When using the Actual/360 method, the annual interest rate is divided by 360 to get the daily interest rate and then multiplied by the days in the month. This creates a larger dollar amount in interest payments because dividing the annual rate by 360 creates a larger daily rate then dividing it by 365.

Most banks use the actual/360 method because it helps standardize daily interest rates throughout the year. Another reason they prefer to calculate over 360 days instead of 365 is that the daily interest rate is slightly higher.May 9, 2022

How to calculate interest on a promissory note?

Promissory notes frequently contain language providing that interest will be computed by multiplying the stated interest rate by 365 and dividing that number by 360.

The reasoning behind this method goes to the bank's attempts to standardize interest rates on a 30-day month, while taking into account the 365-day calendar year. The 365/360 method has been recognized for quite some time by the Illinois Department of Financial & Professional Regulation, as well as courts throughout Illinois, as an appropriate means of calculating interest.

Does the 365/360 method violate the Illinois Consumer Fraud Act?

In raising defenses to mortgage foreclosure cases and in plaintiff's class action cases, however, borrowers are claiming that the 365/360 method violates the Illinois Interest Act because certain promissory notes refer to interest being calculated either "per annum" or "annually." In some cases, these parties are maintaining that the method also violates the Illinois Consumer Fraud Act and provides evidence of fraud. Furthermore, borrowers are contending that the Illinois Interest Act requires lenders to use a calendar year to compute interest whenever the word "year" (or a comparable term) is used in a loan document. With respect to damages, some borrowers have also argued that the Illinois Interest Act allows them to recover twice the amount of the unauthorized interest that was charged.

What is the difference between a tropical and a sidereal year?

The sidereal year is relative to the stars and mostly important to astronomers. The tropical year considers motion around the sun, intersection of the equator and the ecliptic (path of earth’s orbit), the precession of the tilt in the earth’s axis), the elliptical orbit of the earth (resulting in non-constant daily motion), etc. Ultimately, it is the measure of year that fixes the position of the seasons and the year our calendars try to approximate. The average Gregorian year (365.2425 solar days) is close to but a bit longer than the tropical year, currently 365.24219 solar days and slowly shortening. Eventually, we will need to eliminate a leap day to compensate.

How many days does it take for the Earth to rotate around the Sun?

You should differentiate between calendar years, which are “administrative” units and agreed by convention, and the solar year which represents the time it actually takes for the earth to make one full rotation around the sun. The period of time required for the earth to make one complete revolution around the sun, being 365 days, 5 hours, 48 minutes and 45.51 seconds. You can see that it is not exactly 0.25 of a day.

What is the difference between a day and a year?

The terms “day” and “year” have multiple subtle meanings. The day is one rotation of the earth, but do you measure with respect to the sun or the fixed stars. Because the earth also orbits the sun, there is some daily angular motion in orbit which makes the two different. But the big ball of light in the sky is kind of important, so we define time as subdivisions of the mean solar day, not the sidereal day (based on fixed stars). The earth’s rotation is only a so-so clock. We now define time via an atomic clock and declare leap second to fix the small cumulative error between the mean solar da

How many days are in a year?

Wikipedia says that a year has 365.242374 days [1]. This means that 1 out of 4 years being a leap year is actually overcompensating. That's why the rule is that every 4th year is a leap year -- unless it's divisible by 100 but not 400. This means there are 97 leap years* every 400 years, which adds an average of 97/400=.2425 days to the standard 365-day year. According to Mike Greenfield in one of the comments on this answer, the remaining difference is basically ignored because it's a tolerable error.

If each year is 365.24 days, meaning we "lose" 11 minutes every year (factoring leap years), why isn't noon in the middle of the night after 60 years?

How many seconds are there in a day?

Everyday we reset our clocks to match the days, kind of. A day is (on the average) 86,400 seconds. Not every day is exactly 86,400 seconds, some are a bit longer, some are a bit shorter. But on the average, for a year the days are 86,400 seconds. So noon doesn’t shift, much.
