How Do Interest Rates Work?

On a reverse mortgage, interest usually accrues instead of being paid monthly. Rate type shapes both how much you can borrow up front and how fast the balance grows — fixed lump-sum products versus adjustable lines of credit.

Accrual, Not a Monthly Bill

Unlike a traditional mortgage where you pay principal and interest each month, a HECM typically lets interest and MIP add to the loan balance while you live in the home as your primary residence. You still pay property charges — taxes, insurance, maintenance — but required monthly P&I is usually not part of the structure.

Two rate concepts matter. The note rate (fixed or adjustable) governs interest on your outstanding balance. Separately, an expected rate feeds the principal limit calculation that decides initial borrowing power. When expected rates rise, principal limits often fall — even before you close.

Ryan and Steve compare fixed lump-sum and adjustable credit-line structures with current assumptions so you see both proceeds and long-term balance growth. Figures are illustrative and subject to credit and property approval.

Rate Choices That Change the Product

Pick the structure that matches how you want to use equity.

Fixed-rate HECMs

Often pair with taking available proceeds at closing as a lump sum. Predictable note rate; less flexibility for unused credit lines that grow. Fit borrowers who need funds immediately and accept drawing most capacity up front.

Adjustable-rate HECMs

Usually support lines of credit, tenure/term monthly payments, or combinations. Rate can move with the index plus margin within caps. Unused credit-line growth is a hallmark of many adjustable HECMs.

Expected rate vs. note rate

Expected rate helps set the principal limit tables. Note rate drives ongoing accrual. Both matter — one for how much you start with, one for how the balance behaves later.

MIP and total cost

Annual mortgage insurance premium also adds to the balance. Looking only at the interest rate understates total cost of funds over a long occupancy.

Frequently Asked Questions

How do interest rates work on a reverse mortgage?

Interest accrues on the outstanding loan balance — amounts you have drawn plus certain fees and MIP. You typically do not make required monthly P&I payments while you live in the home, so the balance grows over time. Rate type (fixed vs. adjustable) depends on the HECM product you choose.

Are reverse mortgage rates fixed or adjustable?

Both exist. Fixed-rate HECMs often require taking most available proceeds as a lump sum at closing. Adjustable-rate HECMs usually allow lines of credit, monthly advances, or combinations, with rates that can change within product caps.

Do higher rates mean I get less money?

Generally yes. The HECM principal limit uses an expected interest rate assumption — higher expected rates typically reduce initial borrowing power. Current note rates also affect how fast the balance grows after closing.
