To calculate the payments of a loan in Excel, you can use a simple formula PMT which calculates the amount of the loan or the loan based on constant payments and a constant periodic rate of interest.

 PMT(rate, nper, pv, fv, type)

Rate -  is the interest rate for the loan
Nper -  is the total number of payments for the loan
Pv -  is the present value, or the total amount that a series of future payments is worth now; also known as the principal
Fv - is the future value, or a cash balance you want to attain after the last payment is made.

If fv is omitted, it is assumed to be 0 (zero), that is, the future value of a loan is 0. Type - is the number 0 (zero) or 1 and indicates when payments are due.

You can used to PPMT function - Returns the payment on the principal for a given period for an investment based on periodic, constant payments and a constant interest rate.

PPMT(rate, per, nper, pv, [fv], [type])

Per - Required. Specifies the period and must be in the range 1 to nper.
Nper - Required. The total number of payment periods in an annuity.
Pv - Required. The present value — the total amount that a series of future payments is worth now.

= B2 & B3   or   = CONCATENATE (B5, B6)

How to Calculate a Standard Deviation in Excel?

How to calculate  a Standard Deviation in Excel?

---

In statistics and probability theory, standard deviation (represented by the symbol sigma) shows how much variation or dispersion exists from the average (mean), or expected value (read more on wikipedia).

http://en.wikipedia.org/wiki/Standard_deviation

---

The standard deviation is calculated as the square root of the variance. Thus, the designation of the variance can be regarded as an intermediate step to calculate the standard deviation.

In excel there is a function that directly from the data (sample) calculates standard deviation.

Excel function:
STDEV ( number1, number2, ... ) 

Number1, number2, ... are 1 to 255 arguments corresponding to a sample of the population.

Instead of arguments separated by semicolons, you can use a single array or a reference to an array. The following figure shows the calculation in excel in two ways.
