- Actual-over-365 (US Rule). The actual-over-365 method counts the number of days in the first period (between the loan date and the first payment due date), and then computes the first period interest charge by applying 1/365th of the annual rate for each day in the first period. Interest is accrued using the U.S. Rule. For each subsequent month, the actual number of days is counted between each payment due date and the next, and the interest charge for the period is computed by applying 1/365th of the annual rate for each day within the period (28, 29, 30 or 31 days).

How to Calculate Menstrual Cycle Length To calculate menstrual cycle length, you count the number of days from day one of your period (CD 1) up to, and including, the day before the next period starts. The count does not include the first day of the next menstrual period, because that's Cycle Day 1 of the next cycle. Your average cycle length displays. 2  Each time you track your next period, your cycle length is updated! 3  Use My History/Quick History, or the Menstrual Cycle Chart, to see your average, shortest and longest menstrual cycle length.

How to Compute the Holding Period Return on an Investment Add the cash flows to the holding period's ending investment value. In the example, if stock ABC rose to $125 per share, add $125 plus $4 to calculate a total value of $129 per share. Divide this figure by the investment's value at the beginning of the holding period. In the example, if you purchased stock ABC for $50, divide $129 by $50 to calculates a multiplier of 2.58. Subtract one from the multiplier to calculates the HPR in decimal format. In the example, 2.58 minus 1 calculates an HPR of 1.58. Multiply this figure by 100 to convert it to percent format. In the example, 1.58 times 100 converts the decimal format to a 158 percent return on investment during the holding period.

Weeks? Months? Trimesters? Lunar months? Days? How does the pregnancy due date calculator work? Your due date is determined by a simple calculation – Add 280 days (40 weeks) to the first day of your last menstrual period (assuming a 28-day cycle). Note that your menstrual period and ovulation are counted as the first two weeks of pregnancy. If you deliver on your due date, your baby is actually only 38 weeks old, not 40. Need to know : On average only 5% of births take place exactly on the estimated due date.

Given the orbital radius of a satellite, how is the orbital period calculated? For a circular orbit orbital velocity is constant at √(G/r)(M+m) So for orbital period: you know r (also constant), so calculate the length of the orbit (circumference, assuming it's a circle) and period is just length / velocity. Notice for a given primary the only thing that really matters is r.

How does the length of the pendulum effect the period. Physics question.Help!!!? Best Answer: Your formula for the complete cycle period of a SIMPLE pendulum is: T = 2*Pi*sqrt(L/g) L is the length, g is the local gravitational field. sqrt() indicates the square root function. And Pi is the famous 3.14159 number, the ratio of circumference to diameter of any circle. If you quadruple the length of a simple pendulum, you will double the period of swing. In order to triple the period, you would need to increase the pendulum's length 9-fold. I use and emphasize the word simple, because the contrary is a physical pendulum.

Period of a Function We may also calculate the period using the formula derived from the basic sine and cosine equations. The period for function y = A sin( B x - c ) and y = A cos( B x - c ) is $\frac{2 \pi}{B}$ radians. The reciprocal of period of a function is equal to its frequency. Frequency is defined as the number of cycles completed in one second. If the period of a function is denoted by P and f be its frequency, then -.

AGENCY: Use the same interest rate formula and adjust the time period. Determine the period of time to properly recognize interest expense. If you need to calculate three months of interest expense, divide the 12 months by the number of months in the desired period. For example, t = 3/12 or 0.25. If the principal is $10,000 and the interest rate is 12 percent (0.12), the calculation would be Interest = $10,000 x 0.12 x 0.25 or $300.
