How to Write a Business Plan a Lender Will Read
A lender reads a business plan for one thing: whether the numbers will cover the payment. Here is how to build a plan from the numbers out — in the format the SBA describes — and how to check it against federal data before anyone else does.

Every section of a plan rests on four figures. Work them out before you write a sentence:
Startup budget
Every purchase before opening day — equipment, vehicle, deposits, licenses, first inventory — plus a cash reserve to carry you while sales build. Use real quotes, not guesses.
Monthly costs
Split them in two: fixed costs that arrive whether you sell or not (insurance, rent, software, wages, the loan payment), and variable costs that rise with each sale (materials, food, card fees).
Break-even
Fixed monthly costs divided by the share of each dollar you keep after variable costs. If a food truck keeps 65¢ of every dollar and has $7,629 of monthly costs, it needs about $11,736 in sales a month. Try the break-even calculator.
A realistic first year
New businesses rarely open at full speed. Our plans assume year one runs at 55% of full volume and year two at 80%, reaching full volume in year three — and the plan says so, so a lender can see it.
2. Check your market with federal data
A lender wants to know the business has customers in your area — and that you know the competition. Three free federal sources answer that for almost any small business and any county:
| Question | Federal source | What it gives you |
|---|---|---|
| How many competitors are here? | Census County Business Patterns | Employer businesses by industry code in your county, and how the count changed since 2019 |
| What do they take in? | Census Economic Census and Nonemployer Statistics | Average yearly sales for businesses with employees and for self-employed owners |
| What will staff cost? | BLS Occupational Employment and Wage Statistics | Hourly wages for the job you’ll hire for, in your metro or state |
| What will the loan cost? | Federal Reserve prime rate | The base most small-business loan rates are quoted against |
Main Street Plans pulls all four for your county automatically — see how.
3. Write the sections
The SBA describes the traditional format that lenders and investors commonly request. Write the executive summary last — it is a summary of everything else.
Executive summary
What the business is, where, who runs it, how much you need and what for. One page.
Company description
The problem you solve, who you serve and why you’ll win against the businesses already there.
Market analysis
Your industry, your customers and your competitors — with counts and averages for your county, not national clichés.
Organization and management
Legal structure, who does what, and the experience that makes you credible.
Service or product line
What you sell, at what price, and why customers will pay it.
Marketing and sales
How the first hundred customers find you and why they come back.
Funding request
How much, for what, and on what terms — and how the payment is covered.
Financial projections
Startup budget, monthly costs, break-even and the yearly projection, with every assumption labelled.

4. Pressure-test it before a lender does
Every Main Street Plans plan runs the same four checks against federal data. You can run them by hand:
- Sales vs. the local average. If your year-three sales are well above what similar businesses in your county average, explain why — or lower them.
- Staffing vs. the industry. If similar businesses average several employees and your plan has none, your hours and wage costs are probably missing.
- Margin vs. payroll. With staff on payroll, a margin above 40% usually means a cost is missing. Food truck businesses with employees spent 23.4% of sales on payroll alone in the 2022 Economic Census.
- A first-year loss. Common and fine — if your reserve covers it. Show the reserve.
Break-even for five common small businesses
With typical starting assumptions and an example loan at the SBA’s maximum 7(a) rate for its size, here is what five businesses need to sell each month to cover their costs:
| Business | Staffing | Cost to open | Monthly costs* | Kept per $1 of sales | Break-even sales / month |
|---|---|---|---|---|---|
| Food truck | Owner + helper | $113,916 | $7,629 | 65¢ | $11,73638.1 orders per working day |
| Cleaning business | Owner only | $4,610 | $420 | 86¢ | $4881 cleaning visit per week |
| Landscaping business | Owner + helper | $44,867 | $3,883 | 80¢ | $4,8543.9 service visits per working day |
| Junk removal business | Owner + helper | $56,152 | $6,019 | 70¢ | $8,5991.3 jobs per working day |
| Vending machine business | Owner only | $23,350 | $647 | 40¢ | $1,6175 machines |
*Fixed costs, wages and the example loan payment in year one. “Owner only” break-even covers the business’s costs, not the owner’s pay. Your own quotes, prices and city change every figure.
Questions
How long should a business plan be?
The SBA describes a traditional plan as dozens of pages and a lean plan as typically one page. For a loan, use the traditional format: lenders read the executive summary, funding request and financials first, so put the effort there rather than into length.
Do I need a business plan to get an SBA loan?
The SBA’s guide recommends having a business plan, an expense sheet and five-year financial projections when you apply for a loan. Your lender decides what it requires — ask before you write.
How many years of projections do I need?
The SBA suggests a five-year forecast with the first year in the most detail. The first year matters most because it is built on things you can check: quotes, prices, local wages. Ask your lender how far out they want to see.
Can I write a business plan myself?
Yes. Most of the work is the numbers, not the writing: a startup budget, monthly costs, a realistic first year and the local market. Get those right and the sections follow from them.
What is the most common mistake?
Projections that don’t match the local market — sales far above what similar businesses in the area take in, or profit margins that leave nothing for wages. Check your year-three sales against the Census average for your industry and county before a lender does.
