Four-Square / 4-Square Method
A worksheet that confuses you about price, trade, down payment, and monthly. Refuse it.
The four-square is a piece of paper divided into quadrants — vehicle price, trade-in, down payment, and monthly payment. Salespeople use it to manipulate four numbers simultaneously, making it hard to track which one is actually moving. The defense: insist on negotiating ONE number at a time, starting with out-the-door price. Read more in our four-square deep dive.
01A worked example: how the monthly payment hides the price
Say you are financing $30,000 at 6 percent APR for 60 months. That is about $580 a month, or about $34,800 in total payments. You tell the salesperson the payment is too high.
The next four-square comes back at about $530 a month. It looks like a $50 win. But the dealer stretched the term to 72 months and added $2,000 to the amount financed, maybe a package, maybe a smaller trade value. Total payments are now about $38,180. You pay roughly $3,380 more for a lower monthly number. That is the whole trick: move the term, the trade, or the down payment, and the payment can drop while the deal gets worse.
The fix is to look at the total, not the payment. Ask the dealer to show the selling price, the term, the APR, and the total of payments on every version they send you. If any of those four changed, the deal changed, no matter what the monthly number says.
02How to spot a four-square without the paper
The grid is not always drawn on a sheet. The same move shows up in conversation and email: what monthly payment are you looking for, how much can you put down, we can do more on your trade if. Any question that bundles price, trade, down payment, and payment into one answer is the four-square.
Another sign is a quote that shows a payment but no itemized total. If you cannot see the selling price, every fee, and the out-the-door price on one page, the numbers are still being moved around behind the payment.
03What to say instead
Separate the four numbers and settle them in order. First, the itemized OTD price, in writing. Second, your trade-in value, as its own written number. Third, financing, compared against a pre-approval from your bank or credit union. Your down payment is your choice and never needs to be negotiated.
If the salesperson asks for a target payment, reply: I am not shopping by payment. Please send the out-the-door price for this car. The longer version of this defense is in the four-square method.
04Questions buyers ask
Is the four-square illegal?
No. It is a sales worksheet, not a fraud. What matters is the contract you sign. The Truth in Lending Act requires the lender to disclose the APR, amount financed, and total of payments, so read those numbers on the contract, not just the monthly figure.
Can I just give a target payment to speed things up?
It speeds things up for the dealer. A target payment lets them hit your number with a longer term or a higher rate while the price stays high. Give an OTD target instead, and work out the payment yourself once the price is settled.
