1. What is HMRC Yearly Average Exchange Rate?

The HMRC (Her Majesty's Revenue and Customs) yearly average exchange rate is calculated by summing daily exchange rates for a currency pair over a year and dividing by 365 days. This provides a standardized average rate for tax and accounting purposes.

2. How Does the Calculator Work?

The calculator uses the HMRC average rate formula:

\[ \text{Average Rate} = \frac{\sum \text{Daily Rates}}{365} \]

Where:

\(\sum \text{Daily Rates}\) — Sum of all daily exchange rates for the year
\(365\) — Number of days in a standard year
\(\text{Average Rate}\) — Resulting yearly average exchange rate

Explanation: The formula calculates the arithmetic mean of daily exchange rates over a full calendar year, providing a consistent benchmark for financial reporting.
