LTV:CAC Ratio Calculator

Entering your business variables

To begin the analysis, gather your records for the trailing twelve months (TTM) or current reporting period. Ensure that all inputs align to the same currency and time horizon (monthly or annual) to preserve ratio integrity. Standard outputs are updated instantly in real-time as you modify parameters. For LTV CAC Ratio Calculator, apply this guidance to recurring revenue, customer counts, acquisition spend, churn, expansion, and funnel assumptions, then compare the result against SaaS operating metrics, cohort signals, efficiency ratios, and growth thresholds.

Adjust inputs using the left configuration card. Use the Conservative, Base, and Optimistic presets to model scenario runs. Additionally, verify the quality of your historical transaction and customer data. Inaccurate entries, duplicates, or improper accounting definitions can skew key performance indicators and lead to incorrect operational decisions. For LTV CAC Ratio Calculator, apply this guidance to recurring revenue, customer counts, acquisition spend, churn, expansion, and funnel assumptions, then compare the result against SaaS operating metrics, cohort signals, efficiency ratios, and growth thresholds.

Interpreting the outputs

The system returns core metrics at the top of the results card, paired with an SVG graph showing the visual distribution. Scroll down to review the two-dimensional sensitivity grid, which shows how shifts in key assumptions alter your operational metrics. For LTV CAC Ratio Calculator, apply this guidance to recurring revenue, customer counts, acquisition spend, churn, expansion, and funnel assumptions, then compare the result against SaaS operating metrics, cohort signals, efficiency ratios, and growth thresholds.

If any warning prompts appear, review the metrics against VC benchmarks. For example, high growth rates are beneficial, but high churn rates signal systemic issues. Furthermore, use these outputs to run sensitivity analysis. Understanding how small changes in individual inputs, such as pricing tiers or customer acquisition costs, affect your overall profit margin helps build a resilient growth model. For LTV CAC Ratio Calculator, apply this guidance to recurring revenue, customer counts, acquisition spend, churn, expansion, and funnel assumptions, then compare the result against SaaS operating metrics, cohort signals, efficiency ratios, and growth thresholds.

Sample unit economics inputs

Let's evaluate a mid-stage B2B SaaS company:

• Customer Lifetime Value (LTV) = $3,600
• Customer Acquisition Cost (CAC) = $900
• Annual Customer Volume = 500
• LTV Confidence Adjustment = 10%

Step-by-step LTV:CAC math

Calculate Adjusted LTV:
Adjusted LTV = $3,600 * (1 - 0.10) = $3,240/customer.

Calculate LTV:CAC Ratio:
LTV:CAC Ratio = $3,240 / $900 = 3.60x.

Calculate Net Unit Value:
Net Unit Value = $3,240 - $900 = $2,340/customer.

Calculate Total Annual Economic Value:
Annual Value = $2,340 * 500 = $1,170,000/year.
