Indicative rate currently used by calculator: R3.822 per eligible litre.

The calculator provides an indicative estimate only and does not constitute tax, legal or financial advice. Actual eligibility depends on applicable SARS rules, qualifying activities, evidence and the refund rate applicable during each claim period.

How the calculation works

Eligible litres = monthly diesel purchased × estimated eligible percentage.

Indicative monthly refund = eligible litres × indicative rate per eligible litre.

Indicative annual refund = indicative monthly refund × 12.

Both inputs are estimates. Establishing eligible litres in practice requires reconciliation of purchases, storage, dispensing and activity records, and the applicable rate must be confirmed for each claim period.
