Tender points calculator: 80/20 and 90/10
Work out your tender score for price and specific goals under the 80/20 or 90/10 system, and how much dearer than the cheapest bid you can be and still win. Free.
The rules in short
- 80/20 for tenders up to R50 000 000 (all taxes included), 90/10 above. The tender documents say which applies.
- Points for price = 80 × (1 − (your price − lowest acceptable price) ÷ lowest acceptable price); 90 instead of 80 on 90/10. When the state sells or lets something, the highest price scores best.
- Specific goals add up to 20 (or 10) points, as set in the tender (SBD 6.1). The total is rounded to two decimals; a tie goes to the higher specific-goal score.
