<p>The <b>IPMT</b> function is one of the financial functions. It is used to calculate the interest payment 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 for the investment.</p>
<pstyle="text-indent: 50px;"><b><em>per</em></b> is the period you want to find the interest payment for. The value must be from <b><em>1</em></b> to <b><em>nper</em></b>.</p>
<pstyle="text-indent: 50px;"><b><em>nper</em></b> is a number of payments.</p>
<pstyle="text-indent: 50px;"><b><em>pv</em></b> is a present value of the payments.</p>
<pstyle="text-indent: 50px;"><b><em>fv</em></b> is a future value (i.e. a cash balance remaining after the last payment is made). 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 a 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 <b><em>type</em></b> is set to 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. Units for <em>rate</em> and <em>nper</em> must be consistent: use N%/12 for <em>rate</em> and N*12 for <em>nper</em> in case of monthly payments, N%/4 for <em>rate</em> and N*4 for <em>nper</em> in case of quarterly payments, N% for <em>rate</em> and N for <em>nper</em> in case of annual payments.</p>
<p>The numeric values can be entered manually or included into the cell you make reference to.</p>
