Revenue, costs, and financing

Build the forecast around your subscriber and spending assumptions.

Set revenue timing, customer growth, churn, direct costs, operating expenses, and financing to explore the economics of a startup or early-stage SaaS business.

Four pricing tiers and start dates

Model four separate pricing tiers and choose the revenue start month for each stream.

One-time signup revenue

Include one-time revenue per signup in addition to recurring revenue, with the signup amount adjustable by year.

Growth and churn assumptions

Set monthly subscriber growth, subscriber churn, and revenue growth rates, with assumptions that can vary from year to year.

Direct costs and operating expenses

Enter cost of goods sold as a percentage of revenue. Input operating costs as dollar amounts for sales staff, executives, research and development, general and administrative expenses, and other cost lines.

Financing and debt service

Choose the financing month and use the built-in amortization schedule to calculate debt service. The forecast reflects financing timing and duration, and can also be run without financing.

Tax and cash flow adjustments

Adjust the corporate tax assumption by year and use the manual cash flow and tax-effect adjustment. The tax calculation accounts for the distinction between interest and principal repayments.

Financial reports and SaaS metrics

Review operating performance, funding, and customer economics.

The model brings the operating forecast together with financial statements, ownership analysis, valuation, and visual summaries.

Monthly and annual financial statements

Review an income statement, balance sheet, and cash flow statement on both a monthly and annual basis.

Cap table and investor summaries

Use the cap table and contribution and distribution summary to review ownership and investor cash flows alongside the operating forecast.

CAC, payback, and lifetime value

Review monthly customer acquisition cost and CAC payback, together with lifetime value and the LTV-to-CAC ratio.

DCF, IRR, and run-rate valuation

Evaluate discounted cash flow and IRR outputs, and use the run-rate multiple valuation to review an estimated value for each year of operation.

Annual and executive summaries

Review subscriber, revenue, cost, and cash flow results in the annual summary, including revenue by pricing tier. Use the executive summary for a higher-level view.

Financial and SaaS visualizations

View charts for financial flows, bank balance including financing effects, annual subscriber and recurring revenue changes, LTV, LTV-to-CAC, CAC, and CAC payback in months.

From operating targets to financial outcomes

See what your subscriber targets imply for cash flow and returns.

Revenue timing, subscriber growth, churn, pricing tiers, and signup fees establish the revenue forecast. Direct costs and operating expenses then shape profitability, while financing and tax assumptions affect the cash available to the business.

Review the financial statements and bank balance alongside CAC payback, LTV-to-CAC, and valuation. Change the assumptions to see how a different growth path, cost plan, or financing schedule affects the five-year results.

How to use the model

Build the forecast in four steps.

  1. Set up the revenue streams

    Define the four pricing tiers, revenue start months, signup revenue, and growth and churn assumptions for each year.

  2. Enter the cost plan

    Set COGS as a percentage of revenue and enter dollar-based operating expenses in the cost tables.

  3. Configure funding and taxes

    Enter financing timing and terms, review the cap table, and set annual tax assumptions and any manual cash flow or tax-effect adjustments.

  4. Review the financial and SaaS outputs

    Evaluate the statements, annual summary, bank balance, acquisition metrics, contribution and distribution summary, and valuation results.
