Prorate one coupon across entered elapsed coupon-period days.
It makes the prices, cash flows, rates, time periods, weights, and model conventions explicit so you can inspect an entered scenario without hidden live-market assumptions.
At most 1,200 cash-flow periods or rows are supported. Payment periods must be whole and formula domains are validated explicitly.
International scope
No issuer, currency, exchange, settlement date, holiday calendar, day-count convention, tax rule, credit rating, yield curve, or contract term is selected automatically.
Decision boundary
Outputs are entered scenarios, not executable prices, credit opinions, duration hedges, call forecasts, risk limits, or recommendations.
Calculator-specific assumptions
The calculator uses the entered day-count fraction, not an automatically selected market convention.
