Calculator Use

• Select your Base Currency that you want to quote against. These are set at 1 base currency unit.
• Select your Quote Currency.

• Enter your ending quote (exchange rate #2).

This calculator will calculate the percentage change of the Quote Currency relative to the Base Currency and the percentage change of the Base Currency relative to the Quote Currency.

Calculating Currency Appreciation or Depreciation

Given 2 exchange rates in terms of a Base Currency and a Quote Currency we can calculate appreciation and depreciation between them using the percentage change calculation. Letting V₁ be the starting rate and V₂ the final rate.

The percentage change of the Quote Currency relative to the Base Currency is

The percentage change of the Base Currency relative to the Quote Currency is

A positive change is appreciation and a negative change is depreciation.

Example Calculation:

For example, calculating between GBP and INR; if a year ago 1 GBP = 42.553 INR and today 1 GBP = 54.054 INR we have V₁ = 42.553 and V₂ = 54.054.

The percentage change of INR relative to GBP is ((V₁ - V₂)/V₂) * 100 = ((42.553 - 54.054)/54.054) * 100 = -21.277%; Relative to GBP, INR Depreciated 21.277%.

The percentage change of GBP relative to INR is ((V₂ - V₁)/V₁) * 100 = ((54.054 - 42.553)/42.553) * 100 = 27.027%; Relative to INR, GBP Appreciated 27.027%.
