Which rates this uses

Conversions use official reference rates: the European Central Bank series for EUR, GBP, CAD, AUD, JPY, SGD, CHF and NZD, and the Banco Central do Brasil PTAX rate for BRL. These are the daily rates institutions quote, published once per business day.

That makes this converter right for reporting and planning, and wrong for spending: the rate your card or payout provider gives you includes a spread on top of the reference rate, usually between half a percent and three percent.

Converting MRR properly is harder than one rate

A single conversion of this month's MRR is fine for a quick answer. Historical revenue is a different problem: each invoice happened on its own date at that day's rate, so converting a year of MRR at today's rate quietly reshapes your growth curve.

This is why Kometrics converts per invoice, at the rate of the invoice date, when a workspace switches its reporting currency. Your history keeps its true shape instead of inheriting this week's exchange rate.

  • Quick answer: convert this month at the latest rate, which is what this tool does
  • Reporting: convert each invoice at its own date's rate
  • Never: convert a year of history at one single rate

Frequently asked questions

How current are the rates?

Reference rates are published once per business day by the ECB and the Banco Central do Brasil. The tool shows the date of the rates it is using under the results.

Why does my bank give me a different rate?

Banks and payment providers apply a spread on top of the reference rate, typically between 0.5% and 3%. Reference rates are the fair midpoint used for reporting, not a rate anyone will exchange your money at.

Which currencies are supported?

USD, EUR, BRL, GBP, CAD, AUD, JPY, SGD, CHF and NZD. They are the same ten currencies a Kometrics workspace can report in.

Should I convert my whole revenue history at one rate?

No. Each invoice should convert at the rate of its own date, otherwise your historical growth curve changes shape with every rate move. Kometrics does per-invoice-date conversion automatically when you switch reporting currency.
