Useful next calculations
When to use this calculator
- Before accepting a pay change, bonus or contribution arrangement.
- When you want a simple take-home or conversion estimate before payroll or filing.
- When you need to convert between hourly, monthly and annual pay.
- When you want to compare two pay scenarios using the same assumptions.
A worked example
These are the example figures the calculator opens with.
| Input | Value |
|---|---|
| Annual Travel Allowance from Employer (R) | 60 000 |
| Business Kilometres Driven | 15 000 |
| Total Kilometres Driven | 25 000 |
| Vehicle Value (incl. VAT) (R) | 350 000 |
For those figures the calculator returns:
- SARS approved deduction: R60 000,00
- Taxable allowance: R0.00
- Additional tax on allowance: R0.00
- Net benefit of allowance: R60 000,00
- Business use: 60.00%
How to read your results
Taxable Allowance
Review this figure alongside gross income and the local tax rules that apply to you. It is a planning estimate, not a filing result.
Additional Tax on Allowance
Review this figure alongside gross income and the local tax rules that apply to you. It is a planning estimate, not a filing result.
Method & assumptions
For the tax year ending February 2027, the vehicle-cost schedule estimates deductible logbook business travel using fixed cost divided by total annual distance, plus scheduled fuel and maintenance per kilometre. Fixed cost is prorated for days used. Enter vehicle value including VAT and logbook distances; this assumes you incurred the fuel and maintenance costs and does not model multiple vehicles or employer-paid running costs.
The simplified R4.95/km option is only for circumstances where SARS permits it; selecting it does not establish eligibility. Deduction is capped at the travel allowance. The result estimates final annual incremental tax, not PAYE withholding. Employers usually include 80% of an allowance for PAYE, or 20% when reasonably satisfied that at least 80% use is business. Keep a compliant logbook and verify your permitted method.

Annual incremental tax includes the primary rebate and the additional age-65 and age-75 rebates for the 2027 tax year. Other credits and deductions are not modeled.
Common mistakes
- Using an assumption that is not supported by a current local quote, bill, statement or official source.
- Treating a generic estimate as a lender, provider, payroll or tax authority decision.
- Mixing monthly and annual inputs without converting them consistently.
- Testing only one scenario instead of checking how a cautious assumption changes the result.
What to do next
- Run a second scenario with a cautious assumption so you can see the downside clearly.
- Compare the result with the related calculators below before making a decision.
- Check current local rules, eligibility and provider terms before applying or committing money.
- Keep a record of the assumptions so you can update the estimate when a quote, bill or pay figure changes.
