How much deposit do you need to buy a business?

There is no fixed deposit to buy a business in the UK: the amount you need to put in depends on the price, how much debt the business's profits can support, the assets available as security, how much the seller will defer and your own track record. Lenders rarely fund the whole price, so buyers usually combine their own contribution with senior debt, asset-backed lending and seller finance. This guide is for individuals, management teams and existing companies planning a purchase and wondering how much cash they need. Smart Funding Solutions is a broker, not a lender. We arrange acquisition finance from around £10,000 to £500,000+, with larger facilities available in suitable cases, and the size of your contribution is one of the first things we discuss.

01Why there is no set deposit

There is no set deposit because business acquisition lending is sized on the target's cash flow and security, not on a fixed loan-to-value ratio as with a residential mortgage. Two businesses with the same price can need very different contributions. One with strong, recurring profits, a debtor book and owned equipment may support a large share of the price in borrowing. Another with lumpy profits, few assets and heavy dependence on its owner may support very little, leaving the buyer and the seller to fund most of it.

Lenders also look at the buyer's contribution as a sign of commitment. Someone who has invested money that would hurt to lose has every reason to make the business work, and their money absorbs the first losses if trading dips. So even where the numbers would support more debt, lenders usually want to see a meaningful contribution from the buyer.

02The factors that set your contribution

Your contribution is effectively whatever is left after the other funding layers have been sized, so the factors that limit those layers set the figure.

• Price against maintainable profit. The higher the price relative to adjusted earnings, the less of it debt can cover. Our guide to how to value a business explains how maintainable profit is worked out.
• Debt affordability. Lenders test whether repayments can be met from cash flow after the new owner's salary, tax and capital spending, with headroom for a weaker year.
• Security. Debtors, stock, equipment and property can support asset-backed lending on top of, or instead of, a cash flow loan.
• Seller cooperation. The more the seller is willing to defer, the less you need at completion.
• Your experience. A buyer with a track record in the sector, or an existing business making a bolt-on purchase, is generally seen as lower risk than a first-time buyer from outside the industry.
• Sector and business quality. Recurring income, a broad customer base and a management team that stays all improve the funding case.
• Diligence findings. Issues uncovered in due diligence when buying a business can reduce what lenders offer late in the process, so leave some margin.

03How the funding stack fits together

Most acquisitions are funded by a stack of layers, with the buyer's contribution at the bottom absorbing first loss and senior debt ranking first for repayment. The main layers are described below.

Senior debt

A term loan from a bank or specialist lender is the backbone of most deals. It is sized on maintainable cash flow and is usually secured by a debenture over the business, often with personal guarantees from the buyers. Where security is limited, some lenders can use the British Business Bank's Growth Guarantee Scheme, which gives the lender a partial government guarantee; the borrower remains fully liable. Our Growth Guarantee Scheme overview explains how it works in general terms, and details are on the British Business Bank website.

Asset-backed lending

Assets in the business being acquired can often be borrowed against at completion. Invoice finance on the acquired debtor book can release a large part of its value on day one and then keep funding working capital as invoices are raised. Plant, vehicles and machinery the target owns outright can sometimes be refinanced through asset refinancing. Property can support a commercial mortgage. Each of these reduces the amount the buyer must find in cash.

Vendor finance and deferred consideration

Deferring part of the price, as fixed instalments or an earn-out, is one of the most effective ways to reduce the contribution needed at completion. Lenders usually require deferred amounts to rank behind their debt and to be paid only when the business can afford them. Our guide to vendor finance and deferred consideration covers how these arrangements are structured and documented.

Goodwill lending

In professional practices and similar businesses where the main asset is the client bank, specialist lenders will fund goodwill against recurring fees and the practice's track record. Goodwill finance can cover a significant part of a practice purchase, and our page on practice acquisition finance explains how lenders view client banks. In one completed case, we arranged a £137,500 facility for an established accountancy firm buying another practice, where much of the value lay in the client bank, recurring fees and goodwill; see the accountancy practice acquisition case study.

Your contribution is effectively whatever is left after the other funding layers have been sized, so the factors that limit those layers set the figure.

04An illustrative funding stack

Illustration only. The figures are hypothetical and rounded, and no lender is committed to any structure like this. A buyer agrees to purchase a profitable services business for £1,000,000. The business has a debtor book and some owned equipment.

In this illustration the buyer's cash is a minority of the price, but the business must now service the term loan, the deferred payments and the invoice finance costs from its cash flow. A lender would test whether all of that is affordable in a flat year. If it is not, the answer is usually a lower price, more deferral or more equity rather than more debt. Different businesses produce very different stacks: one with no debtors or assets might need a much larger contribution or much more seller support.

05What lenders look for in your contribution

Lenders look at where your contribution comes from as closely as at how large it is. Expect them to ask for:

• Source of funds. Bank statements and documents showing how the money was built up or released, such as savings, a property sale or remortgage, an inheritance or a pension lump sum. Anti-money-laundering checks require this.
• Whether it is borrowed. Money borrowed personally, for example by remortgaging your home or taking a personal loan, can be used, but lenders will count the repayments when assessing your personal position and the salary you need from the business.
• Whether it is at risk. Lenders want the contribution to be genuinely invested in the deal, usually as share capital or a subordinated loan to the buying company, not repayable ahead of the bank.
• Gifts and investors. Family gifts generally need a letter confirming they are not repayable. Money from investors may bring shareholder rights and expectations that the lender will want to understand.
• Personal resilience. A statement of personal assets and liabilities, particularly if you are giving a personal guarantee.

06Where buyers find their contribution

Buyers usually fund their contribution from a mix of personal and business resources. Common sources include personal savings, equity released from a home or investment property, proceeds from selling a previous business or shares, a pension lump sum taken in line with the rules (take regulated financial advice first), family support, or cash and borrowing capacity in an existing company that is making the purchase. Partners or co-investors can share the contribution, and in management deals each manager typically invests according to their means. Some buyers also use the target's own surplus cash at completion, where the price and structure allow it.

07Contribution by type of deal

The contribution lenders expect varies with the type of transaction, because each carries a different level of risk.

08Reducing the contribution you need

You can reduce the cash needed at completion by negotiating structure as well as price. Ask the seller to defer more of the price or accept an earn-out, use the target's debtors and assets to support asset-backed lending, buy assets rather than shares where that excludes items you do not need, or bring in a partner. Be careful not to replace your own money entirely with extra debt: every layer competes for the same cash flow, and an over-geared business has little room for the dip in trading that often follows a change of owner. Our guide on whether to take a loan to buy a business includes a simple stress test.
