Quick guide
How to use this calculator
- Enter contractual cash flows, prices, rates, dates or day counts, and frequency assumptions.
- Use one consistent currency and the exact nominal/effective convention shown.
- Read the callable, curve, day-count, and duration limitations before interpreting the result.
Calculation method
Calculation method
Accrued interest = periodic coupon × elapsed days ÷ coupon-period days.
Iterative yields and curve results use bounded numerical solves and are marked approximate.
Worked example
Worked example
A 30 coupon halfway through a 180-day period has accrued interest 15.
Accrued interest = periodic coupon × elapsed days ÷ coupon-period days.
Supported inputs
Precision and limits
Visible input limits
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.
