How to figure out fed and CA state estimated tax after selling my house?

[ckhdpm]

House sold with taxable profit of $500K.  I want to pay lowest amount of estimated tax-both federal and CA state. If I pay 100% of federal tax paid in 2016, is this adequate to avoid a penalty?  Is there a simple way to pay the CA estimated tax similar to the federal rule? i.e. a percentage of what was owed in 2016?
