Sources, formulas and changelog
Our engine compounds reverse-mortgage interest semi-annually, uses each product's published rate, fees and range, estimates the maximum with an age curve we disclose, tests HELOC qualification on income, and applies each province's transfer tax when you downsize. Every rule lists its source and the date we checked it.
Figures as of November 1, 2026.Every lender term, rule and assumption our reverse-mortgage tools use, with its source and the date we checked it, the formulas behind the comparison engine, and a dated log of changes. Lender facts were last checked November 1, 2026.

How the comparison engine works
Every route delivers the same money to the household: the up-front amount (after paying off any mortgage) and the monthly amount for the years you choose. The engine then steps month by month to the age you pick and records, at each birthday, what is owed, what the home is worth and what is left.
- Reverse mortgage. Balancem+1 = balancem × (1 + i) + advance, where i = (1 + rate/2)1/6 − 1 (semi-annual compounding). No payments. What is left = home value × (1 − selling costs) − balance, never below zero (no-negative-equity terms). At 6.49% a balance doubles about every 10.9 years.
- HELOC. Limit = 65% of value (OSFI B-20). Interest of rate/12 is due every month and paid from other money; those payments are grown at the investment return and subtracted from what is left, so routes compare like for like. Qualifying payment: the amount borrowed amortized over 25 years at max(rate + 2, 5.25)%.
- Downsizing. Cash freed = sale price − selling costs − mortgage − new home price − land transfer tax (provincial schedule, and Toronto/Montréal municipal tax) − legal − moving. The rest is invested and funds the monthly amount. What is left = new home × (1 − selling costs) + investments.
- Sell and rent. Proceeds after costs are invested; rent (rising yearly) and the monthly amount come out of the investments. What is left = investments.
How we estimate the maximum by age
Canadian lenders publish a maximum (HomeEquity Bank 55%, EQ Bank (Equitable Bank) 40%, EQ Bank (Equitable Bank) 55%, EQ Bank (Equitable Bank) 59%, Home Trust Company 55%, Bloom Finance Company 55%) and say the amount depends on age, home value, location and property type. None publishes the age table, so ours is an estimate: it rises with the youngest owner's age and reaches the maximum for the oldest borrowers.
| Age | 55 | 60 | 65 | 70 | 75 | 80 | 85 | 90 |
|---|---|---|---|---|---|---|---|---|
| Share of value | 20% | 28% | 36% | 42% | 47% | 51% | 54% | 55% |

Changelog
- 2026-11-02: The comparison now prices each product as its lender does: CHIP lump sums at CHIP rates, scheduled monthly advances only on products that offer them (HomeEquity Bank Income Advantage at 7.36% variable with a $1,000 minimum; EQ Bank Flex adjustable at prime + 2.34% from $500 a month for up to 20 years; Home Trust EquityAccess+). Added Home Trust EquityAccess (four lenders, one sold through brokers) and a per-lender panel for your age, home and province.
- 2026-11-02: HELOC route: interest can now be drawn from the line itself, it is marked not possible without qualifying income, and the first-year payment shows the year's average interest rather than the first month's. Text-size control now scales the calculators too.
- 2026-11-01: Site rebuilt on the MITEY site kit. Lender terms re-read: HomeEquity Bank CHIP special rates as of October 29, 2026 (5-year 6.49%), posted rates (5-year 7.09%), fees and prepayment charges; EQ Bank Flex Lite, Flex and Flex Plus rates and ranges; Bloom rates and fees. FCAC reverse-mortgage guidance (page dated 2025-10-15).
- 2026-11-01: Bloom's website is now bloomfin.ca; the old bloomfinance.ca address belongs to an unrelated firm, so we don't link to it.
- 2026-10-29: Bank of Canada policy rate rose from 2.25% to 2.50%; HomeEquity Bank and EQ Bank now state prime at 4.70%. Our HELOC example rate follows.
