Compare calculators
Both calculators run independently β change the inputs on either side to compare results.
Purchasing Power Parity Calculator
Computes the PPP-implied exchange rate between two countries from their relative price levels (typically CPI indices) and a base-period exchange rate, with an optional adjustment factor for measurement noise. Useful for assessing whether a currency is over- or under-valued versus its long-run equilibrium and for international productivity or income comparisons.
Currency Arbitrage Opportunity Calculator
Quantifies the potential profit from a triangular currency arbitrage across three currency pairs (USD/EUR, EUR/GBP, USD/GBP) by comparing the synthetic cross-rate against the direct rate, net of three transaction-cost legs. Useful for understanding the no-arbitrage condition between currency triangles and as a teaching tool β in practice, machine-driven liquidity providers close these arbitrages in milliseconds.
