BER combines direct APIs, public website and JSON quote capture, user-submitted rates and indicative pricing rules to provide useful FX comparisons across providers.
A practical comparison methodology
Foreign exchange pricing can change with the currency pair, transfer amount, customer type and payment method. Some providers publish a complete live quote; others expose only part of the cost.
Best Exchange Rates combines directly observed pricing, market benchmarks and clearly defined estimate rules to make those options easier to compare. The result is an informed comparison—not a guaranteed executable quote.
Where the data comes from
Coverage varies by provider and corridor, so a comparison can use one or more of these sources.
Where a provider supplies machine-readable pricing, BER uses the returned customer rate and available fee data as a direct source.
BER records pricing exposed through public calculators, quote forms or structured website data.
When complete pricing is not publicly observable, BER may estimate it from provider behaviour, fee rules, amount bands and supporting rate submissions.
The common reference point
The mid-market rate is the reference point used to measure provider pricing. When BER observes a provider quote, it also records the market rate for that time.
This allows BER to assess the provider’s pricing relative to the market rather than comparing quotes captured at different market levels. An observed relationship may later be restated against a newer benchmark so the comparison remains timely.
Restating does not turn an observation into a live provider quote. It produces a current indicative comparison based on the pricing relationship BER observed.
Understanding the result
A rate or fee collected from an API, structured feed or public provider quote flow for a defined scenario.
An observed pricing relationship applied to a more current market reference to improve timing consistency.
A modelled rate or fee based on available observations, amount ranges, fee structures and other market inputs.
Unless BER explicitly states otherwise, non-API comparison pricing should be treated as indicative.
Making unlike quotes comparable
Provider pricing often changes by transfer size. BER groups observations into amount ranges and may use the nearest relevant range when an exact observation is unavailable.
A strong-looking exchange rate can be offset by fixed, variable or delivery fees. BER aims to compare the effective result, not just the headline rate.
Sources update on different schedules. Benchmarking and restating help reduce timing differences, while provider-site changes can temporarily reduce direct coverage.
Pricing transparency varies across markets. The source and confidence available for one provider or currency route may differ from another.
Supporting evidence
Selected BER pages allow users to submit a rate received from their provider. These observations can help validate captured pricing, refine amount-range assumptions and identify changes or anomalies.
Submissions are intermittent and are not treated as complete market coverage. They support calibration and quality checks alongside other sources.
Important limitations
The rate available to an individual customer can differ because of factors BER cannot fully observe before a provider produces a live quote.
Always confirm the final exchange rate, fees, recipient amount and eligibility directly with the provider before transacting.
