If you go with having his tail cut off not reducing his power (seriously, i don't think it does;
AT had definitely forgotten about that by then), his Oozaru is 25.000
If you go with his power being reduced post tail loss, his Oozaru was 30.000 or a little higher.

Goku: “Even if I raise the Kaio-Ken to x5, it still won't have any effect on him!!!!”
Oozaru Vegeta would still have to end up above 40k based on that. I doubt Goku was factoring in his current condition since, as I've already stated, raising the Kaioken to x5 in his state was an impossibility anyway.
Also, this statement after the battle.

Goku: “I trained under Lord Kaio… I thought I’d hit the peak of power… But Vegeta was…so far above me…! I was shocked… Scared…”
Sounds like he was factoring in their power ups such as Kaioken and Oozaru if he were to bother bringing up "the peak of power".
