When you subscribe to Roblox, you can earn up to 2,200 Robux per month. To earn additional Robux, you must make a purchase and subscribe. The three tiers include:
1. Pay $4.99 for 400 Robux and get an extra 50 when you subscribe
2. Pay $9.99 for 800 Robux and get an extra 200 when you subscribe
3. Pay 19.99 for 1,700 Robux and get an extra 500 when you subscribe
