Losing financial aid?

I know theres no spesfic answer but I'm asking for a ball park estimate.

I make about 18.000.00 a year. Sounds like a lot to me but after rent its not much.

Online it says a student can earn up to 7.167.00 or something before aid is deducted.

Do you think thatll mean ill lose my aid? What happens if I do? Ill have to pay out of pocket?
