Foreign Exchange Impact Calculator
Quantify the P&L and balance sheet impact of exchange rate movements on foreign-currency revenue, costs, and net assets with sensitivity analysis.
About this calculator
A company with foreign-currency revenue, costs, or a foreign subsidiary carries currency risk even without touching a single derivative — this calculator separates that risk into the two forms accountants and treasurers actually track. Transaction exposure is the P&L effect: it revalues your foreign-currency revenue and costs at the original rate versus the current rate (revenue times rate, both ways, then subtract) to isolate exactly how much of the change in profit came from currency movement alone rather than the business itself, and separately compares current revenue against a budgeted rate to show budget variance. Translation exposure is the balance-sheet effect: it nets foreign assets against foreign liabilities and revalues that net position at the original versus current rate, producing an unrealized translation gain or loss — unrealized because nothing was actually bought or sold, the asset just reports differently in home-currency terms.
A built-in sensitivity check then stress-tests one further rate shock on top of the current rate to show how much additional profit swing an extra move of a given size would cause. The one number worth treating cautiously is "Total FX Exposure": it's the sum of the absolute values of the transaction and translation impacts, which is a magnitude indicator for how much is in play, not a dollar amount you'd ever actually realize, since the two exposures can offset each other in practice (a weaker foreign currency can hurt cost of goods while helping the translated asset value, or vice versa depending on your net position).

How this is calculated
Worked example, using the default values
- Identify Input Parameters4 parametersForeign Currency Revenue = 1000000, Foreign Currency Costs = 600000, Foreign Currency Assets = 5000000, Foreign Currency Liabilities = 2000000 = 8 input(s) provided
- Calculate Rate ChangeRate Change = (rateChange / originalRate) * 100-4.55 = -4.55%
- Calculate Revenue FX ImpactRevenue FX Impact = revenueAtCurrent - revenueAtOriginal-50000 = $-50,000
- Calculate Cost FX ImpactCost FX Impact = costsAtCurrent - costsAtOriginal-30000 = $-30,000

Frequently Asked Questions
Why is Total FX Exposure not simply the sum of my transaction and translation impacts?
The calculator adds the absolute values of the Net Transaction Impact and Translation Gain/Loss rather than netting them, because a currency move can hurt one exposure while helping the other — a weaker foreign currency can shrink foreign-currency revenue in home-currency terms while also shrinking foreign-currency liabilities you carry. Total FX Exposure is meant as a magnitude indicator for how much value is currency-sensitive, not a dollar amount you'd ever actually collect or pay.
What's the difference between Revenue FX Impact and Budget Variance?
Revenue FX Impact compares foreign revenue converted at the Original Exchange Rate against the same revenue converted at the Current Exchange Rate, isolating pure currency movement since the position was established. Budget Variance instead compares revenue at the Current Exchange Rate against revenue at the Budget Exchange Rate you planned around, showing how far actual results are diverging from what was baked into the budget.
How does the Sensitivity Shock (%) work?
It applies one additional percentage move on top of the Current Exchange Rate — stressedRate equals current rate times (1 plus the shock percent) — then recomputes profit on foreign revenue and costs at that stressed rate and compares it to profit at the current rate. A positive shock strengthens the foreign currency further and a negative one weakens it further, showing how much more profit swing a plausible next move could cause.
Why might Cost FX Impact show as a negative number?
Cost FX Impact is costs at the current rate minus costs at the original rate, so it turns negative whenever the current exchange rate is lower than the original rate — your foreign-currency costs now convert into fewer home-currency dollars than before. A negative value here represents a savings from currency movement, not a loss.
