Reverse mortgage calculator

This guide follows the Korean HF reverse mortgage calculator for age, spouse age, home price, payment method, payment type, withdrawal limit, and guarantee fees.

Eligibility and applied values

The Korean reverse mortgage model applies to ages 55 to 90 and uses the younger spouse age when a spouse age is entered. The applied home price is capped at KRW 1.2 billion.

Housing types include general housing, senior welfare housing, and residential officetel. Welfare housing and officetel use a 0.95 factor in the Korean source, so the same price and age can produce a lower monthly payment than general housing.

Payment methods

The calculator supports lifetime, lifetime mixed, fixed-period mixed, loan repayment, and preferred payment methods. Withdrawal-limit methods reduce the remaining monthly pension because part of the guarantee is reserved for withdrawal.

Payment types include fixed, front-loaded, and gradual increase. Front-loaded types use 120, 130, 140, or 150 percent in the early period and a lower later payment; gradual increase starts lower and increases 4.5 percent every 3 years.

Fees and 2026 table

The 2026 March HF monthly table is reflected in the Korean source, including the 3.13 percent increase from the prior year. The English calculator calls the same table through calculateReverseMortgage.

The initial guarantee fee is 1.0 percent of the applied home price and the annual guarantee fee rate is 0.95 percent. Preferred payment can add up to 20 percent, but the source only applies it when the preferred product and home-price condition are satisfied.
