Financial comparisons become easier when the formula is transparent. Brexit Calculator turns the displayed inputs into a repeatable estimate that you can recalculate as rates, prices, or other assumptions change. On this page, it is intended to model a trade-cost scenario from annual trade value, tariff/duty, compliance cost, and FX impact.

What this calculator does

Brexit Calculator is intended to model a trade-cost scenario from annual trade value, tariff/duty, compliance cost, and FX impact. Its visible inputs are Currency, Annual UK/EU trade value, Tariff or extra duty rate, Admin/compliance cost rate, GBP/EUR exchange-rate impact. The article follows those fields and the calculation that is actually available on this page; it does not silently add live market feeds, tax tables, legal eligibility tests, or other variables that are not present in the tool.

How to use it

Enter Currency, Annual UK/EU trade value, Tariff or extra duty rate, Admin/compliance cost rate, GBP/EUR exchange-rate impact. Use the units and percentage scale shown beside each field, and keep values on the same time basis when the formula compares income, rates, prices, balances, or work hours.

How the calculation works

The intended scenario combines annual trade value with extra tariff/duty, administrative cost, and exchange-rate impact. The visible fields are not correctly connected to the current calculation, so the default £0 result should not be read as a quantified Brexit cost.

Example

With the current demonstration values (Annual UK/EU trade value = 100,000; Tariff or extra duty rate = 5; Admin/compliance cost rate = 2; GBP/EUR exchange-rate impact = 0), the page shows £0 for scenario-adjusted value. Because that conflicts with the nonzero values already visible on the form, treat this example as evidence of the limitation—not as a valid financial result.

How to interpret the result

Interpret the output according to the metric being calculated: a ratio, score, exchange relationship, chart level, safety incidence rate, or cost comparison. It is best for consistent measurement and scenario comparison, not for turning one metric into a complete business or investment decision.

Limitations and notes

The current default result is £0 for a nonzero trade value, so it is only an incomplete scenario page in its present state. This tool uses the data you enter and does not independently validate the underlying source, legal classification, market quote, accounting treatment, or workplace recordability decision. A clean calculation can still be wrong if the source data or definition is wrong.
