Use this calculator to determine the ROI (Return on Investment) for any direct mail/e-mail campaign. Just enter your program costs and projected program results under Input and click Calculate to instantly calculate the estimated ROI and other pertinent details like cost per piece, cost per new customer, and more. Use this tool to test different sets of assumptions to see how your program results might vary with different response rates and different conversion rates.

I have pre-filled in several numbers as an example. You may change the numbers and click calculate below.
