The Traffic Light Budget: the three color system that finally made my money make sense

Some links in this post are partner links. If you sign up through one, TRH earns a little and it costs you nothing extra. I only link to things I use with my own money.

Guarda el orden que el orden te guardará a ti. My abuela did not know she was teaching me budgeting when she said that, but she was.

Here is the honest version of my budgeting history. I made spreadsheets. I made them beautiful. I abandoned every one of them inside six weeks, because a budget with forty categories is a second job and I already had one. The thing that finally stuck had three colors, and I have run my money on it ever since. In the book it is chapter 3, The Budgeting 101 Breakdown, and the system is called the Traffic Light.

Every dollar that leaves your account lands in one of three colors.

Red Zone: the crucial, fixed stuff. The bills that show up every month no matter what. Rent or mortgage, utilities, health insurance, the minimum payments on your debt. If you help family financially, put that here too, on purpose. Remesas treated as a fixed expense are a decision you made, and decisions you made carry no shame.

Yellow Zone: the crucial, variable stuff. Necessary, but it moves. Groceries, gas or the bus, household essentials. You have some control here, and if your grocery number is all over the place, average the last three months and use that as the baseline.

Green Zone: play money, a.k.a. joy spending. Eating out, coffee runs, shopping, hobbies, the streaming stack, nails, the gym. Green is allowed to exist. Instead of feeling guilty about it, you are choosing how much joy you want to budget for. A budget that tries to delete green fails by February.

That is it. Three colors, and one order of operations when you come up short: trim green first, tweak yellow second (hay comida en la casa is a whole movement for a reason), and only touch red as a last resort, with big moves like renegotiating insurance or a phone bill.

Savings and goals sit outside the colors on purpose. In the book the target is roughly 50 percent of take home for red and yellow together, 30 for green, and 20 for savings and goals, and if you live somewhere expensive your needs might sit closer to 60 and everything else adjusts.

Pull up last month's statement. Next to every charge, write R, Y or G. Do not judge yet, just sort. Then add up each color and divide by your take home pay. Three percentages, and they tell you more than any dashboard.

Say your take home is $4,000 and you land at red 45 percent, yellow 20, green 35, with nothing left for savings. Completely normal first result, and it tells you exactly what to do: pick the single largest green line and cut it in half for one month, then move the difference into a savings account the day after payday. One line. You are testing whether you miss it. Most of the time you do not.

If red and yellow together came in above 60 percent, the problem is income or housing, and no amount of cutting green fixes that. That is a different conversation, and it is the one in chapters 14 and 15 of the book.

The sorting is easier when every account is in one place. I run my own money in Monarch Money, which pulls every account and card onto one screen and lets me and my husband see the same numbers. It is the only budgeting app I use or recommend.

For the actual Traffic Light math I built two things. The Mini FinGoals Tracker is free, a Google Sheet for savings goals and debt progress that takes ten minutes to set up. The FinGoals Money System is the full nine tab Excel workbook with the traffic light built in and the Freedom Date Calculator, which tells you the month your debt is gone at your current pace. It is $5 and it works offline, so your numbers stay yours.

The Traffic Light is a structure. Your abuela's recipes fit inside it, your remesas fit inside it, your Costco run fits inside it. The whole point is to see your month clearly enough to decide on purpose, and to keep spending on the people and things you love with your eyes open.

One thing before Friday: the R, Y, G pass on last month. Twenty minutes. Then post your three percentages in Money Wins at Hermana HQ, the free room where people compare notes on exactly this: https://mail.therichhermana.com/community/channels/money-wins

If you want the tracker sent to your inbox instead, comment GAME PLAN on any of my Instagram posts and I will send it to you. And every Tuesday I send one letter with one money move, written like a text from your rich big sis. The button below gets you in.
