What would the TFM of the soap be if My current formula of soap is:

Olive oil -54gm
Shea butter-15gm
Coconut oil -25gm
Castor oil-6gm

Superfatted -6%
Water:Lye-2:1
Essential oils-4gm

I am lost. Sorry, but what is tfm?

Besides that, you have sugar going into your lye solution, and additives like sugar, salt, sodium citrate etc need to be predissolved into the water before adding your lye. I plugged the recipe into a lye calc, and you're making a tiny batch. Be sure your scale is very accurate, but with a 6% superfat, I believe you can pull it off (with a good scale of course).

Back to TFM, I haven't seen that term, can you clarify? It's probably one of those "OH, I get it now" things once you tell me hehe.

TFM?

By the way, that is much too small a batch of soap. You need to stick to batches of at least 500 g of oil. Small errors in weighing can be magnified by small batches.

I get total fatty matter of 63%. You can double check my math.

For each 100 g of soap we have:

glycerol 11.2 g
fatty acids 88.8 g
sugar 3 g
naoh 13.7 g
eo 4 g
water 21.3 g

I used the Soapcalc SAP values to calculate the glycerol and assumed the final product contains 15% moisture after the cure. So the total is 142 g and TFM = 88.8 / 142 = 62.5%
