SBA Loan Calculator

Estimate monthly payments, the upfront guaranty fee, and total cost for an SBA 7(a) loan, or model the 50/40/10 structure and combined payment of an SBA 504 loan. Switch between the two programs and adjust your rate, term, and amount to see what a deal actually costs.

In FY2025 the SBA backed roughly 77,600 7(a) loans totaling about $37 billion, according to the U.S. Small Business Administration. All figures follow the current rulebook, SOP 50 10 8.

How SBA 7(a) Payments Are Calculated

An SBA 7(a) monthly payment is a standard amortizing payment: your loan amount, interest rate, and term determine a fixed monthly figure that pays down principal and interest over the life of the loan. Terms typically run up to 10 years for working capital and equipment and up to 25 years for real estate.

Most 7(a) loans carry a variable rate tied to the prime rate plus a lender spread, and the SBA caps how large that spread can be by loan size. The maximum spreads below come from the SBA 7(a) program page.

Loan SizeMaximum Spread Over Base Rate
$50,000 or lessBase rate + 6.5%
$50,001 – $250,000Base rate + 6.0%
$250,001 – $350,000Base rate + 4.5%
Over $350,000Base rate + 3.0%

The maximum SBA 7(a) loan is $5 million, with the SBA guarantee capped at $3.75 million (85% for loans of $150,000 or less, 75% above that).

SBA Guaranty Fees in 2026

Every 7(a) loan carries a one-time upfront guaranty fee. For FY2026 (Oct 1, 2025–Sep 30, 2026), the fee returned to the statutory schedule — the small-loan fee waivers of prior years ended, per SBA Information Notice 5000-872051 and SOP 50 10 8. Your fee bracket is set by the total loan amount, but the percentage is charged on the guaranteed portion of the loan, not the full loan amount — and the fee is commonly financed into the loan.

Total Loan AmountUpfront Fee
$150,000 or less2.0% of the guaranteed portion
$150,001 – $700,0003.0% of the guaranteed portion
Above $700,0003.5% of the guaranteed portion up to $1M, plus 3.75% on the guaranteed portion above $1M
Qualifying small manufacturers (NAICS 31–33), loans ≤ $950,0000%

The small-loan fee waivers have ended

In prior years the SBA waived upfront fees on many smaller loans. For FY2026 those waivers are gone and the statutory schedule above applies. Lenders also pay the SBA a 0.55% annual service fee on the outstanding balance — that is a lender cost and is not billed to you directly.

How the SBA 504 Structure Works

The SBA 504 program finances owner-occupied commercial real estate and heavy equipment through a three-part structure. A conventional bank provides a first-lien loan for about 50% of the project, a Certified Development Company (CDC) provides a second-lien debenture backed by the SBA for up to 40% at a fixed rate, and you cover the remaining down payment. See the SBA 504 program page for details.

SBA 7(a) vs 504 at a Glance

The 7(a) program is the flexible general-purpose option; the 504 program is purpose-built for owner-occupied real estate and equipment. For a deeper comparison, see our guide on SBA 7(a) vs 504 loans.

What Lenders Check After the Payment Math

A payment you can afford is only the starting point. SBA lenders underwrite three things closely once the monthly number looks reasonable:

  • Debt service coverage. The SBA requires a minimum projected DSCR of 1.15x within the first two years (SOP 50 10 8), and most lenders target 1.25x or higher. Before you apply, it is worth taking a minute to check your DSCR.
  • Equity injection. The SBA generally requires a minimum 10% equity injection of total project cost for startups (one year of revenue or less) and complete changes of ownership.
  • Personal financial strength. Every owner of 20% or more must submit a Personal Financial Statement (SBA Form 413) documenting personal assets, liabilities, and net worth.

The PFS Connection

The same personal income, assets, and liabilities that shape your loan approval are exactly what SBA Form 413 asks for. Get that paperwork lender-ready before you submit your application, not after your lender asks twice.

Key Takeaways

  • SBA 7(a) loans max out at $5 million, amortize up to 10 years for working capital/equipment and 25 years for real estate, and usually carry a prime-plus-spread variable rate.
  • The FY2026 upfront guaranty fee is back on the statutory schedule: the bracket (2% / 3% / 3.5%) is set by the total loan amount and charged on the guaranteed portion, plus 3.75% on the guaranteed portion above $1M. The small-loan waivers ended, and the fee is commonly financed into the loan.
  • SBA 504 loans use a 50/40/10 structure: about 50% bank first lien, up to 40% fixed-rate CDC/SBA debenture, and a 10% down payment (15% or 20% for startups and special-use properties).
  • Since January 16, 2026 there is no minimum SBSS credit score for 7(a) small loans — creditworthiness is a lender judgment call.
  • Payment math is just the start: lenders also check DSCR (1.15x SBA floor, 1.25x typical target), equity injection, and every 20%+ owner's SBA Form 413.
