Financial Metrics Every Founder Should Track
Most founders have two numbers in their head at any given time: revenue and burn rate. Revenue tells them whether the business is growing. Burn rate tells them how long they have before the money runs out. These are important. They are also insufficient.
The founders who build durable businesses track a deeper set of financial metrics. Not because they love spreadsheets, but because these numbers are early warning systems. They tell you something is wrong months before it shows up in your bank balance.
Here are the metrics that matter, why they matter, and how to calculate them without a finance degree.
1. Gross Margin
What it is: Revenue minus the direct costs of delivering your product or service, expressed as a percentage.
Formula: (Revenue - Cost of Goods Sold) / Revenue x 100
Why it matters: Gross margin tells you how much money you have left to cover everything else -- salaries, marketing, rent, software, and eventually profit. A business with 80% gross margins has dramatically more flexibility than one with 30% gross margins, even if they have the same revenue.
Benchmarks:
- SaaS: 70-85%
- Professional services: 50-70%
- E-commerce (physical goods): 30-50%
- Managed services: 40-60%
The warning sign: If gross margin is declining quarter over quarter, you are either underpricing, over-delivering, or your costs are scaling faster than your revenue. Fix it before it compounds.
2. Customer Acquisition Cost (CAC)
What it is: The total cost to acquire one new customer.
Formula: Total Sales and Marketing Spend / Number of New Customers Acquired
Why it matters: CAC tells you how efficient your growth engine is. A business that spends $5,000 to acquire a customer worth $3,000 in lifetime value is burning money with every sale.
What to include: All marketing spend (ads, content, events, tools), all sales team compensation (base + commission), sales enablement tools, and CRM costs. Most founders undercount CAC by excluding salaries.
Benchmarks:
- B2B SaaS ($10K-$50K ACV): $500-$5,000
- SMB SaaS (sub-$1K ACV): $50-$500
- Professional services: $1,000-$10,000
3. Lifetime Value (LTV)
What it is: The total revenue you expect to earn from a customer over the entire relationship.
Formula: Average Revenue Per Account x Gross Margin x Average Customer Lifespan
Why it matters: LTV tells you the ceiling on what you can spend to acquire a customer. If LTV is less than 3x CAC, your unit economics are broken.
The LTV:CAC ratio:
- Below 1:1 -- You lose money on every customer
- 1:1 to 3:1 -- Unsustainable
- 3:1 to 5:1 -- Healthy target range
- Above 5:1 -- Consider spending more aggressively on acquisition
4. Monthly Recurring Revenue (MRR)
What it is: The predictable revenue your business generates each month from subscriptions or retainers.
Why it matters: Recurring revenue is worth more than project-based revenue because it is predictable. Investors value it more highly. Lenders consider it more reliable. And it makes cash flow forecasting dramatically easier.
Track the components:
- New MRR: Revenue from new customers this month
- Expansion MRR: Revenue increase from existing customers
- Contraction MRR: Revenue decrease from existing customers
- Churned MRR: Revenue lost from customers who left
Net New MRR = New MRR + Expansion MRR - Contraction MRR - Churned MRR. If Net New MRR is positive, you are growing. If it is negative, you are shrinking regardless of what your pipeline looks like.
5. Burn Rate and Runway
What it is: Burn rate is how much cash you spend per month. Runway is how many months of cash you have left.
Formula: Runway = Cash Balance / Monthly Burn Rate
Rules of thumb:
- Below 6 months: Red alert. You should already be fundraising or cutting costs.
- 6-12 months: Active management required.
- 12-18 months: Comfortable. Focus on growth.
- Above 18 months: Strong position. Take calculated risks.
The mistake founders make: Calculating burn rate from last month's expenses. Use the average of the last 3-6 months to smooth out one-time costs. And project forward -- if you are about to hire two people, include their fully loaded cost.
6. Net Revenue Retention (NRR)
What it is: The percentage of revenue retained from existing customers over a period, including expansion and contraction.
Formula: (Starting MRR + Expansion - Contraction - Churn) / Starting MRR x 100
Why it matters: NRR above 100% means your existing customer base generates more revenue over time without any new acquisition. This is the most powerful growth lever in any business.
Benchmarks:
- Best-in-class SaaS: 120-140%
- Good SaaS: 100-120%
- Healthy services: 90-110%
- Below 90%: Churn problem that will kill the business
7. Cash Conversion Cycle
What it is: The number of days between spending money to deliver your product and collecting payment from the customer.
Why it matters: A long cash conversion cycle means you are financing your customers' businesses. You pay your team on the 1st, deliver work by the 15th, invoice on the 30th, and get paid 45 days later. That is 75 days of float that can create serious cash flow crises even in profitable businesses.
How to shorten it:
- Invoice immediately upon delivery (or in advance for retainers)
- Require 50% upfront for project work
- Offer a 2% discount for payment within 10 days
- Automate invoice reminders at 30, 45, and 60 days
8. Revenue Per Employee
What it is: Total revenue divided by total headcount.
Formula: Annual Revenue / Number of Full-Time Employees
Why it matters: This is the simplest measure of organizational efficiency. It tells you whether each hire is contributing to revenue growth or diluting it.
Benchmarks:
- High-performing SaaS: $200K-$400K per employee
- Professional services: $150K-$300K per employee
- Early-stage startups: $100K-$200K per employee
Building Your Dashboard
You do not need a CFO or an expensive BI tool to track these metrics. Start with a spreadsheet updated monthly. The discipline of manually calculating these numbers teaches you how your business works at a mechanical level.
As you grow, automate the data collection. Pull revenue data from your billing system, cost data from your accounting software, and customer counts from your CRM. The point is not perfection. It is visibility. A founder who tracks these eight metrics monthly will see problems 2-3 months before they become crises.
