I would say at least a half on 9mm and 1/3 on .45ACP since those are the two rounds you listed I reload. Of course my estimates are high since I did not consider more than one reload per once fired brass, but with amortization of reloading equipment it is probably close to actual overall cost.
This is if you don't discount the enjoyment of reloading which offsets labor cost.
Since you shoot a lot, the cost savings will grow and grow as long as you can find reloading components at reasonable cost.
