Would the Net pay be different if I got a weekly gross paycheck for $10,000 instead of $1,000?

I am a commission salesman in the state of Massachusetts. If I were to put in for $1,000(gross)worth of commissions and received $700(net)... would that mean if I put in for $10,000(gross) worth of commissions I would receive $7000(net)... and if not how big would the difference be?
