Learn how to interpret ROAS, CAC, LTV, conversion rate, profit margin, and ad budget metrics — then use GrowthCalc tools to plan your next move.
Each guide explains what the metric means, how to judge your numbers, and what to improve next.
Learn how margin, CAC, and costs affect whether your ROAS actually supports profitable growth.
A 3× ROAS can still lose money on thin margins. Compare ROAS to your break-even threshold before scaling spend.
Next step: Estimate break-even ROAS, then check if campaigns clear that bar after all costs.
Understand when acquisition cost is sustainable and how to compare CAC against customer value.
CAC works when LTV covers it with margin left for operations. Many teams use 3:1 LTV:CAC as a planning benchmark.
Next step: Calculate CAC and LTV, then compare the ratio before scaling paid or outbound channels.
Learn how conversion rate affects revenue, CAC, and paid growth efficiency.
No universal “good” rate — context matters. Ask whether your rate supports target CPA at current traffic cost.
Next step: Benchmark by traffic source, then find the funnel step with the largest drop-off.
Estimate a safer ad budget range from revenue goals, target ROAS, and margin assumptions.
Work backward from revenue targets. At 4× ROAS and a $40k goal, planning spend is roughly $10k per month.
Next step: Set a revenue goal and target ROAS, then derive a monthly budget range.
See why low-margin businesses need higher ROAS before scaling paid acquisition.
At 30% margin, you need roughly 3.3× ROAS to cover product cost alone — before overhead and platform fees.
Next step: Calculate true margin after fees and COGS, then set a minimum ROAS before scaling ads.
Combine revenue, ad spend, conversion, margin, and customer value into a practical action plan.
A growth audit connects acquisition, conversion, profit, and budget risk into one score with clear priorities.
Next step: Gather monthly metrics, then run a growth snapshot to prioritize the next 30 days.
Choose a goal to understand which metrics matter and why — before jumping into a calculator.
Diagnose whether paid channels are efficient before you scale spend.
Decide whether acquisition spend is sustainable over the customer lifecycle.
See whether product-level economics support paid growth and pricing decisions.
Move from single-metric checks to an integrated growth plan.
