It's an excellent idea to run every recipe through one, no matter the source, just to make absolutely sure it's accurate. There are multiple online lye calculators out there but I prefer SoapCalc: http://soapcalc.net/calc/SoapCalcwp.asp

There are some subtle differences. Tallow is higher in lauric, myristic, and stearic acid, so it makes for a bubblier, harder, more cleansing soap compared to one made with lard instead. Depending on the degree to which the subtleties are noticeable enough to you in your finished soap to irk you, you may or may not find that you want to tweak your formula a little bit here and there to match up with what you are used to with your lard soap, soap quality-wise.
