EACR — Effective Average Conversion Rate

EACR stands for Effective Average Conversion Rate. It is a display option that controls how foreign-currency balances are aggregated in the balance sheet, account running balances, and reports. It is a viewing choice, not a change to your data — your transactions are never altered, only how they are added up for display.

The question it answers

Bluecoins is multi-currency: an account can be held in any currency, and every transaction records the exchange rate that was in effect on the day it was entered. Over time, the rate you use for the account can change.

That raises a question: if you recorded a $100 transaction last month at a rate of 55.0, and the account’s rate is now 56.0, what should that $100 contribute to today’s balance?

• EACR off (default) — historical amounts are normalized to the account’s current rate. The $100 transaction is revalued at the current rate, contributing $100 × (55.0 ÷ 56.0) ≈ $98.21.
• EACR on — every transaction contributes its raw face value. Both a $100 transaction from last month and one from today contribute exactly $100.

How the calculation works

EACR off — the normalized view

Each transaction is adjusted by the ratio of the rate at which it was recorded to the account’s current rate:

contribution = transaction amount × (recorded rate ÷ current account rate)

Example — a USD account whose current rate is 56.0:

Transaction	Recorded rate	Raw amount	Contribution to balance
$100, entered when the rate was 55.0	55.0	$100	$100 × (55.0 ÷ 56.0) = $98.21
$100, entered when the rate was 56.0	56.0	$100	$100 × (56.0 ÷ 56.0) = $100.00
Total		$200	$198.21

The balance is consistent with the account’s current rate — the value you would expect if you converted the whole account today.

EACR on — the raw view

Each transaction contributes its face value, regardless of when it was recorded:

Transaction	Recorded rate	Raw amount	Contribution to balance
$100, entered when the rate was 55.0	55.0	$100	$100.00
$100, entered when the rate was 56.0	56.0	$100	$100.00
Total		$200	$200.00

The balance is the simple sum of the transactions. The default-currency equivalent appears as a secondary line (for example “$1,250.00 | ₱70,000.00”), and account running balances show both values side by side.

Why the difference matters

The gap between the two views is the currency conversion gain or loss embedded in your history — the same effect you see in the real world when you exchange money. If you exchanged into a foreign currency at a higher rate and the rate later fell, the value of that foreign currency is smaller than it was when you bought it; spending it after the drop costs you more in your local currency than the same purchase would have cost at the original rate.

• EACR off surfaces this effect: the balance reflects what the account is worth today, at current rates.
• EACR on ignores it: the balance reflects what you actually spent, in the currency you spent it.

Which view should you use?

You want to see…	Use
What the account is worth today, at current rates	EACR off (default)
The simple sum of what you spent or received, in face value	EACR on
A balance that matches your bank statement or actual cash flows	EACR on
A balance consistent with the account’s current conversion rate	EACR off

There is no “correct” answer — the toggle exists so you can choose the view that matches your mental model. Your data is identical either way; only the display changes.

Where to find it

The toggle is labeled “Calculate balance using EACR” and lives in the filter dialog on the balance sheet tab, and in the accounts timeline filters. It is off by default. When enabled, foreign-currency accounts show their raw balance as the primary figure and the default-currency equivalent as a secondary line.

Notes

• Transactions recorded in the account’s own currency are unaffected — normalization only applies to foreign-currency transactions.
• The default-currency equivalent is always shown the same way, regardless of the toggle.
• Turning EACR on or off never modifies your transactions, rates, or balances — it only changes how they are displayed.

See the balance sheet guide for how the report is built, and the multi-currency guide for how conversion rates work across the app.
