Where each of these figures comes from
The calculator asks you for the percentages rather than supplying them, because each one is set by a rule, moved by an amendment, and then written into the particular tender. These three pieces carry the bands themselves, the exemptions and the dates, each against its source.
Money in a bid
The four sums, what each protects the buyer against, and the three dates a bid security comes back on.
EMD exemptions and the bid securing declaration
The bid-security band, who is exempt from furnishing it, and what the declaration commits a bidder to instead.
After you win
The performance-security bands, the share of each running bill withheld as retention, the due dates and the instruments.
What this does not do
It does not read your tender, judge your bid or tell you whether to submit one. It has no view on whether the figures you typed are the right ones. It only adds them up in the order the events happen.
Only one date on the schedule is arithmetic: the end of the contract period, if you gave a start date. Every other release runs off something the buyer does: the award, the receipt of the performance security, final acceptance. No calculator can date those.
Nothing is stored, nothing is sent and nothing is remembered between visits. There is no box asking who you are, because the answer is yours and not ours.
This is general information; confirm with the tender document and your adviser. Where the tender document and this page differ, the tender document governs: it is the thing you are bidding against.
