First of all, you need to figure out whether or not you're building a consumer or business product. "Would I give this to somebody as a gift?" If Yes, you have a consumer product. If No, you probably have a business product. For business products you want to think in terms of expense accounts. You can bet that ~$20-$30 is super easy on up to ~$300-$500. The problem with subscriptions is that it can scare some people off who only need to use the product once. For consumer products, I have no idea. I just know that consumers are generally more discretionary with how they throw their money around. Education customers will just give you a lot of buzz but not much money (from my experience).
