What is a good DSCR for a small business loan?

Many lenders look for roughly 1.25x or higher, meaning $1.25 of cash flow for every $1 of debt payments. Requirements vary by lender and product, and faster products often weigh recent revenue more than a formal ratio.

How do I calculate DSCR?

Divide the cash your business has available for debt payments (revenue minus operating expenses, before loan payments) by your total debt payments for the same period, including the new loan.

Is it better to take a longer term to lower the payment?

A longer term lowers the monthly payment and improves coverage, but increases the total interest you pay. Choose the shortest term whose payment your cash flow carries comfortably in a slow month.

How much can your business afford to borrow?

How much a lender will approve and how much your business can comfortably carry are two different numbers. Work out the second one yourself, before anyone makes you an offer.

Key takeaways

Affordability is about the payment against your cash flow, not about the loan amount.
The debt service coverage ratio (DSCR) is cash available for debt divided by total debt payments.
Many lenders look for roughly 1.25x or higher: $1.25 of cash flow for every $1 of payments.
A longer term lowers the payment and raises the total cost. Use it deliberately.

The one ratio that matters

Lenders size loans with the debt service coverage ratio, or DSCR:

DSCR = cash available for debt payments ÷ total debt payments

Cash available is what is left from revenue after operating expenses, before any loan payments. Total debt payments include what you already pay plus the new payment. A ratio of 1.00x means every dollar of spare cash goes to lenders. Many lenders look for roughly 1.25x or higher, which leaves a cushion for a slow month.

A worked example

A business averages $60,000 a month in revenue and $52,000 in operating expenses, leaving $8,000. It already pays $1,500 a month on an equipment loan and wants to borrow $100,000 over 48 months at 15% APR.

New payment: about $2,783 a month
Total debt payments: $4,283 a month
DSCR: $8,000 ÷ $4,283 = 1.87x
Cash left after all payments: $3,717 a month

That is comfortable. Double the request to $200,000 and the new payment becomes $5,566, the ratio drops to 1.13x, and one soft month would put the business behind.

Payment affordability check

See whether your monthly cash flow comfortably covers a new payment, using the same coverage ratio lenders use.

Average monthly revenue$ Monthly operating expenses (before loan payments)$ Existing monthly loan payments$ New amount you want to borrow$ Estimated APR% Term in months

Coverage ratio (DSCR)1.87x

What that means: Comfortable. You are at or above the 1.25x many lenders look for.
New monthly payment: $2,783
Cash left after all payments: $3,717
Largest new payment that keeps you at 1.25x: $4,900

Use real averages from your last 6 to 12 months of bank statements, not your best month. Estimates for learning only. Not an offer, a quote, or financial advice.

Four ways to make the numbers work

Borrow less. Fund the essential part of the project now and the rest from cash flow later.
Lengthen the term. $100,000 at 15% APR costs about $3,467 a month over 36 months and $2,379 over 60. The longer term adds about $17,944 in total interest, so use it when cash flow needs the room.
Clear a small existing balance first. Removing an old payment raises the ratio as surely as adding income.
Lower the rate. Stronger credit, collateral, or a slower product such as an SBA loan can reduce the payment on the same amount.

Run the ratio on an average month and again on your slowest month of the last year. If the slow month falls below 1.00x, plan for it before you sign: a smaller amount, a longer term, or a line of credit as a cushion. WithFunded guidance.
