How the CETES estimate works
CETES are discount securities. Their estimated yield is the difference between the purchase price and the MXN 10 face value paid at maturity. The selected annual rates below mirror the Spanish calculator; confirm current auction terms with Cetesdirecto before investing.
- The price estimate uses
P = 10 / (1 + rate × days / 360). - CETES are Mexican federal government securities; their backing is sovereign, not deposit insurance.
- The sample rates are reference inputs. Check the latest auction rate and terms before making a decision.
