Using the AdvertiseCast Pricing Calculator, estimates suggest an advertising campaign on a podcast with a reach of 50000 with two ad spots at the March average rate of $22.10 would cost around $2,210, depending on variables like duration.

According to RadioResults, the average CPM for a radio ad in Australia is slightly cheaper than the US podcasting average at $20 per 1000 listeners during peak time or closer to $10-$15 for off-peak hours.
