Three accounts, no categories: the simplest money system for ADHD

Picture one checking account, the way most people start out. It works the way a single drawer works when you put everything you own in it. Rent comes out of it. Coffee comes out of it. A paycheck or a client payment lands in it, and for a week you feel rich, and then the insurance or the quarterly tax estimate comes out of it and you feel the opposite. You never know what's yours to spend, because everything is in the same place and every number is a guess.

Budgets try to fix that by giving you twelve numbers instead of one, and a brain that can't hold one number can't hold twelve any better.

What works is the opposite move. Fewer numbers, more accounts. Three of them, with strict jobs, and a set of transfers that happen on payday without you. We've watched some version of it hold for years, through good stretches and low ones, for people whose brains regularly lose their keys. It's the system at the center of The ADHD Money Guide, and here's the whole thing.

Why categories are the problem

Every money system that's failed you has probably had categories. Groceries, gas, dining, fun, clothes, subscriptions. Categories feel responsible. They're also the exact feature that kills the system, because they require two things a brain like this does badly: looking often and sorting accurately.

Every purchase becomes a small filing task. Was that coffee "dining" or "fun"? Was the pharmacy run "health" or "groceries" because you also bought bread? Each decision is tiny, and there are dozens a week, and each one is a place to stall. After enough stalls, you stop filing, and once you stop filing, the categories are wrong, and once they're wrong the whole system is lying to you and you stop looking.

The fix is to move the sorting out of your head and into the structure. Instead of categorizing purchases, you separate money before it can be spent. Then there's nothing to file.

The three accounts

Open three accounts at the same bank, so transfers between them are instant and free. Most banks let you do this online in an afternoon. Name them, if the bank allows it, because the names are half the system.

Bills. This is where every fixed, recurring payment lives. Rent or mortgage, utilities, insurance, phone, loan minimums, the subscriptions you've decided to keep. All of it on autopay, drawing from this account. Nothing else touches it. No card is attached to it. You never spend from it, and between paydays you don't even look at it.

Spending. This is the account with a card. One card. Groceries, gas, coffee, dinner, the thing you want, all of it comes from here. The rule is that you're allowed to spend it to zero. There's no category to check, no math to do. If the balance is there, you can buy it. If it's not, you can't, and the answer is that clear.

Buffer. This is the cushion. It exists so that a timing mistake, a bill that hit a day early or a paycheck that landed a day late, can't bounce anything. Think of it as executive function kept in cash form. Other people's brains remember that the insurance comes out on the 3rd. Yours has a buffer that doesn't care. The buffer sits next to Bills, not next to Spending, because its job is to protect the autopay, not to fund a Saturday.

There's an optional fourth account, Someday, for the predictable surprises: car repairs, the dentist, holidays, annual insurance. One fixed transfer a month, sized to last year's total divided by twelve. But the three above are the system. Start there.

Payday routing

Here's where the decide-once principle does its work. On payday, before you can touch the money, fixed amounts move automatically.

A set amount goes to Bills. A set amount goes to Buffer. The remainder goes to Spending. That's the routing, and it's set up once as scheduled transfers at your bank, or as split direct deposit if your employer offers it.

To calculate the Bills amount, add up everything on autopay for a month. Divide by the number of paydays you have in a month. Add roughly ten percent for the things you forgot to list, because you did forget some. That's the number, and once it's set you never do the math again.

The Buffer amount is whatever you can spare, even if it's small at first. The goal is a buffer that could cover one month of bills. The starting point is one week's worth. Once the buffer reaches its target, the transfer can stop or shrink, but leave it running if you can. A buffer that refills itself is a buffer you never have to think about.

Whatever's left lands in Spending. That's yours. Spend it however you like, with no accounting to anyone, until it's gone or the next payday arrives.

If your income is irregular, there's an extra step in front of this, where revenue lands in a holding account and you pay yourself a fixed salary from it. That's covered separately in Irregular income with ADHD. Once the salary lands, the routing works the same way.

One card, not seven

Multiple cards multiply the leaks. Every extra card is another statement you won't open, another due date to lose track of, another saved number on a shopping site at 11pm. It also breaks the one-number system, because the Spending balance stops being the truth if part of your spending is happening somewhere else.

So pick one. The debit card on the Spending account is the simplest choice, because the balance is the number and there's no bill later. If you prefer a credit card for the rewards or the protection, that's workable, but only if it's paid in full automatically from Spending every month and you treat its balance as already spent. Be honest about which of those two you'll maintain. For a lot of people with this brain, the debit card wins, because "the number on the card is the number" needs no second step.

The other cards don't need to be cancelled. Put them in a drawer. Delete their numbers from every browser and shopping app where they're saved. Keep the accounts open if closing would hurt your credit, but make them physically and digitally hard to reach. The goal is that when your hand reaches for a card, there's only one to find.

One number

With the accounts set up and the routing running, there's one figure you need to look at between paydays: the Spending balance.

Make it easy to see. A widget on the phone's home screen. The card's app with notifications on. A sticky note on the fridge, updated on Sunday. The point is that checking it should take two seconds and no login. Wherever a budget would've asked you to open an app and scan twelve categories, you glance at one number and know the answer.

Everything else stays out of sight. Don't check Bills between paydays. Don't reconcile. Don't look at the buffer. That sounds irresponsible to someone who was raised on "watch your money closely," but this brain doesn't do closely, it does binges of attention followed by months of avoidance. The system is designed so that not looking is safe. That's the feature. Bills pays itself. Buffer catches the mistakes. You look at one number and go about your life.

The Ten-Minute Money Date

The system doesn't need daily attention, but it does benefit from a small weekly look. This is the Ten-Minute Money Date, and it's built to be done on autopilot.

Pick a day. Sunday works for a lot of people. Set a timer for ten minutes. Then run the same short checklist every time.

• Open the mail. All of it, using the Envelope Protocol: open, don't act; three piles; recycle the pile that needs nothing.
• Look at three things. The Spending balance. Anything in Bills that looks wrong, like a charge you don't recognize or an autopay that didn't go through. The calendar for next week, for anything unusual, like an annual charge or a trip.
• Close the laptop. When the timer goes, you're done, even if you feel like you could keep going. Especially then.

That's the whole date. Three things to look at and, in the words of the companion card that ships with the guide, twelve things to ignore. Body doubling is welcome. So is skipping it. If you miss a week, nothing breaks, because the system was never depending on Sunday. You come back the following week and the checklist is the same.

What happens when you fall off

You will fall off. Everyone with this brain does, and the system is built for it. A hard month at work, an illness, a stretch where you don't look at money for three weeks. The difference from every other system you've tried is what happens next.

Bills kept paying itself. The buffer absorbed anything odd. The routing ran on every payday whether you were watching or not. When you come back, the restart takes about fifteen minutes: check that the autopays are still current, look at the buffer, run one money date. The guide has you write this down on a single card while you're doing well, with the accounts, the amounts, and the three restart steps, so that future you doesn't have to reconstruct anything from memory.

The goal was never a system you could maintain. The goal is a system you can restart.

Setting it up this weekend

Here's the afternoon, in order. Open three accounts at your current bank, or a new one with instant transfers. List every recurring payment and move it to autopay from Bills. Calculate the Bills amount and set the transfer. Set a Buffer transfer, any size. Move your day-to-day spending onto one card attached to Spending and put the others in a drawer. Put the Spending balance somewhere you'll see it. Pick a day for the ten-minute date.

That's the system. Three accounts, no categories, and a handful of decisions made once. The full version, with the routing worksheets, the buffer sizing, the irregular-income variation, and the one-page map you restart from, is in The ADHD Money Guide. But everything above is enough to start, and starting is the part that was hard.
