Can the business service it?

The first question is not the rate; it is whether the cash flow supports the payment. Lenders test this with a debt service coverage ratio — operating income divided by total debt payments — and generally want 1.25 or better. Run the same test yourself before applying, using conservative revenue assumptions rather than the forecast you would like to be true.

Revenue required, not profit required

A $2,500 monthly payment at a 12% net margin requires roughly $250,000 of additional annual revenue to service comfortably from new business. Framing the loan that way — in revenue terms — makes the commitment concrete in a way that a payment figure does not.

Types of business finance, roughly by cost

  1. SBA loans — the lowest rates for qualifying businesses, but paperwork-heavy and slow.
  2. Bank term loans — competitive for established businesses with collateral and history.
  3. Equipment financing — secured by the asset, so rates are usually reasonable.
  4. Business lines of credit — interest only on what you draw; ideal for working capital swings.
  5. Invoice factoring — expensive but fast, and useful when the problem is timing rather than solvency.
  6. Merchant cash advances — the most expensive by a wide margin; treat as a last resort.

Match the term to the purpose

Finance long-lived assets over long terms and short-term needs over short terms. Funding inventory with a seven-year loan means paying interest for years after the stock has been sold. Funding a building with a two-year loan creates a repayment cliff. Mismatch is one of the more common causes of avoidable business distress.

The fine print that matters

Check for prepayment penalties, personal guarantee scope, financial covenants (minimum ratios that can trigger default), blanket liens on business assets, and whether the rate is fixed or floating. On a floating rate, model the payment two or three points higher and confirm the business still works.

Frequently asked questions

What rate should I expect?

SBA 7(a) loans are capped at a spread over prime and are usually the cheapest option for qualifying businesses. Conventional bank term loans price on credit and time in business. Online and merchant cash advance products are far more expensive — sometimes 40%+ effective.

Beware of factor rates

Merchant cash advances quote a 'factor rate' like 1.35, meaning you repay $1.35 per dollar. Over a short repayment period that can equate to an APR above 60%. Always convert to an APR before comparing.

Will I need a personal guarantee?

Almost always for small business lending, including SBA loans. It means personal assets are at risk if the business cannot repay — a point worth weighing carefully.
