This page of WLAN 802.11ac tutorial covers WLAN 802.11ac data rates.

Following table describes 802.11ac data rates for 20MHz,40MHz,80MHz and 160 MHz bandwidths for various modulation-coding schemes. All the data rates mentioned are with short Guard Interval. MCS 9 is not allowed for 20MHz BW. Also MCS9 is not supported for 6 SS in 80 MHZ BW and for 3 SS in 160 MHz BW. Values mentioned in 20 MHz is for 1 stream, and for 8 stream for 40,80 and 160 MHz. Channel width multiplication factors are 1 for 20MHz BW, 2.1 for 40MHz,4.5 for 80 MHz and 9 for 160 MHz. Values mentioned in 40MHz,80MHz and 160MHz are for 8 Spatial Stream(SS), to obtain for 1 stream one can divide by 8.

MCS Type 20 MHz(1 SS) 40MHz(8 SS) 80MHz(8 SS) 160MHz(8 SS)
MCS 0 7.2 Mbps 120 Mbps 260 Mbps 520 Mbps
MCS 1 14.4 240 520 1040
MCS 2 21.7 360 780 1560
MCS 3 28.9 480 1040 2080
MCS 4 43.3 720 1560 3120
MCS 5 57.8 960 2080 4160
MCS 6 65 1080 2340 4680
MCS 7 72.2 1200 2600 5200
MCS 8 86.7 1440 3120 6240
MCS 9 n/a 1600 3466.7 6933.3
