What is a startup financial model?

The basics

A startup financial model is a spreadsheet that turns assumptions about growth, pricing, hiring and costs into projected revenue, profit, cash and runway.

Financial modeling for startups starts from drivers, because there is little history to project from. A financial model for startup planning answers two questions: how fast can we grow, and how long will the cash last?

A good model is less a prediction than a map of which assumptions matter.

Using a financial model template for startup planning

Six steps

  1. Start with the drivers

    Customers, growth, churn and price produce revenue. Write each one down as a separate assumption.

  2. Plan the hires

    List each role with a start month and salary. Payroll is usually most of a startup's costs.

  3. Add the other costs

    Cost of revenue, marketing, software, rent and everything else, as fixed amounts or percentages.

  4. Turn profit into cash

    Add funding, then follow the cash balance month by month to see burn and runway.

  5. Summarize by year

    Investors read revenue, operating profit, customers, headcount and cash for three years first.

  6. Test a downside

    Lower growth or higher churn. If the runway still reaches your next raise, the plan is sturdier.

The drivers that move the model most

Sense checks

Whether you run a SaaS company or use it as a financial model for tech startup template planning more broadly, these six assumptions do most of the work.

Key startup model drivers and how to sense-check them
DriverWhat it changesSense check
Growth in new customersRevenue and every cost tied to revenueIs it in line with your pipeline and marketing spend?
ChurnHow many customers you keepDoes it match what your customers actually do today?
Revenue per customerRevenue and annual recurring revenueIs it your real average, after discounts?
Gross marginHow much of each sale pays for the teamDoes it include hosting, payment fees and support?
Hiring planPayroll, software costs and burnIs each hire tied to a revenue or product milestone?
Funding timingCash and runwayDoes the cash last until the round can realistically close?

Financial modelling tools for startups

Choosing

A financial model of a company template for an established business usually starts from past financial statements and projects them forward. A startup has little history, so its model starts from drivers and assumptions.

A spreadsheet is enough for most early-stage companies. Modelling software adds scenarios and investor-ready charts, and a fractional CFO builds and maintains the model for you.

Models get better with real numbers

Where Excello fits

Excello keeps your books current inside your own QuickBooks, Xero or Odoo, so each month's actual revenue, payroll and costs are ready to compare with the model. Books close within five business days of month-end, so each month's actuals reach the model early.

When you want the model built and maintained for you, Excello's fractional CFO work covers the financial model, scenarios, runway and hiring plans.

Frequently asked questions

What is a startup financial model?

A startup financial model is a spreadsheet that turns assumptions about growth, pricing, hiring and costs into projected revenue, profit, cash and runway. Founders use it to plan spending and to show investors how the business could grow.

What should a startup financial model include?

Revenue drivers such as customers, growth, churn and price, a hiring plan, operating costs, and a cash forecast with burn and runway. Most investors also want a simple annual summary covering three years.

How many years should a startup financial model cover?

Three years is the usual length for early-stage startups, built monthly so cash and runway are visible. Beyond that, the assumptions become guesses, so later years are best kept to an annual outline.

What is the difference between a financial model and a budget?

A financial model explores what could happen under different assumptions. A budget commits to a plan for the coming year, which you then compare with actual results each month.

Is there a startup financial model .xls version?

The template is an .xlsx file, the format every current version of Excel, Google Sheets and Apple Numbers opens. Older software that only reads .xls can usually convert the file when it opens.

Is this startup financial model template free?

Yes. The Excel template is free to download and use, with no sign-up needed. It includes assumptions, a hiring plan, a 36-month model and an annual summary, all linked by formulas.
