About Currency Adjustment Factor Calculator

A currency adjustment factor shares exchange rate movement between buyer and supplier at an agreed ratio rather than leaving it entirely with one party. Sharing typically produces a lower bid price than full supplier exposure, because the supplier prices unhedged risk expensively.

Formulas

Full impact

Impact = Foreign value x (Current rate - Base rate)

Adjusted local value

Adjusted = Foreign value x Base rate + Impact x Buyer's share %

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
Indicative estimate only. Fees, entitlements, limits and formulas vary by jurisdiction, statute, policy wording and the facts of the case. This is not legal, tax, insurance or financial advice — confirm with a qualified professional or the relevant authority.

Frequently Asked Questions

Is sharing better than a fixed rate?

Usually, yes. A fixed rate transfers all risk to the supplier, who prices it in at a premium above what a hedge would cost.

What trigger threshold is sensible?

Adjust only when the movement exceeds a dead band of 2-3%, so small fluctuations do not generate administrative work.
