SBA Loan Calculator

The SBA is not a lender. It insures loans that banks, credit unions, and some nonbank lenders make: if the borrower defaults, the SBA repays the lender most of the balance. The exact share depends on the program and the loan size; the percentages are set by statute and the current ones are posted at sba.gov. That insurance changes the lender's arithmetic. A file the bank would decline on its own becomes approvable when the government absorbs most of the loss, and the same logic lets the bank stretch the term and trim the rate. You pay for the guarantee through the upfront fee this calculator estimates, charged on the guaranteed slice rather than the whole loan. Roll it into the balance and the cost shows up as a slightly higher payment. At this calculator's defaults, a $350,000 loan at 7.5 percent over ten years runs about $4,155 a month without the fee and about $4,248 with it financed. In exchange you get longer terms and smaller down payments than a conventional loan of the same size would carry, at the price of more paperwork and a slower close.

Start with what the money is for. The 7(a) is the general-purpose program: working capital, equipment, real estate, buying a business, or refinancing expensive debt, up to $5 million. The 504 exists for major fixed assets and pairs a bank loan with a fixed-rate debenture issued through a Certified Development Company. SBA Express is a faster, smaller branch of the 7(a) that also allows revolving credit lines. Microloans cover the small end through nonprofit lenders and skip the guarantee fee entirely, which usually makes them the cheaper route below $50,000.

SBA eligibility runs in two layers. The agency sets baseline rules, and the lender stacks its own credit standards on top. Most declines happen at the lender layer: thin cash flow, low personal credit, or too little time in business. The agency layer is more mechanical, and you can check it yourself before applying.

A standard 7(a) takes 60 to 90 days, and the time splits roughly into thirds: document gathering and initial review, underwriting plus SBA authorization, then closing and disbursement. Deals with real estate run longest because appraisals and environmental reviews can add three to six weeks on their own. Two choices cut the timeline more than anything else. First, assemble the full file before you submit: three years of personal and business tax returns, current financial statements, a personal financial statement on SBA Form 413, and projections if the business is young. Feeding documents in one at a time is the most common reason applications stall. Second, pick a Preferred Lender. PLP banks hold delegated authority to approve SBA credit in-house, so your file never waits in the agency's queue. Before any of that, compute your own debt service coverage ratio: annual net operating income divided by all annual debt payments, the new loan included. Under 1.25, expect pushback. A longer term or a smaller request may solve the problem before a lender ever raises it.
