Approximate 504 Loan Rate Calculators
Important Note: The above calculators are approximations because Excel does not properly compute the initial, abbreviated six-month coupon of the debenture. CSA will deliver the effective rate each month.
Effective interest rates are calculated by the Central Servicing Agent after receipt of debenture pricing provided by the Fiscal Agent every month. They are posted here as soon possible and should usually be available the day prior to funding, at the latest. Twenty and twenty five-year debentures are pooled and sold the first Thursday of the first full week of each month (beginning with and including Sunday). 10-year debentures are pooled and sold the first Thursday of the first full week of every other month (beginning with and including Sunday) starting with the January sale.
NOTE: Effective rates are posted on this site upon receipt from the CSA.
