Business Plan Software vs a Financial Model: Which Do You Need?

Short Answer: If a lender or investor has asked for a business plan, business plan software is the right tool: LivePlan ($15 a month billed yearly) is the most complete, and Upmetrics starts at $7 a month. If you're deciding whether to start or grow the business at all, you need a financial model first, the kind a finance consultant would build for $750 to several thousand dollars. For an owner-run business, we think Occam's Model is the best way to get that model: it starts from what your household needs and works out the business that pays for it, from $82.50 a month billed yearly.

We make Occam's Model, so weigh our first place accordingly. Every other price below was checked on the vendor's own site in September 2026, and each option gets a plain "pick it if" line, including the cases where you shouldn't pick us.

What's the Difference?

A business plan is a document: the market, the team, the strategy, and a financial section at the back. Its reader is someone else, usually a bank. A financial model is a set of connected numbers (prices, volumes, costs, taxes, cash) that you change to see what happens. Its reader is you.

Most first-time founders buy plan software because the word "plan" feels like the first step. But the question that decides whether to quit a job or sign a lease is a numbers question: at what volume does this business pay the owner enough, and how long does the savings last until it gets there? A 30-page document can leave that unanswered. A model can't.

You may need both. Build the model first, because the plan's financial section is only as good as the numbers behind it.

How We Picked

• Does it answer "will this pay me?" after tax, for your household, not only "will it be profitable?"
• Can you change an assumption and see the effect immediately?
• Does it show how long starting cash lasts?
• Does it produce something a lender will accept, if you need that?
• What does it cost compared with hiring someone to build it?

The Options at a Glance

1. Occam's Model: Best for Deciding Whether the Business Will Pay You

Occam's Model starts where a good consultant starts with a new venture: with the owner's life. You enter what your household needs, and the tax engine works out the extra monthly income the business has to provide. Then you design the business as it should look at month 24 (revenue, direct costs, operating expenses, your pay), price the startup investment, and shape the path month by month into a 24-month forecast that shows how long your starting cash lasts. Years three to five are optional.

An AI advisor on paid plans can review the design for blind spots, or draft a full plan from a description of the business two years out.

• Price: every input step is free with no card; the results and forecast need a paid plan, $82.50/mo billed yearly or $99 monthly. With a finance expert who answers within 24 hours, $416/mo billed yearly or $499 monthly.
• Pick it if: you're deciding whether to start, quit your job, or take on a bigger version of the business, and you want the answer a consultant would give.
• Skip it if: the lender wants a written plan with market analysis. We don't write one; use LivePlan or Upmetrics for the document and bring our numbers to it.

2. A Finance Consultant: A Model With a Person Behind It

A consultant or CPA advisor builds the model with you and explains it. A June 2026 guide from a CPA firm puts most consulting engagements at $100 to $400 an hour; a startup model often takes several hours.

• Pick one if: the decision is large (buying a business, a second location) and you want a person accountable for the numbers.
• Skip it if: you'll want to change assumptions every week. Each revision is billed time.

3. LivePlan: Best for the Plan Document

LivePlan guides you through writing a business plan and builds a full forecast (profit and loss, balance sheet, cash flow) with industry benchmarks, 550+ sample plans and lender-ready statements. The standard plan includes up to 10 what-if scenarios and connects to QuickBooks Online and Xero.

• Price: $15/mo billed yearly or $20 monthly; Premium, with an AI forecast builder, $30/mo billed yearly or $40 monthly. 35-day money-back guarantee.
• Pick it if: you need a polished plan for an SBA loan, a bank or an investor.
• Skip it if: your real question is what you'll take home. The forecast is built around the plan, not your household.

4. Upmetrics: A Lower-Cost Plan Writer

Upmetrics is AI-assisted business plan software with financial forecasting, aimed at startups and small businesses.

• Price: from $7/mo; 15-day money-back guarantee.
• Pick it if: you need a plan document on a tight budget.
• Skip it if: you need the numbers stress-tested. Check which tier includes the forecasting depth you need before buying.

5. ProjectionHub: Projections for a Loan Application

ProjectionHub offers free industry projection templates, all templates for $499 one-time, and custom projections built for you for $750. A plan plus projections costs $2,500.

• Pick it if: you need one set of SBA-ready projections and won't revisit them.
• Skip it if: you'll keep planning after the loan closes.

6. A Spreadsheet Template: Free and Fully Flexible

Free projection templates give you complete control. The cost is your time, plus the risk of a formula error nobody reviews.

• Pick it if: you're comfortable in Excel and the business is simple.

Common Questions

What is the best business plan software for startups?
For a lender-ready document, LivePlan is the most complete at $15 a month billed yearly; Upmetrics is cheaper, from $7 a month. If you're still deciding whether the business will pay you, build a financial model first.

Is a financial model the same as a business plan?
No. A plan is a document that describes the business. A model is a set of connected numbers you change to test the business. A plan usually includes a summary of the model.

Do I need a business plan to start a small business?
Only if someone asks for one, usually a lender. You do need to know the volume and price at which the business covers your household, which is a model question.

Can I use a financial model to get an SBA loan?
Lenders expect projections in a standard format, usually alongside a written plan. A model gives you the numbers; plan software or a service like ProjectionHub packages them.
