The answer depends on your interest rate, and that can vary widely depending on what bank you choose. In addition, since savings account rates are variable, not fixed, you don't know how much you'll be earning on the account in the future. That said, if you score one of today's rates of around 5.00% APY and are able to earn that for a year, your $1,000 deposit would earn $50, or about $4/month. Compare that to the national average of 0.46% APY, which would pay you only $4.60 over an entire year, or about 38 cents a month. Of course, the more you can sock away, the more you'll earn. If you can average a balance of $10,000 over a year, a 5.00% APY savings account will pay you $500, or about $42 per month.
