Personal Guarantee
A personal guarantee is a legal commitment by a business owner or executive to repay a company’s debt from their own assets if the business fails to pay. It is common on small business loans, leases, and business credit cards, and it lets a lender or card issuer look past the company to the individual who signed. The guarantee can cover the full balance or a set amount, and it usually survives even if the business closes.

Why personal guarantees matter
Forming a company is meant to separate business debt from personal finances. A personal guarantee reverses that for the debt it covers.
Lenders ask for guarantees when they are unsure the business alone can repay, which is most of the time for younger or smaller companies. The owner’s personal credit history becomes part of the underwriting, and the owner’s savings, home, or other assets can be pursued if the business defaults. The risk is easy to overlook when the balance is small and hard to ignore when it is not.
For agencies, the exposure scales with client spend. An owner who guarantees a card carrying $300,000 a month of client ad spend is personally backing money that belongs to clients, and personally exposed if one of those clients pays late or not at all.
How businesses approach personal guarantees
- Reading the agreement: checking whether the guarantee is unlimited, capped, or limited to a specific facility.
- Negotiating limits: asking for a cap or for the guarantee to fall away after a period of on-time payment.
- Choosing underwriting: using programs that assess the business’s cash flow and managed spend rather than the owner’s personal credit.
- Separating obligations: keeping client-funded spend off facilities the owner has guaranteed.
Business examples
A founder who signed a guarantee on a card with a $50,000 limit that later grew to $500,000 as client media moved onto it. An agency owner refinancing onto a facility with no guarantee before taking on a large new retainer. A business partner discovering at a sale that a lease guarantee still named them personally.
For the agency-specific view, see business cards with no personal guarantee for agencies.
Frequently asked questions
No, but many do, particularly for small and younger businesses. Cards that skip the guarantee usually underwrite on the business itself, such as revenue, cash flow, or managed spend, instead of the owner’s personal credit.
The guarantee normally stays in force. If the company closes with an unpaid balance, the lender or issuer can seek repayment from the person who signed, up to the amount the guarantee covers.
Sometimes. Some lenders agree to release or cap a guarantee after a record of on-time payments or once the business meets financial thresholds. Otherwise the usual route is to move the balance to a facility that does not require one.
