Prioritize Your Next Experiment with Unit Economics

Turn product questions into measurable decisions. Focus on the highest-impact move this week.

Who This Helps

This is for product managers who want to stop guessing and start deciding. You have a list of experiments, but you are not sure which one moves the needle. The Finance Basics for Operators program gives you the numbers to pick the winner.

Mini Case

Meet Viktor. He runs a SaaS product and sees three experiment ideas: improve onboarding, add a pricing tier, or cut a feature. He uses unit economics from the program. His contribution margin is 42%. One weak line is the customer acquisition cost, which eats 30% of revenue. He runs the numbers: improving onboarding could lift retention by 12% in 7 days. That is his highest-impact move. He skips the other two for now.

Do This Now (5 Steps)

  1. Grab your unit economics snapshot. Open your revenue and cost numbers for one product line. Calculate contribution margin: revenue minus variable costs, divided by revenue.
  1. Identify one weak line. Look for a cost that is above 20% of revenue. That is your leverage point.
  1. List your experiment ideas. Write down three product questions you want to test. Keep them specific, like "Does a 7-day trial increase conversion by 10%?"
  1. Score each idea by impact. For each experiment, estimate the change in contribution margin. Use a simple scale: high (over 5% lift), medium (2-5%), low (under 2%).
  1. Pick the top scorer. Run that experiment first. Ignore the rest until you see results. This is how you focus effort on the highest-impact move.

Avoid These Traps

  • Falling in love with a feature. Do not prioritize because it is fun to build. Let the numbers decide.
  • Ignoring cash rhythm. A great experiment can drain cash if you do not check runway first. Use the Runway Baseline mission from the program.
  • Overcomplicating the score. You do not need a spreadsheet. A simple high-medium-low works.
  • Forgetting the break-even scenario. Before you run the experiment, define what success looks like. The Break-even Scenario Card mission helps here.
  • Chasing every idea. Saying no to three experiments is harder than saying yes to one. Do it anyway.

Your Win by Friday

By Friday, you will have one experiment picked and ready to run. You will know exactly why it matters: it improves contribution margin by at least 5%. No more guessing. No more debate. Just one clear move that makes your product stronger. And you will have a finance operator card from the program to show your team. That is a win you can measure.
