Estimate the maximum SBA 7(a) loan your cash flow supports from target DSCR, interest rate, and term — with the $5M program cap applied automatically.
Cash flow & terms
Estimated maximum loan
An estimate based on cash flow and the 7(a) cap — not collateral, eligibility, or equity injection. LendPipe checks all of those at intake.
See SBA automationHow cash-flow sizing works
Loan sizing starts from how much debt service the borrower's cash flow can cover at your target coverage ratio:
Max Debt Service = Annual Cash Flow ÷ Target DSCR
That maximum annual payment is then converted into a loan principal using the interest rate and amortization term, and capped at the SBA 7(a) program limit of $5 million.
Worked example
A business generates $600,000 in cash flow available for debt service. At a 1.15x target DSCR, it can support about $522,000 of annual debt service — roughly $43,500 per month. At an 11.5% rate over 10 years, that payment supports a loan of approximately $3.0 million, well under the $5M cap, so cash flow is the binding constraint.
What this estimate does not include
- Collateral coverage and the required equity injection.
- Use-of-proceeds eligibility and business size standards.
- SBA guaranty fees and the lender's own credit overlays.
Frequently asked questions
How is the maximum SBA loan amount calculated?
Cash-flow sizing works backward from the borrower's available cash flow. First, divide annual cash flow by the target DSCR to find the maximum annual debt service the borrower can support. Convert that to a monthly payment, then calculate the loan principal whose payment — at the given interest rate and amortization term — equals that figure. The result is the largest loan the cash flow supports, which is then capped at the SBA 7(a) program maximum.
What is the maximum SBA 7(a) loan amount?
The SBA 7(a) program caps loans at $5 million. Many borrowers are constrained by cash flow well before reaching that ceiling — this calculator shows both the cash-flow-supported amount and the $5M cap so you can see which one is binding. The SBA 504 program has a separate structure and limits and is not modeled here.
What terms do SBA 7(a) loans use?
Maximum maturities depend on use of proceeds: up to 25 years for real estate, up to 10 years for equipment and most business acquisitions, and up to 10 years (often 7) for working capital. Most 7(a) loans carry variable rates tied to the prime rate plus a spread, subject to SBA maximum rate caps. Use the actual proposed rate and term for an accurate estimate.
Is this a loan pre-approval?
No. This is a cash-flow-based sizing estimate only. Actual SBA loan amounts also depend on collateral coverage, the required equity injection, use-of-proceeds eligibility, credit history, business size standards, and the lender's own credit policy. Treat the result as a starting point for structuring, not a commitment or pre-approval.
Underwrite SBA loans without the busywork
LendPipe classifies SBA forms, spreads every entity and guarantor, and builds global cash flow automatically — so eligibility and sizing are clear at intake, not three weeks in.
