Direct Mail ROI Calculator

Direct mail ROI = (gross profit from orders − mailing cost) ÷ mailing cost × 100. Gross profit is pieces × response rate × order value × margin. In the example: 5,000 × 1.5% × $150 × 50% is $5,625. Minus the $3,750 cost is $1,875, divided by $3,750 is 50%.

The ANA's 2018 response rate report put house lists, your own customers, at about 9% and prospect lists at about 5%. Many small mailings see less, often 1% to 3% on cold lists. Your offer and list matter more than design. A 1% response on a cold list can still be profitable if your order value and margin are high enough.

It's the cost per piece divided by the gross profit per order. In the example, $0.75 ÷ ($150 × 50%) is 1%. Any response above that makes money. Lower your piece cost or raise your order value and the break-even falls. The results show yours for every set of inputs.

Any positive ROI on gross profit means the mailing paid for itself. Surveys of marketers often report direct mail ROI over 100% for house lists. Prospecting mailings often run near break-even on the first order and profit on repeat orders. At 3 orders per customer, the example returns 350%.

Postcards often cost $0.30 to $1.00 each with printing and marketing mail postage. Letters in envelopes often cost $0.75 to $2.00, and catalogs more. USPS Every Door Direct Mail is among the cheapest options for local reach. Include list rental, design and any mail house fees in your cost per piece.

Divide your budget by the cost per piece to get pieces mailed, then enter a low response rate from past mailings or industry ranges. A $3,750 budget at $0.75 mails 5,000 pieces. Run it at your low and high response guesses. If the low case still breaks even, the mailing is a safer bet.

Using revenue instead of gross profit, which ignores product costs. Leaving out design, list and mail house fees. Counting only orders with the code, which misses people who buy online without it. And ignoring repeat orders, which often turn a break-even mailing into a profitable one.

Give each mailing a unique discount code, phone number, QR code or short web address. Compare sales in the mailed area or list against a similar group you didn't mail, to catch buyers who skip the code. Most mailings get most of their responses within 2 to 4 weeks.

Direct mail costs far more per contact but stands out in a quiet mailbox, and it reaches people you don't have emails for. Email is cheaper to send and to repeat. A common pattern is mail to win new customers, then email to keep selling to them. Compare both with our email marketing ROI calculator.

Response often builds over 2 to 3 mailings to the same people, because familiarity helps. Run the calculator for each mailing on its own. If the first one only breaks even, a second at the same cost can still profit if its response holds.
