Yes, it will greatly affect your benefit and it is probably not wise to file for early retirement if you are still working and making a pretty significant income. First, as you probably know, your benefit will be reduced because you retired before full retirement age. If you start your retirement benefits at age 62, your monthly benefit amount is reduced by about 30 percent. The reduction for starting benefits at age 63 is about 25 percent; 64 is about 20 percent; 65 is about 13.3 percent; and 66 is about 6.7 percent." Second , See Social Security link: See link: https://faq.ssa.gov/link/portal/34011/34019/Article/3739/What-happens-if-I-work-and-get-Social-Security-retirement-benefits
"We use the following earnings limits to reduce your benefits: If you are under full retirement age for the entire year, we deduct $1 from your benefit payments for every $2 you earn above the annual limit. For 2016 that limit is $15,720."
So everything you make over $15,720 will reduce your benefit by $1 for ever $2 you make. At $80,000 minus the $15,720, you would be reduced on a base of $64,280 which would reduce your total benefit by $32,140 for the year. If you continue to work, it might be wise to wait until full retirement age (age 66) because this reduction will not make electing for your benefit worth it and you will be able to increase your benefit if you wait as well. If you hold off until age 70 then you can earn additional credits from age 66-70 and increase your benefits approximately 8% per year. Just food for thought.
