Question 1

How do I calculate ROI on handwritten mail?

Accepted Answer

Multiply pieces by response rate to get responses, then by conversion rate to get customers, then by the value of a customer to get revenue. Subtract total campaign cost (pieces × cost per piece). ROI = net profit ÷ total cost. This calculator does it for you and also shows your break-even response rate.

Question 2

What is a realistic response rate to plug in?

Accepted Answer

Well-targeted handwritten campaigns often see 1%–5%, and higher (5%–15%) in real estate and home services with strong timing. Use a conservative number first. See the response-rate guide for sourced benchmarks.

Question 3

What is break-even response rate?

Accepted Answer

The response rate at which the campaign exactly pays for itself. If your expected response is comfortably above it, the campaign has margin for error; if it is below, rework the list, offer, or cost before mailing.

Question 4

Should I use revenue or gross margin?

Accepted Answer

For a truer ROI, enter the gross-profit value of a customer (revenue minus cost of goods) rather than top-line revenue. The calculator labels the field "value per customer" — use whichever you can defend.
