It is really hard to estimate because it isn't quite apples to apples. With Aurora we pay for what we use, not what we provision. We used to have some big write spikes for about 5 minutes each hour and so had to massively over-provision IOPS. With Aurora we just pay for the IOPs we use on those spikes.

Right now, on a multiple of the traffic we had before we moved to Aurora we are paying less than half what we used to for IO.
