<p>The <b>NPER</b> function is one of the financial functions. It is used to calculate the number of periods for an investment based on a specified interest rate and a constant payment schedule.</p>
<pstyle="text-indent: 50px;"><b><em>rate</em></b> is the interest rate.</p>
<pstyle="text-indent: 50px;"><b><em>pmt</em></b> is a payment amount.</p>
<pstyle="text-indent: 50px;"><b><em>pv</em></b> is the present value of the payments.</p>
<pstyle="text-indent: 50px;"><b><em>fv</em></b> is the future value of an investment. It is an optional argument. If it is omitted, the function will assume <b><em>fv</em></b> to be 0.</p>
<pstyle="text-indent: 50px;"><b><em>type</em></b> is the period when the payments are due. It is an optional argument. If it is set to 0 or omitted, the function will assume the payments to be due at the end of the period. If it is 1, the payments are due at the beginning of the period. </p>
<pclass="note"><b>Note:</b> cash paid out (such as deposits to savings) is represented by negative numbers; cash received (such as dividend checks) is represented by positive numbers.</p>
<p>The numeric values can be entered manually or included into the cells you make reference to.</p>
