Understanding the Calculator Fields
Business Model Section
Pricing Model
What it is: How you charge customers for your service
Options:
- Monthly Subscription: Customers pay a fixed amount each month
- Annual Subscription: Customers pay once per year, often with a discount
- Usage-Based: Customers pay based on how much they use your service
- Tiered Pricing: Different pricing levels with varying features
Example: A project management tool might charge $10/month per user for the basic plan and $20/month per user for the premium plan.
Monthly Price
What it is: The amount you charge each customer per month
Formula: This is your primary revenue driver
Example: If you charge $50/month and have 100 customers, your monthly revenue would be $5,000.
Annual Discount
What it is: The percentage discount you offer for annual payments
Why it matters: Annual payments improve cash flow and reduce churn
Example: If your monthly price is $50 and you offer a 20% annual discount, customers pay $480 per year instead of $600.
Customer Metrics Section
Initial Customers
What it is: The number of customers you have at the start of your projection
Why it matters: This is your baseline for growth calculations
Example: If you're just starting, this might be 0. If you're an established business, this could be 1,000 or more.
Monthly Growth Rate
What it is: The percentage increase in customers each month
Formula: New Customers = Current Customers × (Growth Rate/100)
Example: If you have 100 customers and a 10% monthly growth rate, you'll add 10 new customers in the first month.
Monthly Churn Rate
What it is: The percentage of customers who cancel their subscription each month
Why it matters: Churn directly impacts your revenue and growth potential
Example: If you have 100 customers and a 5% monthly churn rate, you'll lose 5 customers each month.
Industry Benchmark
The average SaaS churn rate is between 5-7% per month. Premium B2B SaaS companies often achieve churn rates below 3%.
Cost Structure Section
Customer Acquisition Cost (CAC)
What it is: The total cost of acquiring a new customer
Formula: CAC = Total Marketing & Sales Costs ÷ Number of New Customers
Example: If you spend $3,000 on marketing and acquire 10 customers, your CAC is $300.
Monthly Fixed Costs
What it is: Costs that don't change with the number of customers
Examples: Salaries, office rent, software subscriptions, utilities
Example: If you pay $2,000 for office space, $3,000 for salaries, and $500 for software, your fixed costs are $5,500/month.
Variable Cost per Customer
What it is: Costs that increase with each additional customer
Examples: Payment processing fees, customer support, server costs
Example: If payment processing costs 2.9% + $0.30 per transaction and your monthly price is $50, your variable cost is about $1.75 per customer.
Time Horizon Section
Projection Period
What it is: How far into the future you want to project your finances
Common ranges: 12-60 months (1-5 years)
Example: A 36-month projection gives you a 3-year view of your business potential.
Ramp-Up Period
What it is: The time it takes to reach your full growth potential
Why it matters: Most businesses don't achieve maximum growth immediately
Example: If your ramp-up period is 6 months, your growth rate will gradually increase over those 6 months.
Ramp-Up Target
What it is: The percentage of your maximum growth rate you'll achieve after the ramp-up period
Example: If your maximum growth rate is 10% and your ramp-up target is 50%, you'll start at 5% growth and gradually increase to 10%.
Key Metrics Explained
Total Revenue
The sum of all revenue over your projection period. This shows the total income potential of your business.
Total Costs
The sum of all costs over your projection period, including fixed, variable, and acquisition costs.
Net Profit
Your revenue minus all costs. This is the actual profit your business generates.
Profit Margin
The percentage of revenue that becomes profit. Higher margins mean more efficient operations.
LTV (Lifetime Value)
The total revenue you expect from a customer over their entire relationship with your business.
Payback Period
How long it takes to recover your customer acquisition cost through customer payments.
Calculation Example
Let's walk through a simple example:
- Monthly Price: $50
- Initial Customers: 100
- Monthly Growth: 10%
- Monthly Churn: 5%
- CAC: $300
- Fixed Costs: $5,000/month
- Variable Costs: $5/customer/month
- Projection Period: 12 months
Month 1 Calculation:
- New Customers: 100 × 10% = 10
- Churned Customers: 100 × 5% = 5
- Net New Customers: 10 - 5 = 5
- Total Customers: 100 + 5 = 105
- Revenue: 105 × $50 = $5,250
- Variable Costs: 105 × $5 = $525
- Acquisition Costs: 10 × $300 = $3,000
- Total Costs: $5,000 + $525 + $3,000 = $8,525
- Profit: $5,250 - $8,525 = -$3,275 (loss)
As you can see, high acquisition costs can lead to initial losses, which is common in SaaS businesses.
The Power of Compounding Growth
SaaS businesses benefit tremendously from compounding growth. Even with moderate churn, consistent growth can lead to exponential customer growth over time. This is why SaaS companies are so valuable - they create predictable, recurring revenue streams.
Frequently Asked Questions (15 FAQs)
Most successful SaaS businesses aim for 70-80% gross margins and 20-30% net profit margins. However, early-stage companies often reinvest profits into growth, showing lower or negative margins initially.
Projections are estimates based on your inputs. Accuracy depends on how realistic your assumptions are. Use the calculator to test different scenarios rather than relying on a single projection.
CAC varies by industry and business model. A good rule of thumb is that CAC should be less than one-third of a customer's lifetime value (LTV). For B2B SaaS, CACs of $300-$1,000 are common.
Focus on customer success, regularly deliver value, gather feedback, and create switching costs. Industry benchmarks suggest 5-7% monthly churn for B2C and 1-2% for B2B SaaS.
Monthly pricing provides flexibility but higher churn. Annual pricing improves cash flow, reduces churn, but may require discounts to incentivize commitment.
Extremely important! A ratio of 3:1 or higher is considered healthy. This means each customer generates three times their acquisition cost in revenue.
Variable costs scale with customer count: payment processing fees, customer support, infrastructure costs (servers, bandwidth), and any per-user licensing fees.
Most SaaS businesses use 3-5 year projections. Shorter for early-stage companies focusing on product-market fit, longer for established businesses planning strategic initiatives.
Early-stage SaaS companies often target 10-20% monthly growth. Mature companies might achieve 3-5% monthly. The "Rule of 40" suggests growth rate + profit margin should equal 40% or more.
Monthly Churn Rate = (Customers Lost During Month ÷ Customers at Start of Month) × 100. Track this metric religiously as it's crucial for accurate forecasting.
Most businesses don't achieve maximum growth immediately. The ramp-up period accounts for the time needed to build momentum in marketing, sales, and market awareness.
Test different price points, analyze conversion rates, monitor customer feedback, and compare to competitors. The right price maximizes revenue, not necessarily customer count.
Aim for 12 months or less. Shorter payback periods mean faster reinvestment into growth. Venture-backed companies might tolerate longer payback periods for rapid scaling.
Many SaaS businesses experience seasonal fluctuations. If your business is seasonal, adjust growth rates accordingly or use the calculator's monthly performance table to model specific months.
While designed for SaaS, the calculator can be adapted for other subscription or recurring revenue businesses with similar cost structures and growth patterns.
Advanced Tips for Accurate Projections
Test Multiple Scenarios
Don't rely on a single projection. Create optimistic, pessimistic, and realistic scenarios to understand your business's potential range of outcomes.
Update Regularly
As you gather real data, update your projections. Compare actual performance to projections to improve the accuracy of your assumptions over time.
Balance Growth and Profitability
