<h1>PPMT Function</h1>
|
|
<p>The <b>PPMT</b> function is one of the <a href="../UsageInstructions/InsertFunction.htm#financial" onclick="onhyperlinkclick(this)">financial functions</a>. It is used to calculate the principal payment for an investment based on a specified interest rate and a constant payment schedule.</p>
|
|
<h3>Syntax</h3>
|
|
<p><b><em>PPMT(rate, per, nper, pv, [fv] ,[type])</em></b></p>
|
|
<p>The <b>PPMT</b> function has the following arguments:</p>
|
|
<table style="width: 40%">
|
|
<tr>
|
|
<th style="background-color: #f4f4f4" width="150ch"><b>Argument</b></th>
|
|
<th style="background-color: #f4f4f4"><b>Description</b></th>
|
|
</tr>
|
|
<tr>
|
|
<td><b><em>rate</em></b></td>
|
|
<td>The interest rate for the investment.</td>
|
|
</tr>
|
|
<tr>
|
|
<td><b><em>per</em></b></td>
|
|
<td>The period you want to find the principal payment for. The value must be from <b><em>1</em></b> to <b><em>nper</em></b>.</td>
|
|
</tr>
|
|
<tr>
|
|
<td><b><em>nper</em></b></td>
|
|
<td>The number of payments.</td>
|
|
</tr>
|
|
<tr>
|
|
<td><b><em>pv</em></b></td>
|
|
<td>The present value of the payments.</td>
|
|
</tr>
|
|
<tr>
|
|
<td><b><em>fv</em></b></td>
|
|
<td>The 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.</td>
|
|
</tr>
|
|
<tr>
|
|
<td><b><em>type</em></b></td>
|
|
<td>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.</td>
|
|
</tr>
|
|
</table>

<h3>Notes</h3>
|
|
<p>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>
