EV Salary Sacrifice Calculator

Electric cars through salary sacrifice can cost half what you’d pay leasing privately — because you swap gross pay (taxed) for a lease (untaxed bar a small BIK).

How we calculated your result

Salary sacrifice EV schemes work by reducing your gross salary by the monthly lease amount. The mechanics:

  1. You save Income Tax + employee NI on the sacrificed amount (~28% for basic rate, ~42% for higher rate).
  2. You pay Benefit-in-Kind tax on the car — P11D × BIK rate × your Income Tax rate. For 2025/26 the BIK rate for EVs is just 3%.
  3. Net cost = gross lease − tax saving + BIK tax.

Most schemes (Octopus, Tusker, LoveElectric etc.) bundle in insurance, servicing, breakdown and tyres — so the true like-for-like comparison vs renting a car privately is normally even more favourable than this number suggests.

Official UK rules in simple English

HMRC’s rules for EV salary sacrifice:

  • BIK rate for pure EVs: 2% (2024/25), 3% (2025/26), 4% (2026/27), 5% (2027/28), 7% (2028/29), 9% (2029/30).
  • OpRA (Optional Remuneration Arrangements): most company-car benefits lost their tax break in 2017, but ULEVs (≤75g/km CO2) were specifically exempted — which is why EV sal sac still works.
  • Minimum Wage check: your post-sacrifice salary can’t take you below National Minimum Wage.
  • Lease length: typically 36–48 months, with mileage allowance built in.

Common pitfalls to watch out for

  • Sacrificing salary affects pension and mortgage

    Your gross salary drops on paper, which can reduce auto-enrolment pension contributions and what mortgage lenders will offer. Many schemes use ‘notional’ salary for benefits — check the employer’s policy.
  • Early termination charges can sting

    Leaving the job or being made redundant usually triggers an early-termination fee — often the remaining months of lease, or a fixed sum. Some schemes offer protection insurance, often worth taking.
  • BIK is rising every year

    The 2% rate that hooked everyone in 2024/25 is gone. By 2029/30 it’s 9% — still much better than a petrol car’s 30%+ BIK, but the gap narrows. Lock in 3-year leases now to fix the rate.
  • Not all employers offer schemes

    EV sal sac requires the employer to set up an arrangement with a provider. Many SMEs don’t bother. If yours doesn’t, you can ask — but it can take months to roll out.

Frequently asked questions

Can I sacrifice down to National Minimum Wage?
No. The post-sacrifice gross salary must remain at or above NMW for your hours. Higher earners aren’t affected; this mainly blocks part-timers and lower-paid full-timers from the most expensive cars.
What about hybrids?
Plug-in hybrids (PHEVs) have BIK rates based on electric range — 8–14% for cars with 30–69 mile range. Much less attractive than pure EVs. Mild hybrids (no plug) are treated as petrols.
Can I keep the car at end of lease?
Usually not directly — but most schemes let you buy at fair market value at the end. Some employers run novated leases that work differently. Check the small print.
