I've got raises as high as 206% by switching jobs. Most recent switch a little over 2 years ago resulted in a 20% raise which is much more typical. Never had more than a cost of living increase otherwise (2-3%), My strategy is to move when I stop learning. It maximizes both my enjoyment (learning challenges me and gives me motivation beyond a paycheck which is good for me and my employer.) and my potential earnings.
> 206% So it proves that it's possible to get decent people at 206% under the market :D
If that's how you do math, the sky's the limit.
206% means x3.06, so (s)he was previously making 1/3.06 of the new rate, which is roughly 32.7% of the new rate. Assuming the new rate was "at market", the old rate was 67.3% below market.
Math like that is why I make the big bucks. (I do not currently make the big bucks.)
