DB Super power increases:
SSJ/SSJ God (anime) = SSJ/SSJ Blue 10% (manga) = 10
SSJ Blue (anime) = SSJ God & SSJ Blue (manga) = 100
Kaioken x10 SSJB = Full Power SSJB (manga) = 1000
Goku fought Beerus as a SSJ God and the power was kept with SSJ. We never saw it again in the anime, so we could assume that when Goku is a SSJ, he's using all of SSJG from a stronger base. SSJ2 and SSJ3 build on top of it with 2 and 4 times the power increase in succession until he becomes an 80 - it's still lower than SSJB.
The manga is a little bit harder to explain, but SSJB is always 10% of its full extent (100), either when they power up from base, bringing it to about SSJ, or when they use SSJG for the transition, with the difference being that Goku can use full power on top, and Vegeta the same by transforming briefly. Here's an example:
1. Goku transforms into SSJG (100) and then SSJB (1000), but his power is brought to 10%, so it's the same as the former. He completes his full power and goes back to 1000.
2. Vegeta transforms into SSJB (100), but his power is brought to 10%, until he learns SSJG (100) and briefly transforms before the power is cut so that he can enjoy 1000.
Ultimately, the anime was made simpler by cutting SSJG, and using Kaioken x10. However, Vegeta is left without a power up, so could he use a Blue Oozaru form?
