E-commerce website investment ROI depends on customer acquisition cost, repeat purchase rate, and average order value. Here’s a simple calculator framework:
ROI calculation
Annual contribution from website:
- Total annual orders × Average order value = Total revenue
- × Margin percentage = Gross profit
- − Annual website cost (build amortized + care plan + payment fees) = Net contribution
Payback period: Build cost ÷ Monthly net contribution = Months to payback.
Example: ₱180K Business tier e-commerce build
- Build: ₱180,000 amortized over 3 years = ₱5,000/month
- Care plan: ₱7,500/month
- Hosting and tools: ₱2,500/month
- Payment processing 3.5%: variable
- Total monthly cost: ~₱15,000–₱25,000
For payback in 12 months:
- Need ₱15,000+ monthly profit attributable to the site
- At 30% gross margin: ₱50,000+/month revenue from site
For payback in 6 months:
- ₱30,000+ monthly profit
- ₱100,000+/month revenue from site
