Factors affecting your result
Annual coupon, flat yield and full-year periods; accrued interest, credit risk and callable features are excluded.
Changing face value changes the scenario being evaluated. Adjust one input at a time when comparing results, keep a copy of the assumptions, and compare values using the same unit and period. A precise arithmetic result does not make an uncertain assumption precise.
