Calculates a quoted price for an interest paying security, per 100 currency units par value.


PRICE(settlementdate; maturitydate; rate; yield; redemptionvalue; frequency; basis)

settlementdate: the settlement (purchase) date of the security.
maturitydate: the maturity (redemption) date of the security.
rate: the (annual) coupon rate of the security.
yield: the required annual rate of return (compounded at each interest payment).
redemptionvalue: the redemption value of the security, per 100 par value.
frequency: number of interest payments per year (1, 2 or 4).
basis: is the calendar system to use. Defaults to 0 if omitted.
0 - US method (NASD), 12 months of 30 days each
1 - Actual number of days in months, actual number of days in year
2 - Actual number of days in month, year has 360 days
3 - Actual number of days in month, year has 365 days
4 - European method, 12 months of 30 days each

This function calculates a quoted price for a security (the 'clean' price). The price actually paid (the 'dirty' price) is more, because it includes accrued interest.
PRICE returns:
present_value_of_coupon_payments + present_value_of_redemption_payment - accrued_coupon_interest.
See Derivation of Financial Formulas for a more detailed formula.


PRICE("2008-02-15"; "2010-11-15"; 5%; 7%; 100; 2; 0)

returns approximately 95.06.


  • This function calculates present values compounding the yield each coupon period, yet the yield is a return per annum.
  • Present values for partial periods may be regarded as estimated.
  • The price is calculated as at the date of settlement (when the money changes hands). The contract to buy the bond (the trade date) may predate that (for example by 3 days).
