I reckon it should be 143.71%, which is not far from my rough 150:1 for UK.
There must be a Doctor of Mathematics on this thread but my understanding is that 100% is the same again so 100% inflation means double the original. 143.7% would give a result that is 1.437 times the original.
1437.1% is 14.37 times the original which is closer but not the same as the on line calculator.
However the calculations I am using are inflation figures. Wages have outstripped inflation considerably over the last seventy odd years.
That's from a successful O level Maths graduate.
My head hurts; I think I need a drink.
