1248 Microsoft Rewards points is not enough for a fixed Robux amount by itself , because Microsoft Rewards redeems Robux through specific gift-card offers, not a direct point-to-Robux exchange. The best public reference I found shows one Roblox redemption at 12,000 points for 800 Robux and 15,000 points for 1,000 Robux.

Rough estimate

Using that 12,000-point / 800-Robux example, the rate is about 15 points per Robux.

So 1248 points would be worth roughly:

  • 1248 Γ· 15 = about 83 Robux

What that means in practice

Microsoft Rewards redemption amounts can vary by region and offer, and some public discussions mention different point totals for different Robux cards. So the safest answer is:

  • Estimated value: about 80–85 Robux
  • Exact value: depends on the current Roblox reward offer in your region

Quick note

You usually can’t redeem Microsoft points straight into Robux; you redeem a Roblox digital card or similar reward first, then convert that into Robux.
