No. It won't.
The difficulty is currently estimated to go up by ~70% in less than 2 days. And then it will probably go up another 30-60% 1.5 weeks after that. And so on and so on.
Your income is asymptotic, not linear.
If you were to get 2 day shipping, and started mining right after the difficulty rise in less than 2 days, then you could make (with 1GHash/sec) ~2.47BTC/day or $17.43/day before you take out the cost of electricity. Cost of electricity for that rig will probably be (assuming you are going to use Air Conditioning during the summer) ~$3/day, so your incremental daily profit for just this coming difficulty round would only be ~$14.50.
This next difficulty round will probably only last 10 (or fewer days).
~$14.50/day x 10days = ~$145
And after that 10 days, the difficulty is likely to go up, let's say, 40% (even though 50% is just as likely). At which point, your daily profit would only be ~$9.45/day.
~$9.45/day x 10days = ~$94.50 + ~$145 = ~$239.50 (total profit from rig not including cost of rig)
And after that 10 days, the difficulty is likely to go up, let's say, 40% (even though 50% is just as likely). At which point, your daily profit would only be ~$5.90/day.
~$5.90/day x 10days = ~$59 + ~$239.50 = ~$298.50 (total profit from rig not including cost of rig)
So, after 1 full month, you have only paid off less than $300 of the total cost of your mining rig. That is less than 25% of the cost of your mining rig, not almost completely paid off like you estimated.But let's keep going.
~$298.50 + ~$33.50 + ~$15.40 + ~$2.40 = ~$349.80
After 2 full months, you might have paid off less than $350 of the total cost of your mining rig.
) but it's just not profitable like it used to be.
