How the budget is worked out

The ads manager counts orders received. But with cash on delivery, some are never confirmed and some parcels are refused at the door: only delivered orders pay. The calculator therefore works back from the deliveries you want to the orders you need to buy.

Result Calculation
Orders to win Target deliveries ÷ (confirmation rate × share delivered)
Monthly budget Orders to win × cost per order
Ads per delivered order Cost per order ÷ (confirmation rate × share delivered)
Maximum cost per order Margin before ads × confirmation rate × share delivered

Three levers before raising the budget

  • Confirmation rate. Going from 80% to 90% confirmed orders cuts the budget needed for the same deliveries by about 11%.
  • Refusal rate. Every point of refusals removed raises the share of orders that pay: confirm within the hour and describe products faithfully.
  • Margin before ads. A better price directly raises the cost per order you can afford.

Frequently asked questions

What ad budget should an online store plan?

Start from your sales, not a round number: delivered orders wanted, divided by your confirmation rate and by the share of parcels delivered, times your cost per order. With 75 deliveries wanted, 80% confirmation, 25% refusals and 10.8 TND per order, you need 125 orders, so 1,350 TND a month, 45 TND a day.

What cost per order is acceptable on Facebook?

One that leaves a profit once refusals are taken off: margin before ads times the confirmation rate times the share delivered. With 43 TND of margin, 80% confirmation and 25% refusals, the ceiling is 25.8 TND per order received.

Why do my Facebook orders not match my sales?

The ads manager counts orders placed, not orders delivered and paid. Unconfirmed orders and refused parcels do not show in its figures, so the real cost per sale is higher than the cost per result it displays.

Should I raise the budget when a campaign works?

Yes, in steps, while watching the cost per order: as long as it stays under the ceiling worked out here, every extra dinar pays. Better confirmation and fewer refusals often earn more than a bigger budget.

Does the calculator store my figures?

No. Everything is calculated in your browser; no figure is sent or saved.
