Calculator
How many ad spots cover your 9x12 mailing costs?
Printing, USPS postage and your break-even point, from published rate cards rather than a guess. A 5,000-piece 9x12 drop costs $2,509 for printing and postage. In this illustration, 6 collected spots at the $477 advertised median cover that subtotal, before other expenses.
This calculator is for the shared-card operator selling ad space. It measures how collected spot revenue covers a mailing budget. It does not estimate the customers or sales an advertiser will get from the card.
What this does not include
- Design. Your time or a designer’s quote. The Canva sizes are here.
- Card processing. The applicable fees on your payment processor’s account.
- Software. Whatever you use to build the card and take the money.
- Your time selling. The largest real cost in this business and the one nothing prices.
The number that actually matters
Not the total. The break-even spot count.
Your print and postage are fixed the moment you choose your routes. Your revenue is not. So the whole business is the gap between the spot that covers your costs and the last one you sell — each additional collected spot contributes toward the other expenses and any eventual profit.
It is also why you collect before you print. Check collected payments against the full budget before committing to print.
