/01 — What we calculate

## Five metrics
that matter.

/01

### ROI %

Return on investment. The headline number — what every dollar of spend earned back as profit.

/02

### ROAS

Return on Ad Spend. Revenue per dollar spent. Easier to compare across channels and campaigns than ROI.

/03

### CPA

Cost per acquisition. What each customer or lead actually costs you. The single most useful number for budgeting.

/04

### LTV ROI

Roll lifetime value into the equation and see if a "losing" channel is actually profitable over time.

/02 — Common questions

## Quick answers.

/01 What's the difference between ROI and ROAS? +

ROI accounts for total marketing investment and total profit. ROAS measures only revenue against ad spend, no other costs. Use ROAS to compare campaigns. Use ROI to evaluate whether your overall marketing investment is worthwhile.

/02 Should I calculate ROI by channel or overall? +

Both. Overall ROI tells you whether the total investment is justified. Channel-level ROI tells you where to shift budget. Brands tracking only blended ROI often subsidize underperforming channels with strong ones without realizing it.

/03 What ROI is "good"? +

Wildly varies by industry. SaaS brands often target 3:1 (300%); ecommerce often runs 2:1 (200%) on direct response; B2B services with high LTV can be profitable at 1:1 month-one because lifetime value flips the math. Use this calculator to model your own breakeven.

/04 Can I include CLV? +

Yes — drop in your customer lifetime value and the tool will compute Lifetime ROI alongside the immediate ROI. This is the right framing for any subscription, retainer, or repeat-purchase business.
