Learn How to Budget! Personal Budgeting Made Easy in 16 minutes!
BrainyMoney And Son Han, CFA,CPA · Personal Finance Made Easy!
A 20-minute Google Sheets walkthrough that gets a first budget 90% done, but only if you already trust the spreadsheet.
This class has one job: get a first-time budgeter from a blank spreadsheet to a finished monthly budget in under 20 minutes. It does that job, and it is honest about how narrow the job is.
The structure is a six-step walkthrough layered directly onto a pre-built Google Sheet. Step one calculates net worth by listing assets (home value, car values, checking, savings, retirement accounts) against liabilities (mortgage, auto loans, credit card, student loan), with the sheet auto-totaling as numbers go in. Step two builds expense categories, step three builds income categories, step four logs actual transactions against both, and step five generates an actual-versus-budget summary with a savings rate and category-by-category variance. Step six is just exporting that summary to PDF. Each step is its own short video, which makes the course easy to pause and work through live rather than watch passively.
The one real technique worth taking away
The most useful instruction in the whole course is also the simplest: round every number to the nearest $10 and stop chasing exact cents. The instructor frames this against a 90%-accuracy target for a first pass, explicitly rejecting the instinct to enter $109.38 for car insurance instead of $110. Combined with the promise that the budget gets revised monthly, this reframes budgeting as an iterative habit rather than a one-time precision exercise, which is exactly the mental block that stops most people from starting at all.
The worked example that runs through every step doubles as a light template for real numbers: a mortgage, two car payments, a personal loan, groceries, dining out, and a short list of recurring subscriptions grouped into one miscellaneous line. Income is limited to a main paycheck, one side hustle, and a small interest/dividend line, using net pay rather than gross, since only take-home money is spendable. That choice is correct and worth internalizing on its own.
Where it falls short
The course leans entirely on a proprietary spreadsheet that must be copied before anything works, so the lesson is inseparable from the tool. Nothing here explains the underlying logic well enough to rebuild in Excel, Notion, or any other system, and no lesson addresses irregular income, multiple bank accounts, joint households beyond a single renamed category, or a strategy for deciding which debt to attack first. The net worth math itself is straightforward addition and subtraction, nothing that requires 20 minutes of instruction beyond knowing where to find a mortgage balance or a Kelley Blue Book estimate.
At the length offered, that is a fair trade. This is not a personal finance education, it is a fast on-ramp into a specific habit, and it succeeds at making that first budget feel achievable rather than paralyzing. Anyone who finishes it will have a real, usable budget. They just won't understand budgeting any better than before they started.
The standout
The round-to-the-nearest-$10 rule, paired with the explicit 90%-accuracy target, removes the perfectionism that stalls most first-time budgets.

- How to calculate net worth by listing assets (house, cars, cash, retirement accounts) against liabilities (mortgage, car loans, credit card, student loan)
- How to build expense categories rounded to the nearest $10 instead of tracking exact cents
- How to set up income categories using net (after-tax) pay rather than gross income

- How to export the finished budget as a PDF for the class project submission
Best for: A total budgeting beginner who wants a done-for-you spreadsheet and a fast, low-friction first pass rather than a from-scratch build.
Skip it if: Anyone who already budgets, wants to build their own spreadsheet logic, or needs guidance on irregular income, debt payoff strategy, or joint-account nuance.
