A reverse mortgage principal limit factor, or PL factor, helps determine the proceeds available from a HECM reverse mortgage. PL factors are used to calculate the principal limit, which is the gross pool of cash available before mandatory obligations are paid.

### How PL factors are used

Principal limit factors are percentage values published in tables by the Federal Housing Administration (FHA) for purposes of calculating HECM proceeds.

The appropriate principal limit factor is selected by the lender based on the age of the youngest borrower (or non-borrowing spouse) and the expected interest rate (EIR). The appropriate PL factor is then multiplied by the maximum claim amount (usually equal to the value of the home) to determine the principal limit.

As an example, let’s assume the maximum claim amount is $300,000 and the appropriate PL factor 0.50. To calculate the principal limit, we simply multiply the PL factor by the maximum claim amount:

$300,000 (maximum claim amount) * 0.50 (PL factor) = $150,000 (principal limit)

As you can see, the principal limit in this example works out to be $150,000. This is the total pool of cash available to pay mandatory obligations such as existing mortgage balances, closing costs, property charges due at closing, set-asides, etc. The remaining portion of the principal limit is available for allocation to lump sum, line of credit, term income/tenure income, or some combination of these options.

Principal limit factors tend to increase with age. This means that older borrowers tend to qualify for more money than younger borrowers.

PL factors also tend to increase as the expected interest rate *decreases. *This means that the HECM tends to offer more money when interest rates are relatively low.
