course, for this example it is assumed that there will be no deposits nor withdrawals within this timeframe. 6 divided 2. You can use the NPER function to get the number of payment periods for a loan, given the amount, the interest rate, and periodic payment amount. This tells us that the certificate of deposit will mature in 3 years. The Excel NPER function is a financial function that returns the number of periods for loan or investment. Where FV is the future value, PV is the present value, r is the periodic compound interest rate and n is the total number of periods.

monthly rate. In the example shown C9 contains this formula: = NPER ( C6 , - C7 , - C4 , C5 , 0 ) The formula for solving for number of periods may also be referred to as solving for n, solving for term, or solving for time. The exact formula that we can use depends on whether we are dealing with simple interest or compound interest.

This result can be found in the "middle section" of the table matched with the rate to find the number of periods, n.

Find out the number of periods in both financial instruments. Since the interest rate is in years, we get t in years too.
value of money. We can use the expression for future value in case of simple interest to arrive at simple interest rate equation: $$ \text{FV}\ =\ \text{PV}\times(\text{1}+\text{i}\times \text{t}) $$, $$ \frac{\text{FV}}{\text{PV}}\ =\frac{\ \text{PV}}{\text{PV}}\times(\text{1}+\text{i}\times \text{t})=\text{1}+\text{i}\times \text{t} $$, $$ \frac{\text{FV}}{\text{PV}}-\text{1}\ =\text{i}\times \text{t} $$, $$ \frac{\text{FV}\ -\ \text{PV}}{\text{PV}}=\text{i}\times \text{t} $$, $$ \text{t}\ =\ \frac{\text{FV}\ -\ \text{PV}}{\text{PV}\times \text{i}} $$. The number of periods annuity formula PV can be used for example to determine the number of annuity payments required to clear the balance on a loan account. n = LN (Pmt / (Pmt - PV x i)) / LN(1 + i) n = LN (6000 / (6000 - 50000 x 6%)) / LN(1 + 6%) n = 11.90 periods The same answer can be obtained using the Excel NPER function as follows: n = NPER(i,pmt,PV,FV,type) n = NPER(6%,-6000,50000,,) n = 11.90 periods The number of periods annuity formula PV is one of many annuity formulas used in time value of money calculations, discover … This site was designed for educational purposes. From here, both sides of this formula can be divided by ln(1+r) which will equal the formula If the interest rate on the loan is 6%, the number of periods (n) it would take to clear the loan balance is given as follows: The same answer can be obtained using the Excel NPER function as follows: The number of periods annuity formula PV is one of many annuity formulas used in time value of money calculations, discover another at the link below.

Let's connect.

As previously stated in the prior section, the number of periods and the periodic rate should match one another. This number of periods annuity formula PV calculates the number of periods required for an annuity payment (Pmt) made at the end of each period to produce a present value (PV) when a discount rate (i) is applied. He has been the CFO or controller of both small and medium sized companies and has run small businesses of his own. shown at the top of this page. To calculate the number of periods needed for an annuity to reach a given future value, you can use the NPER function.

In case of compound interest, number of periods can be derived using the basic time value of money equation: $$ \text{FV}=\text{PV}\times{(\text{1}+\text{r})}^\text{n} $$. Step 3: rearranging the above equation using quotient and power rules of logarithm: $$ \text{log}\ (\text{FV})\ -\ \text{log}\ (\text{PV})=\text{n}\times \text{log}\ (\text{1}+\text{r}) $$. The formula to calculate the number of periods based on present value and future value can be found by first looking at the Email: admin@double-entry-bookkeeping.com.
