87 gift points is not enough for even the smallest Robux reward in the sources I found. The lowest redemption shown is 100 Robux for 1,500 points , which works out to about 8.98 points per Robux or roughly 0.067 Robux per point.

So, at that rate, 87 points would be about 5 to 6 Robux , but Roblox/Microsoft Rewards typically only lets you redeem in set bundles, not fractional amounts.

Quick math

  • 1,500 points = 100 Robux
  • 87 points ≈\approx ≈ 87 / 15 = 5.8 Robux using the 1,500-point ratio
  • In practice, you would still need to reach the full redemption threshold

What that means

If your “gift points” are Microsoft Rewards points used for Roblox, you’ll need a lot more than 87 points to claim Robux. The nearest useful target is 1,500 points for 100 Robux.

TL;DR: 87 points is roughly equal to 6 Robux by math , but not redeemable yet because the minimum reward is much higher.
