Settlement Efficiency Rate Calculator & AST Benchmark

Calculate your firm's Settlement Efficiency Rate (SER) by fail cause, benchmark against the UK AST ≥98% target, and see what improvement is needed by the July–September 2027 measurement window. Deterministic · Zero PII · Client-side.

Scope & reliance — All inputs are processed locally in your browser. No data is transmitted. Regulatory thresholds (AST ≥98%, CSDR Art.7) are static reference values verified as of May 2026 — confirm against current primary sources before relying on any output for compliance or commercial decisions.

Panel 01 — Settlement Data (Value Method)

🔒 All inputs are processed locally in your browser. No data is transmitted. Do not enter real personal data — use synthetic or anonymised inputs only.

Total value due to settle this period (€/£ millions) Denominator of SER — all instructions due for settlement on ISD.

Total value settled on intended settlement date (€/£ millions) Numerator — instructions that settled on ISD without carry-over or partial.

Or derive fails from counts in Panel 02 — both methods work independently

Panel 02 — Fail Cause Breakdown (optional detail layer)

Enter fail counts by cause plus average fail value to derive total failed value and per-cause SER impact. Leave blank if using value totals in Panel 01 only.

Allocation / confirmation fails (count)

Securities unavailable / short position (count)

Cash / funding fails (count)

Technical / system fails (count)

Counterparty fails (count)

Other fails (count)

Average fail value (€k per fail) Used to convert fail counts to monetary fail value for per-cause SER breakdown.
