Plated 9mm bullets run about 8 cents each in 1000 piece lots. Primers have been averaging about 35 dollars per thousand or 3.5 cents each. Powder to load a single round of 9mm will cost about 2 cents or less depending on the powder used. Starline charges 130 dollars for 1000 9mm cases and I would expect that you can reload their cases a minimum of 20 times, so the case cost will run about 0.65 cents per load. Do the math and you have a per round cost of 0.1415 dollars, or about 14 cents per round. I don't care how dilligently you search the net you WILL NOT find 9mm ammo today for 7 dollars per box of 50.
As for the equipment cost, that isn't cheap. If you want to go first class you should plan on budgeting about 1 grand for a complete setup. Go bare bones and you can probably get the total cost for equipment down to about 300 bucks but you will spend a lot of time using scales and powder measures that are a bit of a pain to use and adjust. BTW, DO NOT buy a cheap digital scale, none of them will hold zero for longer than 5 or 10 minutes. Finding out your scale isn't zeroed after loading 100 rounds means you have 100 rounds to break down because you have no idea how much powder you put in each round. That cheap Lee balance scale may be a PITA to set and sensitive to vibration but it is reliable if placed on a vibration free table away from your press and reliable once you have it properly zeroed and set. In addition the cheap Lee powder measure does work well provided you choose a powder known for excellent metering properties even if it does leak like a sieve with a super fine powder such as Accurate #5 and is a royal PITA to get set perfectly.
BTW, reloading can be rather addictive. I got started because I didn't like paying 1 dollar per round for 308 ammunition. Now I build my own 308 loads and I'm using match grade bullets that cost 65 cents each, so I'm not really saving on my 308. However I am shooting much smaller groups. As for my handgun ammo, currently I'm loading 38 spl./357 Magnum and save a boat load on those calibers, 38 special can be loaded for about the same cost as 9mm. I also load the 40 S&W and 45 ACP and save about 50% over the cost of commercial ammo with both of these calibers. However, if my range time isn't limited I no longer think twice about running 300 45 caliber bullets downrange. Basically, I now shoot about twice as much per month than I did when I purchased all my ammunition. On the positive side I enjoy the quiet time spent reloading and am becoming a rather good shot.
). My cost varies between 9.75 cents and 11.5 cents per round depending on supplies. The cheapest non Russian ammo I can get is around $16.00/50 which is .32 per round. If I didn't handload I would have to cut my practice shooting by 3 to maintain the same competition level of ammo usage. I've amortized my equipment cost long ago and I bought the setup with all the "bells and whistles"(no, I won't comment on the color 
) when I started getting serious about handloading. It was initially expensive but I haven't had the need to "upgrade" or buy new "do-dads" for quite a while and don't foresee doing that in the near future. If I only shot a couple of hundred rounds a month, it would not make economic sense (but still a good hobby to have).
