In developmentThis website is in development and is not yet live. The content is illustrative and is still being finalised and reviewed. It is general information only, not financial advice and not a financial promotion.
This is the comparison that is rarely put side by side: how much a £50,000 release actually grows to
when the interest rolls up and nothing is repaid. We hold the amount released constant and vary only the interest
rate, so you can see clearly how much the rate you are offered changes the long-run cost. It is an honesty ranking,
not a recommendation.
Rates are typical published ranges, not lender quotes. The rates below (6.00%, 6.90%, 7.75%)
represent a typical published lifetime mortgage range as at June 2026, not a specific lender or product. Your own
rate depends on your age, property, the amount released and the plan chosen. No voluntary repayments are assumed
and interest compounds annually. These are illustrations of compounding, not offers or forecasts.

Why the rate matters so much. On the same £50,000 release left to roll up for 20
years, the gap between the lowest and highest rate shown here is about £62,136. That difference is the
single strongest argument for shopping the rate and taking advice, rather than accepting the first plan offered.
How this is measured
Each figure is the amount released grown at the stated annual rate over the stated number of years, with interest
compounding once a year and no voluntary repayments. This mirrors how a lifetime mortgage balance accrues when
nothing is paid month to month. Only the rate is varied so the effect of pricing is isolated.
Sources to confirm: published lifetime mortgage rate ranges from provider product sheets and market rate trackers
for the rate band shown. The rates are stated as typical published ranges and are not tied to any named lender or
product. Actual costs depend on the real rate offered, any repayments made and the length of the plan. Figures
