How this calculation works

This is an illustrative example, not a current tariff quote. No VAT has been added to the entered rates. Check whether your figures already include VAT to avoid counting it twice. A supplier’s bill may also include tariff changes, discounts, adjustments, Economy 7 rates or different rounding.
