We describe a simple extension to aligned-spin fits for the final spin of a binary black hole system that includes the contribution from the in-plane spins. We show that this addition gives good agreement with the final spin from a suite of 752 numerical relativity simulations when applied to the aligned-spin fit from Healy, Lousto, and Zlochower (HLZ). This agreement is increased if one evolves the spins using post-Newtonian expressions. We also show that the unmodified HLZ final mass fit gives good agreement with the numerical relativity data.
