The difference in amounts between what Google makes per 1000 searches and what a profitable/sustainable search engine needs to make are quite vast. Can't remember the source but G make around ~$70 per 1000 searches. Bing make less than half than this, DDG less again. G commands higher rates because of higher competition for ads and also because of its retargeting and all the other methods that raise that per 1000 figure higher. To answer your question (sort of), Google's non-ad version would need to be expensive to break even with its current model.
