SaaS Marketing Campaign ROI Calculator

How to calculate Marketing Campaign ROI calculator?

Use campaign spend and customer lifetime value to determine the percentage return generated by a marketing campaign relative to its cost.

Core formula: ROI (%) = ((new_customers_acquired * lifetime_value) - total_campaign_spend) / total_campaign_spend * 100

Using the Marketing Campaign ROI calculator calculator: an example

Example values: Total spend $10,000; New customers 100; LTV $1,200.

Step-by-step calculation:

1. Calculate total customer revenue: 100 × $1,200 = $120,000.
2. Find net profit: $120,000 − $10,000 = $110,000.
3. Divide net profit by campaign spend: $110,000 ÷ $10,000 = 11.
4. Convert to percentage: 11 × 100 = 1100% ROI.

Frequently Asked Questions

What costs should I include in Total Campaign Spend?

Include all direct and attributable marketing expenses such as ad spend, creative production, tracking tools and agency fees. Exclude unrelated general overhead.

Should I use gross revenue or net LTV?

Prefer LTV net of direct service or support costs for a realistic ROI. Using gross revenue will typically overstate returns.

How often should I recalculate ROI?

Recalculate after each major campaign or at least quarterly to validate assumptions about acquisition volume and lifetime value.
