1.25. Before a manufacturer talks seriously about a machine, an expansion, or a credit line, a commercial lender will run one figure through the file: debt service coverage, with a target of 1.25x or better. That single ratio decides more applications than any other number in the stack — but it is only one of five worth understanding before you apply.
Manufacturers finance differently from most industries. The asset base is heavy, the working-capital cycle is long, and one machine decision can change the company's entire output. Below are the five numbers lenders read first, what each one signals about your business, and then a worked example showing how a $250,000 equipment purchase actually gets underwritten — arithmetic included.
The five numbers interact, which is the part most applications get wrong. A stronger down payment improves coverage; a shorter cash cycle reduces how much working capital you have to finance; a longer term lowers the monthly payment but raises total cost. Read them as a system and the structure decisions become far more obvious.
| The number | What it measures | What lenders commonly target |
|---|---|---|
| 1.25x | Cash flow versus total annual debt service | 1.25x or better |
| 80–100% | Share of new equipment cost financed | Equipment loan or lease |
| 5–10 years | Loan term versus equipment useful life | Matched to the asset |
| 60–120 days | Cash conversion cycle | Depends on the sector |
| 10% / 90% | Equity injection (SBA 7(a)) / financing share (SBA 504) | Program parameters |
1.25x: Debt Service Coverage
Debt service coverage — DSCR to everyone who works with it daily — is net operating income divided by total annual debt service, including the proposed new loan. A shop generating $400,000 of operating income with $250,000 of annual debt payments after the new machine runs about 1.6x. Lenders commonly want at least 1.25x; some programs flex to 1.20x, and anything under that invites either a larger down payment, more owner injection, or a smaller ask.
The part first-time borrowers miss: existing obligations stay in the denominator. Every open equipment loan, floor-plan line, and vehicle payment counts against you, even ones you plan to pay off after closing. If you can retire small loans before applying, the same project suddenly qualifies without changing a line of the purchase itself. Underwriters are not looking for a reason to say no — they are measuring how much cushion exists when a slow quarter arrives, because in manufacturing, one will.
For owners new to the ratio, the mechanics are simpler than the vocabulary. Start with pre-tax profit, add back interest expense, depreciation, and one-time items, and subtract an owner's salary if the business currently pays above-market wages. Add the proposed payment to existing debt, divide, and you have the underwriter's arithmetic. Running it yourself first is worth the hour it takes — a file that arrives with the borrower's math already done gets faster, more confident reads.
80–100%: Equipment Advance Rates
New equipment purchased from a dealer or manufacturer is commonly financed at 80–100% of invoice for established operations with clean credit — meaning a well-prepared buyer can put down 10–20% or occasionally nothing beyond costs. Used equipment leans harder on appraisals, and advance rates commonly land around 70–80% of appraised value, because resale markets for used machinery are thinner and the lender wants a cushion.
Freight, rigging, and installation are sometimes financeable or rolled into the note; ask before you sign the purchase order, because those soft costs are easy to overlook until delivery week. This is bread-and-butter equipment financing, and it is usually the fastest capital a manufacturer can access — decisions in days to a couple of weeks for a clean file.
Two practical notes. The advance runs against invoice or appraisal, not against an asking price — keep your purchase documentation clean and at arm's length. And weaker credit or a young business shifts the math: expect 10–25% down in those cases, and treat any 100% financing headline as something that has to be offset elsewhere in the file.
5–10 Years: Terms Matched to Useful Life
Terms on manufacturing equipment commonly run three to ten years, matched to the machine's working life: five to seven years for CNC machines and material-handling equipment, seven to ten for heavy presses and long-life fixtures. The matching matters in both directions. Stretch a five-year asset over ten years and you are paying interest on a machine that is scrap metal while the note still has years to run. Cram it into three years and the monthly payment crushes the very cash flow the machine is supposed to generate.
One nuance worth a conversation with your CPA: loans and leases differ in ownership and tax treatment, and the right choice depends on how the asset depreciates and how the business files. Lenders underwrite the payment; your accountant decides how to carry it. One contract detail to catch: where the residual sits. A $1 end-of-lease buyout and a fair-market-value clause are different bets on how long you keep the machine and what keeping it finally costs.
60–120 Days: The Cash Conversion Cycle
Add your inventory days and receivable days, then subtract the days your suppliers give you. Forty-five days of inventory plus 45 days of receivables minus 30 days of payables equals a 60-day cash conversion cycle — and on $4 million of revenue, roughly $660,000 is tied up in that cycle at any given moment. Lenders read the trend the way a doctor reads blood pressure: a cycle creeping from 60 days to 90 tells them growth is eating cash faster than the business generates it.
Two tools address the gap. A business line of credit covers the revolving rhythm — material purchases, payroll between shipments, the gap between invoicing and payment. A working capital loan fits structural gaps that will not resolve in a quarter, like a new product line or a major contract with 90-day pays. The worst move is using short-term money to fund a problem that will take a year to fix. Sizing check: a shop running a 60-day cycle on $4 million of revenue commonly needs $330,000 to $500,000 of availability to keep material moving without borrowing ahead of itself. Ask for a line that reflects the cycle you can document, not the one you wish you had. For contract-heavy work, purchase-order financing and receivables advances can bridge specific gaps the line does not cover — the most expensive money in the stack, best used against a signed order with a margin you can defend.
10% and 90%: Equity Injection and the SBA 504
On an SBA 7(a) loan — the program runs to $5 million — manufacturers commonly inject about 10% of the project cost, with the SBA guaranteeing a majority of the balance. That injection can include the down payment on equipment, closing costs, and sometimes seller-carried notes in acquisition scenarios, depending on structure. For owner-occupied buildings and long-life equipment, the SBA 504 structure borrows differently: commonly 50% bank loan, 40% CDC loan capped at $5.5 million, and 10% borrower equity — about 90% financing of the project, priced off long-term Treasury benchmarks because the terms stretch 20 years or more. Read how the programs compare on our SBA loans page before assuming which side of the line your project falls on. One timing note: because 504 debentures are funded on a periodic cycle tied to longer benchmarks, the program is built for patience rather than speed — plan a longer runway than a 7(a) would need.
A Worked Example: The $250,000 Machine
A machine shop doing $3.5 million in revenue buys a $250,000 CNC. The lender advances 80% against the invoice — $200,000 financed, $50,000 down, plus a few thousand for freight and installation the buyer budgets separately.
The payment: at a 10% annual rate over 84 months — market pricing for established shops commonly falls in the high single digits to low double digits, and the example simply uses 10% to keep the arithmetic round — the monthly payment runs about $3,320. Annual debt service lands near $39,850.
The coverage test: at 1.25x, the machine needs to generate at least $49,800 a year — roughly $4,150 a month — in added cash flow to pass comfortably, on top of whatever the shop already carries.
The realistic case: the machine cuts cycle times and scrap on existing work and opens up new jobs worth an estimated $8,000 a month in additional gross profit. That is $96,000 a year, which arrives at $96,000 divided by $39,850 — a DSCR of about 2.4x. The file is comfortably bankable.
The sensitivity case: if the same machine only added $2,000 a month — $24,000 a year — coverage drops to about 0.6x, and the answer becomes more money down, a longer term, or a different machine. That sensitivity test, not the purchase price, is what underwriting is really about: not whether you can buy the machine, but whether the machine can service its own note.
An alternative worth pricing: dropping the advance to 70% — $175,000 financed, $75,000 down — cuts the payment to roughly $2,900 a month. Coverage on that weak $24,000 case still lands near 0.7x, which tells you the real fix is a machine with more impact or a structure with a lower payment, not more cash down. Running these three versions of the file before an application is exactly what underwriting would do to it.
One more line in the file matters after closing. The $50,000 down payment plus install costs can drain the cash you need to run the new work — material, tooling, and labor for the jobs the machine is supposed to win. Keep a working-capital buffer intact, even if it means financing slightly less machine, and the first year goes according to plan.
And keep the paperwork that makes all of this verifiable: two years of returns, year-to-date statements, the vendor quote and spec sheet, and a one-page summary of how new work converts to cash. Underwriters can argue with projections; they rarely argue with a clean quote and a purchase order.
The arithmetic above is simple on purpose, because the deals that get declined usually fail one of these five numbers, not all five.
