The Metrics That Show Up in Every Board Meeting
A handful of numbers get asked about in nearly every business context, from a solo founder's spreadsheet to a board deck — profit margin, ROI, churn rate, and runway chief among them. Sixteen calculators here cover the core metrics used to judge whether a business is healthy, growing, or running out of time.

Highlights across profitability, growth, and startup finance:

- Customer Lifetime Value Calculator — projects total revenue expected from an average customer over their relationship with the business.
- Churn Rate Calculator — measures what percentage of customers are lost over a period, a leading indicator for subscription businesses.
- Break-Even Calculator — finds the sales volume where total revenue equals total costs.
- ROI Calculator — measures return relative to the cost of an investment or initiative.
Why Runway and Burn Rate Get Watched So Closely
For an early-stage company, runway is often the single most important number in the business — it sets the deadline for reaching profitability or closing the next funding round, and it changes every time burn rate shifts, whether from a new hire, a marketing push, or a slower sales quarter than planned. Lifetime value and churn rate connect to the same conversation: a business with high churn needs either a much lower customer acquisition cost or a much higher lifetime value to make its unit economics work, which is why LTV and CAC are almost always discussed together rather than in isolation.
Frequently Asked Questions
What's considered a healthy LTV to CAC ratio?
A ratio of 3:1 or higher is a common benchmark, meaning a customer generates at least three times what it cost to acquire them.
Is burn rate the same as monthly expenses?
Net burn rate accounts for revenue offsetting expenses, so a company with meaningful revenue can have a much lower burn rate than its raw expense total suggests.
