Your Ads/Sales income ratio?

Hey guys,
I’m reluctant to put Ads in my app since they ruin the experience and aren’t aesthetically pleasing.
I want to know what is your income as a ratio between Ads and in-app purchases.
I could go without a 25% Ads income and settle for the 75% from purchases, but anything above that then I’d have to put ads.

I want to know the income ratio you guys get.

Ads earn me about 50 times more than purchases (IAP+paid apps).

80% Ads 20% IAP for the games that include both

85% Ads 15% IAP.
