For adjustable-rate HECMs with a line of credit

HECM Line of Credit:What Happens If You Make Payments?

See how voluntary monthly payments can affect your HECM loan balance
and available line of credit over time.

On an adjustable-rate HECM, unused line-of-credit capacity grows at the current HECM rate plus the 0.50% annual FHA mortgage insurance premium. Voluntary payments can restore borrowing capacity, and that restored amount can then grow under the same formula.

Not for fixed-rate HECMs. Fixed-rate HECMs do not provide a reusable line of credit after partial repayment.

Build Your HECM Scenario

If you already have a HECM, use figures from your current servicer statement. If you’re exploring a HECM, enter estimates for the scenario you want to test.

Edit the white fields below to match the HECM you want to illustrate.
$
Use the current HECM principal balance shown on the statement, or enter the proposed starting balance for the scenario you want to explore.
$
Use the amount currently available to draw, or enter the proposed available line of credit for the scenario you want to explore.
%
Use the current rate shown on your servicer statement, or enter the estimated rate for a HECM scenario you are considering. Your adjustable HECM rate is the index plus the loan’s margin. Do not add the 0.50% FHA MIP. The calculator adds it automatically.
current or estimated interest rate + 0.50% annual FHA MIP. Used for projected loan-balance and line-of-credit growth.

Test a Voluntary Payment

Monthly principal and interest payments are not required on a HECM. Enter any voluntary monthly amount you would like to test.

$
For this estimate, the calculator first adds the month’s interest and FHA MIP, then applies the voluntary payment. Actual results may vary based on payment timing and servicer practices.
A large voluntary payment may also create a tax benefit. Some accrued HECM interest may become deductible when it is actually paid, depending on how the loan proceeds were used and your individual tax situation. Check with your CPA or tax adviser before making a large payment.
Numbers Based on a 1-Year Projection
These numbers are estimates only, not exact future amounts. Your actual HECM balance and available line of credit will differ from the projections shown here. Your servicer is the best source for current loan information, and your loan officer can help you evaluate a specific scenario. This calculator is designed primarily to help you understand how voluntary payments can affect a HECM and to give you a reasonable ballpark estimate.

Payments restore borrowing capacity when made. That restored capacity can then participate in later line-of-credit growth.
IMPORTANT: KEEP THE HECM OPEN
Do not pay the loan balance to zero if you intend to keep the line of credit available. A full payoff ends the HECM and the line of credit. If you are making a large voluntary payment, confirm with your servicer how much balance should remain.
See How the Line of Credit Can Grow Over Time Try 15 years and see what the available line of credit could look like. Think about future borrowing capacity for a medical emergency, care needs for a spouse, a major home repair, or an unexpected car expense. This is the big deal. An unused adjustable-rate HECM line of credit can grow over time, potentially creating substantially more borrowing capacity later in retirement. That can mean a financial liferaft in an emergency and more freedom to use home equity when it matters most.

Important Assumptions

Monthly principal and interest payments are not required on a HECM. Borrowers must continue to meet the loan obligations, including living in the home as their principal residence, keeping property taxes and homeowners insurance current, paying applicable HOA dues, and maintaining the property.

Actual HECM balances, interest rates, FHA mortgage insurance charges, available proceeds, payment application, line-of-credit availability, and future results can differ from the estimates shown here. Actual loan information and available proceeds are determined by the loan documents and servicer.

HECM borrowers remain responsible for meeting the requirements of the loan, including occupying the home as their principal residence, keeping property taxes and homeowners insurance current, paying applicable HOA dues, and maintaining the property.
