Calculate the advance and its recovery
From the contract price and the advance rate, see the advance, its cap for your announcement date and what each progress payment recovers. The advance guarantee is released as the advance is recovered, and the 2025 balance update is included. No sign-up.
Advance and recovery plan
Enter amounts excluding VAT. The advance rate is written in article 13 of your contract; the recovery rate follows from it.

How the advance and its recovery are worked out
The advance is paid on the contractor's written request after the site handover and the approval of the work programme, against a guarantee of the same amount. It is recovered from each later progress payment at half as much again as the advance rate.
Advance = first contract price × advance rate
Most on a late request = (first contract price − work done) × advance rate
Recovery rate = advance rate × 1.5
Recovery = payment amount × recovery rate (at most the balance left)
13.11 difference = balance × (Pn − 1)
Amounts are rounded half up to the kuruş. The recovery rate is not rounded: 49.995% for a 33.33% advance. Pn − 1 keeps twelve places; below one there is no update.
Rules applied
- The cap and 01.09.2025
- The advance cannot exceed one third of the contract price. For tenders announced or invited in writing from 01.09.2025 the cap is 30%; earlier tenders keep the rules in force on their announcement date (Works Standard Contract 13.2, footnote 15; Works Tender Implementing Regulation, provisional art. 34).
- Late request
- If the advance is asked for later, or in parts, the amount given when asked cannot exceed the contract price of the work left times the advance rate (13.4). The recovery rate still follows the contract's advance rate.
- Recovery rate and base
- The recovery rate is the advance rate plus 50%: 30% for a 20% advance (13.9.1). It applies to each progress payment's amount at contract prices after the advance was paid; price adjustment and VAT stay out (13.9.2).
- Advance guarantee
- A guarantee equal to the advance is taken, valid until the recovery ends by the work programme. Each progress payment releases as much of it as is recovered (13.2, 13.9.3).
- Last provisional payment and liquidation
- Any balance left comes off the last provisional payment in full, whatever the rate; if the payment cannot cover it, the contractor pays the difference in cash within thirty days, otherwise the guarantee is called (13.9.4). If the work is liquidated, the balance is paid within thirty days of the liquidation acceptance (13.9.5).
- Balance update (13.11)
- In price-adjusted contracts for tenders announced from 01.09.2025, a balance the administration takes at once under 13.8, or repaid under 13.9.5, is updated by Pn. Pn uses the indices of the month the administration established the case (13.8) or of the liquidation acceptance date (13.9.5). Below one there is no update.
What this tool does not calculate
It does not cover interest on advances, advances in service contracts, or advances paid in several instalments. It does not work out Pn; you enter it. It does not check whether a payment can bear the recovery after its other deductions.
