The price of champions

So a little while ago I wondered how much it would cost to buy every champion in league right now (so excluding Kindred). This is my findings for all those curious.

1st Tier of champs- 450 Ip/ 260 Rp 12 champions = 3120 Rp= 24$ with 5$ Rp bundle-20.8$ with 100$ Rp bundle

2nd Tier champs 1350 Ip/ 525 Rp 21 champs = 12285 Rp= 94.5$ with 5$ Rp bundle-81.9$ with 100$ Rp bundle

3rd Tier champs 3150 Ip/790 Rp 24 champs = 18960 Rp= 145.85$ with 5$ Rp bundle-126.4$ with 100$ Rp bundle

4th Tier champs 4800 Ip/880 Rp 33 champs = 29040 Rp= 223.38$ with 5$ Rp bundle-193.6$ with 100$ Rp bundle

5th Tier champs 6300 Ip/975 Rp 36 champs = 35100 Rp= 270$ with 5$ Rp bundle-234$ with 100$ Rp bundle

In total all champs cost 98505 Rp which equals 757.73$ with 5$ Rp bundle and 656.7$ with 100$ Rp bundle.

Feel free to use this information as you please and correct me if i made a mistake.
