Most borrowers negotiate a loan by arguing about the interest rate. Lenders find this amusing, because the rate is only one dial on a panel of thirty. The real economics of a loan live in its structure — the tranches, tenor, amortization, covenants, and security that determine how the debt behaves when your business has a bad year. Here is how lenders actually build one.
Start with the purpose, not the amount
Every loan structure begins with a question: what is this money for, and what cash flow pays it back? A loan funding a warehouse gets repaid from the trading margins the warehouse enables. A loan funding equipment gets repaid over the equipment's working life. A bridge loan gets repaid from a specific future event — a receivables collection, an asset sale, a refinancing.
This matching principle — funding tenor against the life of what you are buying — is the first thing a credit committee checks. Asking for a one-year loan to fund a ten-year asset signals that you either misunderstand your own balance sheet or intend to roll the debt forever. Neither reads well.
The building blocks
A term sheet compresses a dozen structural decisions into a few pages. The ones that matter most:
- Tranches. Facilities are often split — a term loan for the fixed investment, a revolving line for working capital swings. Each tranche has its own rate, tenor, and drawdown rules.
- Amortization. Bullet repayment (all principal at maturity), straight-line, or sculpted to match expected cash flows. Amortization is where affordability is really determined; two loans at the same rate can have wildly different cash demands.
- Security. What the lender can claim if things go wrong — specific assets, receivables, shares in the operating company, or guarantees from the parent.
- Covenants. The tripwires. Financial covenants (maximum leverage, minimum debt service cover) and behavioral covenants (no dividends above a threshold, no new debt without consent).
- Pricing grid. Increasingly, the margin ratchets up or down with performance — a reward for deleveraging, a penalty for drifting.
Why covenants deserve your attention
Borrowers skim covenants; lenders draft them carefully. A covenant is a pre-agreed moment when the lender can demand a conversation — or worse. A leverage covenant set at 3.0x EBITDA when your base case runs at 2.2x leaves you one bad quarter away from a technical default, even if you never miss a payment.
The negotiation that matters is headroom: covenants should sit 25 to 35 percent above your realistic worst case, tested against your own downside model, not the lender's template. Ask for covenant holidays around known seasonal troughs, equity cure rights that let you inject cash to fix a breach, and definitions of EBITDA that match how your accounts actually work. These details decide whether a covenant is an early-warning system or a trap.
How the lender prices risk
Behind the term sheet sits a simple equation: the lender needs the loan's expected return — after the probability-weighted cost of default — to clear their hurdle rate. Everything in the structure either reduces the probability of default (covenants, amortization, conservative leverage) or reduces the loss given default (security, guarantees). The more of the first two you can credibly offer, the more room opens on pricing and quantum.
This is why preparation moves pricing. A borrower who arrives with three years of clean audited accounts, a credible cash flow model, and a clear use of funds has already answered half the credit committee's questions. Uncertainty is the most expensive line item in any loan.
A practical checklist before you sign
- Model the amortization schedule against your pessimistic cash flow, not your plan.
- Read every covenant definition and build a quarterly compliance forecast for the full tenor.
- Map the security package: know exactly which assets and entities are encumbered, and what that means for future borrowing.
- Check prepayment terms — flexibility to refinance cheaply is worth real money if rates fall or your credit improves.
- Understand the events of default beyond non-payment: cross-defaults, audit qualifications, ownership changes.
A well-structured loan is quiet. It amortizes out of ordinary cash flow, its covenants never trip, and nobody thinks about it again. That silence is engineered at the term sheet stage — which is exactly where an experienced adviser earns their fee.
