2019 Tiller Builders Challenge

I'm a money nerd, and I love building a good budget spreadsheet. It was only natural that I entered the 2019 Builders Challenge by Tiller. Tiller feeds your banking information, like balances and transactions, into a Google Sheet. Tiller isn't free but is priced in line with other top-notch budget tools.

The goal of the Builders Challenge was to inspire the creation of impactful personal finance solutions based in Google Sheets.

The Goal

Don’t we all just want to know how much we can spend today? How is that impulse buy going to affect your cash flow for the month? How does your spending affect how long it will take you to pay off your debt?

Well, look no further because this budget workbook answers those questions and so much more!

This template can help you:

  • Track your spending by category over time

  • Tell you how much you have left to spend for the month & day-by-day

  • Breakdown how much you planned to earn and spend, compared to how much you have so far

  • Show a simple view of your monthly budget by fixed or flex expenses

  • Display your total income and expenses for the last 12 months

  • Check off bills as they are paid or scheduled

Fixed v. Flex Expenses

Fixed expenses are those that are close to the same amount every month. Things like your utilities, rent, insurance, and childcare. Once these items are paid - just check them off for the month!

Flex expenses are things that you have some control over how much they are, like your groceries or transportation costs. This category also includes expenses you could do without, but are a part of your routine. Think coffee trips, shopping, and eating out.

By tracking these types of expenses separately, you’re can quickly see what you can cut back on if needed. It's the separation your detailed budget needs.


With the savings tracker and savings over time chart, you can quickly see what your savings account will grow to in a year.

This sheet is smart enough to include your employer match, grow each account by a different rate, and show the growth of your savings over time.

This template can track up to 20 savings accounts.

Have debt?

This sheet compares 3 strategies to pay off your debt:

  • Minimum Payment

  • SnowBall

  • SnowBall that adds extra payments that update as your leftover cash does (as you’re spending!).

It’ll even show you the payments and balance overtime by strategy.

Using the debt tab, you can update extra payments by month. For months that you need more to spend - reduce it, for months you can send more - increase it!

This template can track up to 20 debts.

I have coached hundreds of people, and this sheet reflects that experience. Some of my clients need help just spending less than they make, others have debt they are working to pay off.

This sheet was born from my 4+ years working with and listening to the needs of everyday Americans.
