    Yes the BASF calculator is indeed a useful tool for a very rough guide. The actual spf (ascertained from testing) will be influenced by a number of factors - emulsion type (w/o is preferred although doesn’t feel the best!), synergy between the filters, photostability, choice of emulsifier, rheology modifiers, emollients, particle size distribution to control film formation of the dispersed oil phase etc. You can also use spf boosters like sunsphere powder etc.
