How to Write a Business Plan (That Lenders Will Actually Read)

Why lenders ask for a business plan

A business plan is not a school assignment, and a lender is not grading your prose. When a bank or SBA lender asks for a plan, they are asking one practical question: if we lend this business money, where does the repayment come from? Every section of the plan either helps answer that question or gets skimmed.

That's actually good news. It means you don't need a beautiful 40-page document. You need a clear, honest one that shows you understand your costs, your market, and your cash flow. Plans matter most when you're seeking startup business loans, because a new business has no revenue history — the plan and its projections stand in for the track record that established businesses prove with bank statements.

Some lenders, especially online providers, never ask for a plan at all. Write one anyway. The discipline of building it — particularly the numbers — is the fastest way to find the holes in your idea while they're still cheap to fix.

The sections lenders actually read

A traditional plan has many sections, but lenders spend their time in a predictable handful:

• Executive summary. One page. What the business does, who buys from it, how much funding you're requesting, what the money buys, and how it gets repaid. Many readers decide here whether to keep reading — write it last, after the rest of the plan is done.
• The funding request. Be specific: the amount, the use of funds line by line, and the repayment source. "Working capital" is vague; "$40,000 for build-out, $20,000 for equipment, $30,000 for six months of operating runway" is a request an underwriter can evaluate. Your startup cost estimate feeds directly into this section.
• Financial projections. The most-read pages in the whole document. More on these below.
• Market and competition. Lenders don't expect a consulting-grade market study. They want evidence you know who your customers are, what they pay today, and why some of them will switch to you. Naming real competitors builds credibility; claiming you have none destroys it.
• Management and experience. Who runs the business and why they're capable of it. Industry experience is one of the strongest signals a startup can offer a lender.

Sections like company history, detailed org charts, and long product descriptions get skimmed. Include them briefly; don't let them crowd out the numbers.

Financial projections without the fantasy

Projections are where most plans lose credibility. Underwriters read hundreds of them, and the hockey-stick chart — flat, flat, flat, then vertical — is the fastest way to be filed under "not serious."

Build projections from the bottom up:

1. Start with units, not totals. Not "we'll do $300,000 in year one," but "we can serve 25 customers a week at an average ticket of $45, growing to 60 a week by month 12." Totals fall out of assumptions people can check.
2. Project cash flow monthly for the first year. Profit and cash are different things. A profitable month can still miss payroll if customers pay slowly. Monthly cash-flow projections show you — and the lender — whether the business survives its own growth.
3. Show the loan payment inside the projection. If you're asking for financing, the proposed payment belongs in your expense lines. Lenders will calculate whether projected cash flow covers debt payments with a cushion — the same math as our DSCR calculator — so run it yourself first.
4. Do a pessimistic case. Take your base projection, cut revenue by a meaningful margin, and see if the business still covers its obligations. If it only works in the optimistic case, the plan is telling you something.
5. Document every assumption. Price, volume, cost of goods, rent, wages — each number should have a one-line source: a supplier quote, a comparable business, a signed lease. Assumptions you can defend are the difference between a projection and a wish.

Lean vs. traditional format

There are two standard formats, and choosing is easy once you know the audience:

Most founders should start lean, then expand to traditional only when a lender or investor requires it. The lean plan forces clarity; the traditional plan adds evidence. If you're pursuing an SBA loan, expect the traditional format — SBA lenders typically want complete projections and a written funding request.

Use the SBA's free planning resources

You don't have to invent the structure. The SBA's Business Guide walks through both lean and traditional formats with examples, and it's free. Beyond templates, SBA resource partners — Small Business Development Centers, SCORE mentors, Women's Business Centers — offer free or low-cost help reviewing plans and projections. A second set of experienced eyes on your numbers before a lender sees them costs nothing and catches a lot.

The plan as a funding-readiness document

Think of the plan as the hub that every funding conversation spokes off of:

• The funding request section becomes your loan application's use-of-funds statement.
• The projections answer the cash-flow questions in underwriting — see our guide to business loan requirements for how lenders weigh them.
• The startup cost worksheet behind your numbers determines how much you actually ask for. Build it with the startup cost calculator so one-time and monthly costs stay separated.
• The entity and licensing details (covered in our LLC formation guide) show the business is legally ready to receive funds.

A plan built this way doesn't just support one application. When a lender declines — and declines happen to good businesses — you can take the same document to the next conversation, adjust the request, and keep moving.

Common mistakes that get plans set aside

• Round-number projections. Revenue of exactly $10,000 every month signals nobody did the work.
• No repayment source. The plan describes the business but never says what cash repays the loan.
• Ignoring the slow start. Most businesses take months to reach steady revenue; plans that assume full sales from day one read as inexperience.
• Asking for the wrong amount. Requesting too little is as damaging as too much — it suggests the founder will be back, underfunded, in six months.
• Hiding the risks. Naming your risks and your responses to them reads as competence, not weakness. Lenders assume the risks exist either way.

Write the plan for the skeptical reader. If it survives their questions, it will survive most of what the first year throws at it.
