You have to give two preliminary donations to evaluate the quality of your baby gravy, and these donations (or "deposits" in sperm-banking parlance) are on the house; that is, they're not going to give you a red cent until they're sure your swimmers are the Michael Phelpses of the testicular tadpole world.

So if your first two donations are good enough, they'll bring you on as a paid donor. However, that means you'll be required to sign a contract, usually for six months to a year, stating you'll come in at least once a week to spank the monkey. Just to make sure you follow through, your paychecks are kept in escrow by the sperm bank until the end of the contract.

Sperm donation, as it turns out, has a pretty significant impact on your personal life, far beyond just having to take some time out each week to make your deposits. As mentioned above, you have to have an above-average sperm count for the whole [6 month] process to be viable, so as such, you're required to be abstinent two to three days before making a deposit. So if you're trying to maximize your profits by donating twice a week, that leaves one day per week that you can do with your genitals as you please.
