How to read a comparison or estimate

A calculated result depends on the product terms and conventions entered into it. A displayed yield is an estimate under stated assumptions; it is not a guaranteed return or a substitute for the issuer’s current contract.

Start with the instrument and its terms

Mexican products can quote annual rates while paying, compounding or settling over a shorter period. Comparing two headline rates alone can hide differences in term length, minimum balance, maximum remunerated balance, liquidity, fees and eligibility. A useful comparison identifies which terms apply before estimating an amount.

For fixed-term deposits, use the day-count basis specified in the issuer’s contract or official product terms. A year may be represented with a 360-day or 365-day convention depending on the product and its documentation. The calculator should follow the applicable terms; choosing a generic basis can change the estimated interest.

CETES and the 360-day convention

CETES calculations use a 360-day year convention for the applicable annualized discount and yield calculations. This is a financial day-count convention, not a claim that the calendar year has only 360 days. For example, the convention scales the elapsed days within the formula using 360 in the denominator. The actual instrument’s days to maturity still come from its dates.

This distinction matters: a CETES calculation using 360 days and a fixed-term deposit using 365 days are not contradictory when each follows its own published terms. Check the specific instrument before comparing the resulting annualized figures or cash amounts.

Taxes, protection and limits

Tax outcomes and deposit protections depend on current Mexican law, the financial institution, product type and the holder’s circumstances. They can change. DondeRinde does not establish a reader’s personal tax position; confirm applicable rules with official sources and a qualified professional when needed. The sources page links to Mexican public institutions, and the Spanish edition contains the Mexico comparison tools.

For contract-specific details, read the issuer’s current disclosure and terms directly. See editorial standards and about DondeRinde. This methodology page addresses the Mexico financial desk only; a global editorial methodology has not yet been established.
