How Much Money Do You Need to Buy a Business?

The Short Answer

With SBA financing, buyers typically need a down payment of around 10% of the purchase price, plus closing costs, working capital, and a personal cash reserve. On a $1,000,000 business, that often means roughly $100,000 down and additional cash on hand — not the full million. The whole point of acquisition financing is that the business's own cash flow repays most of the price over time.

The mistake buyers make is budgeting only for the down payment. The cash you need to close and survive the first months is what really matters, and it is more than the down payment alone.

The Down Payment

For an SBA 7(a) acquisition loan, the SBA generally requires a minimum equity injection of about 10% of the total project cost. That equity can sometimes be split — for example, part from the buyer and part from a seller note placed on full standby that counts toward the requirement. Conventional (non-SBA) acquisition loans usually require more down, often 20% or higher.

On larger, lower-middle-market deals, the structure changes — more equity, sometimes private capital or a search-fund structure — but for the typical small-business acquisition, the roughly 10% SBA down payment is the anchor number buyers plan around.

Beyond the Down Payment: What Else You Need

Closing on a business and running it takes more than the down payment. Budget for:

• Closing costs — SBA guarantee fee, lender fees, escrow, and legal; these can add several percent of the loan amount
• Working capital — cash to fund payroll, inventory, and receivables while the business keeps running through the transition
• A personal reserve — living expenses and a cushion for the first slow month, so you are not forced into bad decisions
• Any required improvements — equipment, a franchise-mandated remodel, or deferred maintenance you plan to address

Running out of cash immediately after closing is one of the most common and avoidable buyer failures. Lenders often build a working-capital line into the financing, but you should still bring your own cushion.

How to Reduce the Cash You Need

Several levers lower a buyer's out-of-pocket cash:

• Seller financing — a seller note, especially on standby, can count toward equity and reduce what you must put in
• SBA structuring — financing working capital and closing costs into the loan rather than paying cash
• Choosing the right deal — a business with strong, clean cash flow is easier to finance with less friction
• Partners or investors — sharing the equity injection, common in search-fund and ETA structures

The art is doing this without over-leveraging: borrow too aggressively and the debt service can starve the business of the cash it needs to operate and grow.

What Lenders Want to See

Beyond cash, SBA lenders underwrite you and the business. They look at your credit, relevant management experience, and the size of your injection, and at whether the business's historical cash flow comfortably covers the new debt payments (the debt-service coverage ratio). A business with clean books and durable earnings is far easier to finance — which is why how the business is valued and how solid its earnings are directly affects your ability to buy it.
