Preference points & functionality calculator
Model the price and preference outcome before you commit to a number. Every input, formula and intermediate value is shown so the calculation can be checked line by line.
Confirm the formula against the tender document. Preference point systems, thresholds and specific goals differ per tender and change with amendments to South African procurement regulations. BidSphere applies the values you enter here — it does not determine the applicable law, and it never infers ownership or demographic characteristics. Specific-goal points must be entered from verified evidence (for example a valid B-BBEE certificate or sworn affidavit).
Configuration
Capped at 20 under the 80/20 system.
VAT exclusive
Formula applied
Ps = 80 × (1 − (Pt − Pmin) / Pmin)
Pt = comparative price of the bid under consideration (VAT inclusive) · Pmin = comparative price of the lowest acceptable tender · Total = Ps + specific-goal points (max 20).

Worked calculation — our bid
Pmin = R 39 215 000
Pt = R 44 735 000
Ps = 80 × (1 − (R 44 735 000 − R 39 215 000) ÷ R 39 215 000)
Ps = 68.74 · specific goals = 16 · total = 84.74 points
