There is simply an enourmous amount of assumptions that would go into estimating anything else, because ms is the only correct metric. Lambda billing for a month? What on earth does that say? 10 invocations running 15 minutes? 90,000 invocations running 100ms? (Those two are equivalent btw). If I know my function takes around ~35ms ballpark, and I will probably invoke it 5,000 times per day, then I can calculate my monthly: 0.0000000021 $/ms * 35ms * 5,000 * 30 = 0.011 $/month. AWS usually shows a neat example of usecase and what the billing would be on their pricing pages.
