A practical walkthrough for building base-case projections, listing assumptions, and stress testing the numbers before you apply.
October 30, 2026
Projections are the part of a loan request where a lender sees how you think. For a business purchase, a startup, or an expansion, the historical numbers show where the business has been, and the forecast shows where you expect it to go and what has to be true to get there. Houston-area business owners can avoid a scramble by building the forecast before the lender asks for it.
This guide walks through how to build base-case SBA loan financial projections that connect to your historical results, how to document your assumptions, how to run a downside test, and what lenders tend to look for. Approval is never automatic: eligibility, lender policy, and the full facts of the file all matter.
A forecast is an opinion until evidence supports it. Lenders usually read projections next to tax returns and interim statements and ask whether the next twelve to thirty-six months look like a reasonable extension of the past, adjusted for specific changes you can explain. In a business purchase, the question is often whether the new owner can maintain what the seller built. For a startup with no history, more weight falls on the owner's experience and on the market evidence behind each assumption.
For program basics, the SBA 7(a) loan overview explains common eligible purposes. Per SBA's Standard Operating Procedure (SOP 50 10) and the lender's policy (confirm the current version), 7(a) is SBA's most common program, and its loans are made by approved lenders with an SBA guarantee. Because program guidance and lender requirements can change, also review the current SBA 7(a) program page and confirm the lender's current checklist.
Most lenders want a small set of connected schedules rather than one spreadsheet tab. The exact mix depends on the transaction, the lender, and current SBA requirements, so ask the lender what format and time period it prefers before you build.
Underwriters often work backward. They ask how much the business must sell each month to cover every cost and every debt payment, then ask whether that level is realistic given past results. They compare first-year revenue with trailing results, check that margins match the historical pattern unless a reason is documented, and look for costs that appear in the history but quietly vanish from the forecast.
For example, suppose a business has trailing revenue of $1,200,000, a 40 percent gross margin ($480,000 gross profit), and $330,000 of operating expenses that already include a market-rate salary for the manager. The numbers below are hypothetical, and annual debt service on the new loan is assumed to be $110,000.
That last line is not a reason to hide the case. It tells the borrower and the lender how much cushion the plan has and what management would do, such as trimming hours or delaying a hire, if sales slip. Lenders set their own cushion above SBA's baseline, so ask the lender for the current minimum coverage it expects. Program-level requirements are in SBA SOP 50 10 (check the current revision), and each lender also applies its own credit policy.
1. Gather the historicals. Collect tax returns, year-end statements, and the latest interim profit and loss, and resolve any differences between them before you forecast.
2. Choose your drivers. Pick the few inputs that really move revenue and cost, such as customers, average ticket, billable hours, or contract value, and build revenue from them.
3. Write each assumption down. Note the source and the date, and mark anything that is an estimate rather than a commitment.
4. Add the transaction. Layer in loan payments, the owner's pay, one-time closing costs, and any equipment or hiring plans.
5. Stress test and explain. Run a flat-revenue case and a lower-revenue case, show cash after debt payments, and write two or three sentences on how management would respond.
Should projections be conservative or optimistic?
A base case built on reasonable, supportable expectations usually reads better than a best case. Many borrowers also add a downside case so the lender can see how the business handles slower months.
How far out should projections go?
It depends on the lender and the loan. Many ask for monthly figures for at least the first year, with annual figures after that. Ask the lender what period and format it wants.
What if the business has little or no history?
A startup or new location leans more on evidence outside the financials: market data, customer commitments, comparable businesses, and the owner's experience. Lenders often look more closely at those inputs.
Can projections make up for weak historical cash flow?
They can explain a change, such as a new contract or a cost that is ending, but lenders typically test the assumptions carefully and are cautious when a forecast conflicts with the history. Whether projections can support a request depends on the facts and the lender.
Strong projections read like a plan, not a wish. They start from history, name their drivers, include every cost, and show what happens when results fall short. A well-organized forecast cannot guarantee approval, but it gives the lender a clearer basis for its own decision.
