THE BUSINESS LOAN GUIDE

What business financing really costs

Business lenders quote costs in many ways: an interest rate, a rate over prime, a guaranty fee, a factor rate. This guide puts them on one scale. It covers term loans, the SBA 7(a) program with its rate caps and fees for loans approved from October 1, 2026, SBA 504 loans, merchant cash advances, and the debt service coverage ratio lenders use to decide how much you can borrow.

1In brief

The short answer

  • $250,000 at 9.5% over 10 years costs $3,234.94 a month and $138,193 in interest.
  • An SBA 7(a) loan of $500,000 carries an $11,250 guaranty fee and a variable-rate cap of 9.75% with prime at 6.75%.
  • A $50,000 cash advance at a 1.3 factor repaid over 6 months is about 109% APR.
  • Most lenders want yearly cash flow of at least 1.25 times your yearly debt payments.

3The maths

How a term loan payment works

A term loan is repaid in equal installments. Each month the lender charges interest on the balance at one-twelfth of the yearly rate; the rest of the payment reduces the balance. The payment is P × r ÷ (1 − (1 + r)−n), where P is the loan, r the monthly rate and n the number of payments. The same maths drives personal loans and mortgages; our loan calculator shows a monthly schedule for any fixed loan.

4Worked example

A term loan example

$250,000 at 9.5% over 10 years with a 2% origination fee
  1. Monthly payment120 payments$3,234.94
  2. Total interest$138,193
  3. Origination fee2%, taken from the loan$5,000
  4. Cash you receive$245,000
APR including the fee9.98%
5Fees

Origination fees and APR

Many lenders charge an origination or packaging fee. If it comes out of the loan, you pay interest on money you never receive, so the true cost is higher than the rate. The calculator turns the fee into an APR using the same method lenders must use for consumer loans. Our APR calculator explains the method and handles points and quoted payments.

6SBA 7(a)

SBA 7(a) loans in brief

The Small Business Administration does not usually lend directly. Under the 7(a) program, a bank or other approved lender makes the loan and the SBA guarantees part of it: 85% of loans of $150,000 or less and 75% of larger ones (50% for SBA Express). If the business defaults, the SBA repays the lender the guaranteed share. That lets lenders offer longer terms and lend to businesses they would otherwise turn down. The most a standard 7(a) loan can be is $5 million; SBA Express loans go up to $500,000.

7SBA 7(a)

SBA 7(a) maximum rates

Rates are agreed with the lender but cannot exceed the SBA’s maximums, which are a base rate (usually prime) plus a spread that depends on the loan size. Since March 1, 2026 lenders can also peg variable rates to SOFR or Treasury rates, but the cap is still worked out from prime.

Maximum 7(a) rates with prime at 6.75%
Loan sizeVariable capFixed cap
$25,000 or less13.25% (prime + 6.5)14.75% (prime + 8)
$25,001 to $50,00013.25% (prime + 6.5)13.75% (prime + 7)
$50,001 to $250,00012.75% (prime + 6)12.75% (prime + 6)
$250,001 to $350,00011.25% (prime + 4.5)11.75% (prime + 5)
Over $350,0009.75% (prime + 3)11.75% (prime + 5)

With a variable rate, the payment changes when prime does. The calculator holds the rate you enter for the whole term; try a higher rate to see what a rise in prime would do.

8SBA 7(a)

SBA guaranty fees for 2026–27

The SBA charges the lender an upfront guaranty fee, which the lender usually passes on to you. For loans approved from October 1, 2026 to September 30, 2027, with a term over 12 months, the fee is a share of the guaranteed part of the loan:

Upfront guaranty fee, term over 12 months
LoanGuaranteed partFee rateFee
$100,000$85,0002%$1,700
$150,000$127,5002%$2,550
$250,000$187,5003%$5,625
$500,000$375,0003%$11,250
$1,000,000$750,0003.5%$26,250
$2,000,000$1,500,0003.5% / 3.75%$53,750
$5,000,000$3,750,0003.5% / 3.75%$138,125

Loans of 12 months or less pay 0.25% of the guaranteed part. Loans of $700,000 or less to manufacturers, food supply chain businesses and businesses in rural areas pay no upfront fee, and SBA Express loans to veteran-owned businesses pay none. The lender also pays the SBA a yearly service fee of 0.55% of the guaranteed balance, which it may not charge to you. These tiers are the same as for fiscal year 2026.

9Worked example

An SBA 7(a) example

$500,000 variable-rate 7(a) loan at the 9.75% cap over 10 years
  1. SBA guarantee75% of $500,000$375,000
  2. Guaranty fee3% of the guaranteed part$11,250
  3. Loan with the fee added$511,250
  4. Monthly payment120 payments at 9.75%$6,685.63
  5. Total interest$291,025
APR including the fee10.28%

A $1,000,000 real estate loan at 9.75% over 25 years has a $26,250 fee, a payment of $9,145.30 with the fee added, and an APR of about 10.08%: the longer term spreads the fee more thinly.

10SBA 7(a)

SBA terms, collateral and guarantees

  • Term: generally up to 10 years for working capital, inventory and equipment, and up to 25 years for real estate.
  • Collateral: lenders take available business assets, and may take personal real estate, but a loan is not declined only for lack of collateral.
  • Personal guarantee: every owner of 20% or more must guarantee the loan in full.
  • Prepayment: loans of 15 years or more carry a fee if you prepay a large part in the first three years (5%, 3%, then 1% of the prepaid amount).
  • Equity injection: lenders usually want you to put in money of your own, often about 10% for a business purchase or startup.
11SBA 504

SBA 504 loans

The 504 program finances buildings, land and long-lived equipment at long fixed rates. A typical project is split three ways:

The Certified Development Company’s part is funded by SBA-guaranteed debentures sold to investors, up to $5 million per business ($5.5 million for manufacturers and certain energy projects). 504 loans cannot be used for working capital, inventory or rental real estate. For those, a 7(a) loan is the SBA option.

12Cash advances

Merchant cash advances

A merchant cash advance is not a loan in law: the provider buys a share of your future sales at a discount. You receive a lump sum and repay it, plus a fixed fee, from your card sales or bank account, usually each business day or each week. The fee is set by a factor rate, often between about 1.1 and 1.5. Because the cost is fixed, paying back sooner does not save you anything, and the faster you repay, the higher the effective yearly rate.

13Cash advances

Factor rate to APR

To compare an advance with a loan, the calculator finds the rate per payment at which the payments repay the cash you received, then multiplies by the number of payments in a year (252 business days, or 52 weeks), the same method used for APRs.

$50,000 advance, payments each business day
FactorRepayOver 6 monthsOver 12 months
1.15$57,50056.86%28.53%
1.20$60,00074.77%37.51%
1.30$65,000109.26%54.81%
1.40$70,000142.21%71.32%
1.50$75,000173.83%87.17%

Paid off in 3 months instead, the 1.3 advance is about 217% APR, at $1,031.75 each business day. A $1,000 fee taken from the advance raises the 6-month figure from 109% to about 118%.

14Cash advances

A cash advance against a loan

Cash advance, factor 1.3$15,000
Loan at 12% over 6 months$1,765
Loan at 11% over 6 months$1,616

The cost of $50,000 for six months. Advances are fast and easy to get, but they cost many times more than a loan. Using one advance to pay off another (stacking) can trap a business in a cycle of daily payments.

Read the contract

Check for a confession of judgment clause, personal guarantees, reconciliation rights if sales fall, and default fees. If you can, talk to a bank, a credit union, a Community Development Financial Institution or an SBA lender first.

15Lending decisions

Debt service coverage

The debt service coverage ratio (DSCR) is the cash your business generates for paying debt, divided by the debt payments due in a year. Lenders usually measure cash flow as net operating income, or EBITDA adjusted for owner pay. A DSCR of 1.0 means every dollar goes on debt; most lenders want at least 1.25.

The $500,000 SBA loan above, cash flow of $90,000 a year
  1. Yearly payments$6,685.63 × 12$80,228
  2. Yearly cash flow$90,000
  3. Cash flow needed for 1.25×$100,284
DSCR1.12×

At 1.12 the loan would be hard to approve. A longer term, a smaller loan or more cash flow would lift the ratio. Enter your figures under More options to check your own.

16Small print

Actual/360 interest

Many business loans charge interest on an actual/360 basis: each day costs 1/360 of the yearly rate, so a full year costs 365/360 of it. On $250,000 at 9.5%, a full year of interest is $24,079.86 on actual/360, against $23,750 on actual/365. Our simple interest calculator shows the effect for any sum and dates.

17Rules

Disclosures and your rights

The federal Truth in Lending Act does not cover business credit, so lenders need not show an APR. Some states have stepped in: California and New York require many commercial financing providers, including cash advance companies, to give an estimated APR and the total cost before you sign, and several other states have similar laws. Whatever the law, ask every provider for the total amount you will repay and how long it will take, then put each offer through this calculator.

18Taxes

Taxes on business borrowing

Interest on money borrowed for the business is generally a deductible business expense, and loan fees are usually deducted over the life of the loan. Repaying principal is not deductible. Larger businesses face a limit on business interest under section 163(j); most small businesses with average gross receipts under the inflation-adjusted threshold are exempt. If you are a sole proprietor, the deduction lowers your self-employment tax as well as income tax; see our self-employment tax calculator.

19Applying

Getting ready to apply

  1. Two or three years of business tax returns and year-to-date profit and loss statement and balance sheet.
  2. Personal tax returns and a personal financial statement for each owner of 20% or more.
  3. A clear use of funds and, for new or growing businesses, a business plan with projections.
  4. Details of existing business debt, so the lender can work out your DSCR.
  5. Your business and personal credit reports, checked for errors in advance.
20How to use it

Using the calculator

Choose the type of financing. For a term loan, enter the amount, the rate, the term and any origination fee. For an SBA 7(a) loan, the guaranty fee and the rate cap are worked out for you; under More options you can switch to a fixed rate, change the prime rate, apply the manufacturer and rural fee waiver, or pay the fee at closing. For a cash advance, enter the factor rate and the expected payoff time. Add your yearly cash flow to see the debt service coverage ratio.

Questions

Frequently asked

What is the payment on a $250,000 business loan?

At 9.5% over 10 years, $3,234.94 a month, with $138,193 of interest. A 2% origination fee taken from the loan raises the APR to about 9.98%.

What is the maximum interest rate on an SBA 7(a) loan?

Prime plus a spread set by loan size. With prime at 6.75%, variable-rate caps are 13.25% up to $50,000, 12.75% to $250,000, 11.25% to $350,000 and 9.75% above. Fixed-rate caps run from 14.75% down to 11.75%.

How much is the SBA guaranty fee?

For 7(a) loans over 12 months approved from October 1, 2026: 2% of the guaranteed part up to $150,000, 3% from $150,001 to $700,000, and 3.5% (3.75% on the guaranteed part over $1 million) above that. On $500,000 it is $11,250.

How much of a 7(a) loan does the SBA guarantee?

85% of loans of $150,000 or less and 75% of larger loans. SBA Express loans carry a 50% guarantee. The guarantee protects the lender, not you: you still owe the full amount.

Is there a fee waiver for manufacturers?

Yes. For fiscal year 2027, 7(a) loans of $700,000 or less to manufacturers (NAICS 31 to 33), food supply chain businesses and businesses in rural areas have no upfront guaranty fee.

What is an SBA 504 loan?

A long-term fixed-rate loan for real estate and major equipment. A bank usually lends about 50% of the project, a Certified Development Company about 40% backed by the SBA, and you put in about 10%. Terms are 10, 20 or 25 years.

How do I convert a factor rate to an APR?

Find the per-payment rate at which the daily or weekly payments repay the cash you received, then multiply by the number of payments a year. A $50,000 advance at a 1.3 factor repaid each business day over 6 months is about 109% APR.

What is a good DSCR for a business loan?

Most lenders want a debt service coverage ratio of at least 1.25: yearly cash flow at least 1.25 times your yearly debt payments. Below 1.0 the business does not earn enough to pay its debts.

Do business loans have to show an APR?

Not under federal law: the Truth in Lending Act covers consumer credit. Some states, including California and New York, now require commercial financing providers to disclose an estimated APR on many offers.

What is the longest term on an SBA 7(a) loan?

Generally up to 10 years for working capital and equipment, and up to 25 years when the loan finances real estate.

Will I need a personal guarantee?

For SBA 7(a) loans, anyone owning 20% or more of the business must give an unlimited personal guarantee. Most banks and online lenders ask owners for one too.

Is interest on a business loan tax-deductible?

Generally yes, as a business expense, subject to the business interest limit for larger businesses. Repayments of principal are not deductible. Ask a tax professional about your case.
