SBA Loan Calculator: 7(a) and 504 Payments and Fees
An SBA loan calculator finds the monthly payment from the loan amount, rate and term, then adds SBA's fees. For a 7(a) loan, SBA caps the variable rate at the base rate plus 3% on loans over $350,000, and up to 6.5% on loans of $50,000 or less. A $500,000, 10-year 7(a) loan at a 10.5% rate has a payment of $6,746.75 and an $11,250 upfront guaranty fee in fiscal year 2027.

SBA 7(a) loan calculator: payment, maximum rate and fees
The 7(a) program is SBA's main loan guarantee. The monthly payment is standard loan math. The SBA-specific parts are the rate cap and the fees:
| Loan size | Maximum variable rate | SBA guarantee |
|---|---|---|
| $50,000 or less | Base + 6.5% | 85% |
| $50,001 to $150,000 | Base + 6.0% | 85% |
| $150,001 to $250,000 | Base + 6.0% | 75% |
| $250,001 to $350,000 | Base + 4.5% | 75% |
| Over $350,000 (up to $5,000,000) | Base + 3.0% | 75% |
Enter the base rate your lender quotes, choose "SBA maximum" to see the worst-case payment, or enter the rate you were offered to check it against the cap. The calculator flags a quote above the cap.
The base rate field starts with an example value, not today's rate. Replace it before you rely on the output.
SBA guarantee fee schedule (fiscal year 2027)
SBA Information Notice 5000-881797, published September 3, 2026, sets the 7(a) fees for loans approved October 1, 2026 through September 30, 2027. The fee is charged on the guaranteed portion of the loan:
| Loan size (maturity over 12 months) | Upfront fee |
|---|---|
| $150,000 or less | 2% of the guaranteed portion |
| $150,001 to $700,000 | 3% of the guaranteed portion |
| $700,001 to $5,000,000 | 3.5% of the guaranteed portion up to $1,000,000, plus 3.75% above $1,000,000 |
| Maturity of 12 months or less | 0.25% of the guaranteed portion |
| $700,000 or less, manufacturer, food supply chain or rural business | 0% |
The lender's annual service fee is 0.55% of the guaranteed balance and cannot be passed to you. For 504 loans in FY 2027 (Notice 5000-881796), the upfront guaranty fee is 0.50% and the annual service fee is 0.203% of the outstanding balance, with both waived for manufacturers, food supply chain businesses and rural projects.
Worked example: a $500,000 equipment loan
A practice borrows $500,000 for 10 years to buy equipment. Assume a base rate of 7.5% (an example) and the SBA maximum for a loan this size.
| Step | Math | Result |
|---|---|---|
| Maximum rate | 7.5% + 3.0% | 10.5% |
| Monthly payment | $500,000, 10.5%, 120 months | $6,746.75 |
| Total interest | 6,746.75 × 120 − 500,000 | $309,610 |
| Guaranteed portion | 75% × 500,000 | $375,000 |
| Upfront fee | 3% × 375,000 | $11,250 (2.25% of the loan) |
| Fee financed into the loan | $511,250 at 10.5% | $6,898.55 a month |
Financing the fee adds about $152 a month. Compare that with paying it at closing, and with a plain bank loan in the loan amortization calculator.
SBA 504 loan calculator: the 50/40/10 structure
A 504 loan splits a project three ways under 13 CFR 120.801: the borrower puts in at least 10% of the cost, a Certified Development Company debenture covers up to 40% on a second lien, and a bank loan covers the rest on a first lien. 13 CFR 120.910 raises the borrower share to 15% for a business open two years or less or a special-purpose building, and 20% when both apply.
Example: a $2,000,000 building project for an established practice. Down payment $200,000, debenture $800,000, bank loan $1,000,000. At a 6.25% debenture and 7.25% bank rate, both over 20 years, the debenture payment is $5,847.43 and the bank payment is $7,903.76, so the combined payment is $13,751.19 with a blended rate of 6.81%. The upfront guaranty fee at 0.50% is about $4,000 on the debenture.
The rates in that example are placeholders. SBA sets the 504 rate when the debenture is sold. SBA also notes fees total approximately 3% of the debt, and the amount may be financed. The 504 program cannot be used for working capital or inventory.
What this calculator leaves out
It does not include lender packaging or closing fees, appraisals or insurance. It models the 7(a) variable-rate cap, so a fixed-rate quote should be checked against SBA's published fixed-rate maximums. It also does not model the 7(a) Working Capital Pilot, Express loans or the 504 refinance options.
If you are still sizing the project, start with the med spa startup cost calculator. Prospyr's med spa software page covers the operating side once the loan funds.
Frequently asked questions
What is the maximum interest rate on an SBA 7(a) loan?
For variable-rate 7(a) loans, SBA caps the rate at the base rate plus 6.5% for loans of $50,000 or less, plus 6.0% for $50,001 to $250,000, plus 4.5% for $250,001 to $350,000, and plus 3.0% above $350,000. The lender picks the base rate (commonly WSJ Prime) and the actual spread within the cap. SBA publishes fixed-rate maximums separately, so ask your lender which cap applies.
How much is the SBA guarantee fee for 7(a) loans in fiscal year 2027?
For loans with a maturity over 12 months, the upfront fee is 2% of the guaranteed portion for loans of $150,000 or less, 3% for $150,001 to $700,000, and 3.5% up to $1,000,000 of guaranteed portion plus 3.75% above that for loans over $700,000. The fee is $0 for loans of $700,000 or less to manufacturers, food supply chain businesses and rural businesses. These apply to loans approved October 1, 2026 through September 30, 2027.
How much of an SBA 7(a) loan does SBA guarantee?
For a standard 7(a) loan, SBA guarantees 85% of loans up to $150,000 and 75% of loans above $150,000. The guarantee covers the lender's loss if the borrower defaults. It is also the base the upfront fee is charged on, so a $500,000 loan has $375,000 guaranteed.
Who pays the upfront guaranty fee and the annual service fee?
The lender pays the upfront fee to SBA and is allowed to pass it on to the borrower, often by adding it to the loan balance. The lender's annual service fee (0.55% of the guaranteed balance for FY 2027) cannot be charged to the borrower. Check your closing statement to see which fees you are actually paying.
How long can an SBA 7(a) loan be?
Under 13 CFR 120.212, the term is 10 years or less unless the loan finances real estate or equipment with a useful life over 10 years. The maximum is 25 years including extensions. In practice, working capital and most equipment loans run up to 10 years and real estate up to 25.
How does an SBA 504 loan work?
A 504 loan funds real estate or long-life equipment with three parts: a bank first-lien loan for the balance (typically about 50%), a Certified Development Company debenture for up to 40%, and at least 10% from the borrower. The down payment rises to 15% for a business open two years or less or a special-purpose building, and 20% for both. SBA lists 10-, 20- and 25-year terms and a fixed rate pegged to the 10-year Treasury plus an increment.
Can a med spa or aesthetic practice get an SBA loan?
Many practices use SBA loans for equipment, buildouts, a purchase of an existing practice or real estate. Eligibility depends on the lender's credit review and SBA's rules, not on this calculator. A lender who already works with aesthetic practices can tell you whether lasers, injectable inventory or goodwill can be financed.
