Example of the PVIF Using the formula for calculating the PVIF, the calculation would be $10,000 / (1 + . 05) ^ 5. The resulting PVIF figure from the calculation is $7,835.26. The present value of the future sum is then determined by subtracting the PVIF figure from the total future sum to be received.

How do you calculate the present value factor?
PV = FV * [ 1 / (1+r)n ]
- PV = FV * [ 1 / (1+r)n ]
- PV = 5500 * [ 1 / (1+8%) 2 ]
- PV = Rs. 4715.
How do you calculate the present value of an annuity interest factor?
The initial deposit earns interest at the interest rate (r), which perfectly finances a series of (n) consecutive withdrawals and may be written as the following formula: PVIFA = (1 – (1 + r)^-n) / r.
How do you calculate present value example?
Example of Present Value
- Using the present value formula, the calculation is $2,200 / (1 +.
- PV = $2,135.92, or the minimum amount that you would need to be paid today to have $2,200 one year from now.
- Alternatively, you could calculate the future value of the $2,000 today in a year’s time: 2,000 x 1.03 = $2,060.
What formula is used to calculate KF form factor?
c) kf= effective value/maximum value.
How do you calculate present value factor in Excel?
Again, the formula for calculating PV in excel is =PV(rate, nper, pmt, [fv], [type]). The inputs for the present value (PV) formula in excel includes the following: RATE = Interest rate per period. NPER = Number of payment periods.
Why do we calculate form factor?
It identifies the ratio of the direct current of equal power relative to the given alternating current. The former can also be defined as the direct current that will produce equivalent heat.
What is the value of form factor answer?
4.6
| WAVEFORM | MAX. VALUE | FORM FACTOR |
|---|---|---|
| SINUSOIDAL WAVE | A m | A m 2 2 A m π = 1.11 |
| SQUARE WAVE | A m | A m A m = 1 |
| TRIANGULAR WAVE | A m | A m 3 A m 2 = 2 3 |
| HALF-WAVE RECTIFIED WAVE | A m | A m 2 A m π = π 2 |
What is form factor in alternator?
Definition: The ratio of the root mean square value to the average value of an alternating quantity (current or voltage) is called Form Factor. The average of all the instantaneous values of current and voltage over one complete cycle is known as the average value of the alternating quantities.
How do you calculate the present value of a loan?
How to calculate present value
- Determine the future value. In our example let’s make it $100 .
- Determine a periodic rate of interest. Let’s say 8% .
- Determine the number of periods. Let’s make it 2 years .
- Divide the future value by (1+rate of interest)^periods.
What is the formula for present value of ordinary annuity?
The formula for determining the present value of an annuity is PV = dollar amount of an individual annuity payment multiplied by P = PMT * [1 – [ (1 / 1+r)^n] / r] where: P = Present value of your annuity stream. PMT = Dollar amount of each payment. r = Discount or interest rate.
What is the ratio of form factor?
The Form factor is defined as the ratio of the RMS value to the average value of an alternating quantity. Crest Factor ‘or’ Peak Factor is defined as the ratio of the maximum value to the R.M.S value of an alternating quantity.
What form factor means?
Form factor is a hardware design aspect that defines and prescribes the size, shape, and other physical specifications of components, particularly in electronics. A form factor may represent a broad class of similarly sized components, or it may prescribe a specific standard.
What does form factor tell?
What does this mean for motors and variable frequency drives? Well, the motor still draws magnetising current and therefore has a power factor less than 1.0, as stated on the rating plate.
How will you calculate its form factor and peak factor define both these terms and the parameters on which these depend on?
Im and Em are the maximum value of the current and the voltage respectively, and Ir.m.s and Er.m.s are the roots mean square value of the alternating current and the voltage respectively. For the current varying sinusoidally, the peak factor is given as: The value of Peak Factor is 1.4142.
What is form factor and peak factor explain?
The ratio of rms value to average value of an ac quantity is called form factor. Form Factor = RMS value/ Average value. The ratio of maximum value to the RMS value of an ac quantity is called as peak factor. Peak Factor = Maximum Value/RMS value.
How do you find form factor and peak factor?
The form factor of an alternating current waveform is the ratio of the RMS value to the average value. The peak factor is the peak amplitude of the waveform divided by the RMS value of the waveform.
