About Me

**Net present values, calculating**

If you know the interest rate and the corresponding annual - do my assignments for me , monthly or daily interest, you can calculate the associated capital (better the associated capital value) by dividing the interest received by the interest rate and multiplying the value obtained in this way by 100.

This leads to the following formula when the interest rates are known for n years:

K= Z⋅ 100 / p ⋅ n

**Example:**

With an interest rate of 4%, you get € 21.50 interest after one year. How big was the invested capital?

The capital was ( € 21.50 / 4 ⋅ 1 ) ⋅ 100 = € 537.50

The following formulas apply to the calculation of capital values after a period of m months or t days:

K= Zm⋅ 100 ⋅ 12 / p ⋅ m (Monthly interest and interest rate are known.)

K= Zt⋅ 100 ⋅ 360 / p ⋅ t (Daily interest and interest rate are known.)

Most banks calculate with 30 days for a month and 360 days for a year.

Capital invested in a savings account earns interest at a certain rate.

**Time spans, calculation**

If you know the capital - algebra homework help , the interest rate and the corresponding annual, monthly or daily interest, you can calculate the periods of time (number of years, months or days) for which the interest accrues.

Depending on which values are known, the formula for annual - do my excel homework , monthly or daily interest is then used.

This leads to the following formula if the interest for n years is known:

Annual interest , interest rate and net present value are known:

n = Z⋅ 100 / p ⋅ K

Monthly interest, interest rate and capital value are known:

m = Z⋅ 100 ⋅ 12 / p ⋅ K

Daily interest rates , interest rate and capital value are known:

t = Z⋅ 100 ⋅ 360 / p ⋅ K

In contrast to calculating interest rates, or capital values, time span calculations are of relatively little practical importance.

Capital invested in a savings account earns interest at a certain rate.
