Key Takeaways
- Appreciation = currency increases in value. Depreciation = decrease.
- Formula: Rate = ((New − Old) / Old) × 100
- Direct quotation (e.g., EUR/USD): base per quote. Indirect: quote per base.
- Appreciation makes imports cheaper, exports more expensive. Depreciation does the opposite.

How It Works
Exchange rates express the value of one currency in terms of another. When the rate increases (e.g., EUR/USD from 1.10 to 1.15), the base currency (EUR) has appreciated. The formula measures the percentage change. For multi-year periods, we annualize the rate for comparison.
Formulas
Rate = ((New − Old) / Old) × 100
Annualized = (1 + |r|/100)^(1/n) − 1, n = years
Import/Export impact = Amount × (New − Old) / Old

Frequently Asked Questions
What is currency appreciation?
Currency appreciation occurs when a currency increases in value relative to another. For example, if EUR/USD rises from 1.10 to 1.15, the euro has appreciated—it buys more dollars. Appreciation makes imports cheaper and exports more expensive for foreign buyers. Formula: Rate = ((New − Old) / Old) × 100.
What is currency depreciation?
Currency depreciation is when a currency loses value relative to another. If GBP/USD falls from 1.50 to 1.20, the pound has depreciated 20%. Depreciation makes imports more expensive and exports cheaper abroad. Emerging market currencies often depreciate during risk-off periods. The Turkish Lira lost 88% against the USD from 2017 to 2022.
What is the difference between real and nominal exchange rate?
The nominal exchange rate is the market rate (e.g., USD/JPY = 150). The real exchange rate adjusts for inflation: Real = Nominal × (Domestic CPI / Foreign CPI). A country with higher inflation may see its nominal rate appreciate while the real rate depreciates—eroding competitiveness. Central banks monitor real rates for trade balance.
What is purchasing power parity (PPP)?
PPP suggests exchange rates should equalize price levels across countries over time. If a basket costs $100 in the US and ¥15,000 in Japan, PPP implies USD/JPY ≈ 150. Deviations create arbitrage. The Big Mac Index and OECD PPP data track this. PPP is a long-term anchor; short-term rates are driven by interest differentials and capital flows.
What is a carry trade?
Carry trade profits from interest rate differentials: borrow in a low-yield currency (e.g., JPY), invest in a high-yield one (e.g., TRY). Currency moves can erase or amplify gains. When the funding currency appreciates (e.g., yen surge 2022), carry trades unwind—causing rapid depreciation in high-yield currencies. This calculator helps quantify those moves.
How does central bank intervention affect exchange rates?
Central banks intervene via interest rates, FX swaps, or direct market purchases. Rate hikes typically strengthen the currency; rate cuts weaken it. The Swiss National Bank's 2015 peg removal caused the Franc to surge 29% in minutes. Intervention can stabilize or destabilize—depending on credibility and market size.
