Formula Used
Average SOFR (%) + [Spread Adjustment (bps) ÷ 100]
Delay Days ÷ Day Count Basis
Effective Purchase Price × [Cost of Carry Rate ÷ 100] × Delay Fraction
Effective Purchase Price × [Cost of Carry Rate ÷ 100] ÷ Day Count Basis
Days between two business days before commencement and two business days before delayed settlement
The spread default and lookback concept reflect standard LSTA-style guidance for this calculation. :contentReference[oaicite:1]{index=1}

Frequently Asked Questions
1. What does this calculator estimate?
It estimates the carry cost for a delayed settlement using purchase price, average SOFR, spread adjustment, delay days, and the selected day count basis.
2. Why does the form ask for average SOFR instead of live rates?
This file is self-contained. It avoids external rate feeds, so you can enter the average SOFR already calculated for your relevant lookback period.
3. What is the default spread adjustment?
The form starts with 11.448 basis points. That is the commonly cited fixed adjustment for this LSTA-style convention.
4. How are delay days counted here?
The calculator uses the calendar-day difference between commencement and delayed settlement dates. It does not automatically exclude weekends or holidays from the delay period.
5. How are lookback dates determined?
The page subtracts two business days from each entered date. This is informational only and does not account for market holidays.
6. When should I use adjusted purchase price?
Use it when your internal settlement process requires a revised effective price. If left blank, the original purchase price is used automatically.
7. What does the chart show?
The chart plots cumulative carry across the delay period. It helps you see how the estimated charge grows each day.
8. Can I export the output?
Yes. The calculator exports a CSV summary and a PDF report, including the core inputs and results.
