Independent tools · Updated for 2026/27
EV salary sacrifice calculators and employer tools
Sense-check employee and employer economics, grey fleet costs or provider-selection readiness before making a programme decision.
Choose the question you need to test
These tools separate employee take-home pay, company-car tax, employer National Insurance, grey fleet and provider-selection readiness so that each assumption can be checked rather than hidden in one headline saving.
They are guidance tools, not provider quotes or tax advice. Programme pricing, package inclusions, contracts, policy and individual circumstances remain decisive.
