What is unit economics, and does it matter for your startup?

Dan Kang · Mercury Free Beginner

This is a clean, plain-language walk through the numbers that decide whether your pricing actually works: contribution margin, CAC, LTV, and payback period. Written by Mercury's CFO, it connects the dots you need here, that moving from underpriced plans to value-based pricing and better-packaged tiers is what lifts LTV and contribution margin. Use it as a starting point to pressure-test whether the price you are considering leaves enough margin after you have paid to acquire the customer.

  • Contribution margin (price minus variable cost per unit) is the first thing to check, if it is thin or negative, no amount of scale fixes it.
  • Pricing directly shapes revenue per unit and LTV, so raising or repackaging price is often the fastest lever on your economics.
  • Read your LTV against CAC and payback period together, a price that looks fine in isolation can still lose money once acquisition cost is counted.
