Discount factor - NPV

You can't use tables and you will have to calculate discount factors from first principles. So for a rate of 12.5 (where ^ means raise to the power): Yr 1 factor = 1/(1 +0.125)^1 Yr 2 factor = 1/(1 +0.125)^2 Yr 3 factor = 1/(1 +0.125)^3 etc

Your calculations are correct.

Thank you so much.
