Monthly average exchange rate with a defined date range

A monthly average is not one convenient daily rate. Define the period, included observations, missing-date treatment and source before using it in a report.

Short answer

A monthly average exchange rate should identify the period, pair direction, included daily observations, missing-date treatment, averaging method, and source URL so the result can be recalculated from the underlying rows.

Problem to proof · Finance analysts, researchers, and reporting teams

The report says “monthly average,” but the spreadsheet actually uses the last rate somebody pasted.

Use a documented monthly average instead of an arbitrary single-day rate.

The problem

The report says “monthly average,” but the spreadsheet actually uses the last rate somebody pasted.

Without a defined date range, included observations, missing-date rule, and pair direction, two people can calculate different averages and both call them correct.

What good looks like

The report states the month, pair, observation set, averaging method, source URL, and link to daily rows behind the result.

  • The period is explicit.
  • Daily observations can be inspected.
  • The method is not confused with month-end.

FXpeek workflow

Make the monthly average reproducible from daily rows

  1. Define the periodState the calendar month or approved reporting range and pair direction.
  2. Inspect included rowsUse available daily observations and document how non-publishing days are treated.
  3. Keep method and sourceSave the monthly page, daily CSV or API URL, row count, and averaging note.

Reproducible worked example

A monthly revenue report needs USD/EUR average

Input
An analyst must translate a month of USD revenue into an EUR management report.
Before
The workbook uses the final visible daily rate and labels it “average.”
After
It stores period_start, period_end, observation_count, method, average_rate, and source_url.
How to verify
Download the daily rows, apply the documented method, and compare the recalculated average.
