**Formula for calculating interest in Recurring deposit? - formula to calculate recurring deposit interest**

If I were a one-time payment of $ xx.xx each year in the AA and the filing of the complainant to pay interest annually to strengthen how do I calculate the interest rate?

How to calculate interest on deposits paid (s)?

What is the formula for the calculation?

Sum + = P (P (n +1) * r/2400)

where P is the monthly payment, n is the number of months, r the interest rate

DIAL 800 # ask to speak to a representative. And it explains all ..... Easy for you.

Formula to calculate the current filing, I hope this helps ..

A (N) = A [C (N +1.1) + C (N +1.2) * R + C (N +1.3) * r ^ ...

..............................[ Equatio ... 1]

where

A (N) indicates the amount repayable at maturity n in the time period N =

a is the annual filing ($ 10,000)

r is the annual interest rate and

C (M, Y) is defined as m! / [(MJ)! * J].

Let me say that it is not a simple equation to solve without a computer, because it is a polynomial of high order terms in r are known. "

The solution I came with a package of mathematics is about 7.19%.

The mathematical symbol m, is called "m factorial. It is the product of numbers from m to 1 told Specifically, given by m * (m-1) * (m-2 )*....* 2, * 1 .

Faculty of zero (0!) Just 1 is by definition.

The terms C (M, Y) = m! / [(MJ)! J *] If the coefficients of the polynomial in "s".

For example, C (N +1.3) = (N +1 )!/[( N 1-3)! * 3!]

= (N +1) * (N) * (N-1) * (N-2) * (N-3 )...* 2 * 1 / [(... * 3 * 2 * 1]

= (N +1) * (N) * (N-1) / [3 * 2 * 1] for simplification.

Note: The formula is based on the observation that the trend is clear from the following derivation is based.

A (0) = a,

One (1) = a (1 + r)

A (2) = (a (1 + r) + a) (1 + r) = a (2 + r) (1 + r) = a (2 3 ...

A (3) = [A (2) + a] (1 + r) = a (3 +3 r + r ^ 2) (1 + r) = a (...

A (4) = [A (3) + a] (1 + r) ... and so on.

Note: Formula-1 may be used only as a guide. Looking for professional advice from a qualified financial advisor before making any investment decision.

The exact formula for the total balance after years and assuming X amount has been deposited at the beginning of each of these years and that is:

A = X * (1 + r) * ((1 + r) ^ Y-1) / r

where r is the interest rate down. (The expressions of Kae and certain values are correct, but) the general formula.

The total amount is deposited with XY, so that the total interest paid:

I = A - XY

= X * (1 + r) * ((1 + r) ^ Y-1) / R - XY

*****

To use a concrete example, is deposited $ 1000 for the beginning of each year for 10 years at an interest rate of 5%. The balance and total interest paid as follows:

A 1000 = * (1.05) (1.05 ^ 10-1) / (.05) = $ 13,206.79

I = $ 13,206.79 - $ 10,000 = $ 3206.79

*****

To see the formula above, where it comes from, note that the total amount is now due to years prior to separation k X: X ^ k * u where u = (1 + r). Thus, the total is still this year and is the sum of a geometric series:

A = X * [+ uu ^ 2 + u ^ 3 +...+ n ^ Y] = X * [(u ^ (y +1)-u) / (U-1)]
