Formula used
1. Working days per year
Working Days = Workdays per Week × Weeks per Year
2. Commute days per year
Commute Days = max(Working Days − (Remote Days per Month × 12), 0)
3. Pay-as-you-go annual cost
PAYG Cost = One-way Fare × Trips per Day × Commute Days
4. Pass-based annual cost
Monthly Pass Annual = Monthly Pass × 12
Annual Pass Annual = Annual Pass Cost
5. Gross annual transport cost
Gross Cost = Selected Base Cost + (Extra Monthly Fees × 12)
6. Employer subsidy
Monthly Subsidy = min((Gross Annual ÷ 12) × Subsidy %, Monthly Cap)
7. Cost after subsidy
After Subsidy = Gross Annual Cost − Annual Employer Subsidy
8. Tax relief
Tax Relief = After Subsidy × Tax Relief %
9. Net annual employee cost
Net Annual Cost = After Subsidy − Tax Relief
10. Savings versus car
Savings vs Car = Alternative Car Daily Cost × Commute Days − Net Annual Cost

FAQs
1. What does this calculator estimate?
It estimates gross commuting cost, employer subsidy, tax relief, net employee cost, cost per commute day, and savings compared with driving.
2. When should I use the cheapest option mode?
Use it when you want the tool to compare pay-as-you-go, monthly pass, and annual pass costs automatically and choose the lowest base commute option.
3. Do remote days affect all payment models?
Remote days directly reduce pay-as-you-go usage. Fixed passes still help comparisons, but their listed price remains unchanged because they are usually prepaid.
4. Why include employer subsidy and tax relief separately?
They reduce cost in different ways. Subsidy is direct employer support, while tax relief estimates savings created by pre-tax or deductible benefit treatment.
5. What should I enter for alternative car daily cost?
Include fuel, tolls, parking, wear, and daily driving expenses. That comparison helps show whether public transport provides a financial benefit.
6. Can this calculator handle annual fare increases?
Yes. The growth field projects a simple next-year net cost using your current result and the expected annual fare increase percentage.
7. Is this tool suitable for employee benefits planning?
Yes. It is useful for HR teams, payroll planners, and employees evaluating commuting benefits, hybrid policies, subsidy caps, and pre-tax support.
8. Does this replace payroll or tax advice?
No. It is a planning calculator. Final tax handling, subsidy rules, and reimbursement treatment should be checked against local regulations and company policy.
