About
Compares a fixed deal taken at the start of each historical window with a floating path that keeps the deal’s margin over Bank Rate locked at inception, and with staying on SVR / revert-to.
Floating rate in month t = Bank Rate(t) + (deal rate at start − Bank Rate at start). This is an outcome history, not a forecast. 2-year variable is modelled as a Bank Rate tracker (the BoE series also includes some SVR-discount deals). Payments assume capital repayment with a 25-year remaining term.
Rates are Bank of England quoted averages. Headline rates only: product fees are not in the published %, and remortgage costs are excluded.

Outcome chart
If history repeated: monthly payment paths after each past start date. Lines are medians; bands are the 25th–75th percentile.
Win-rate summary
Share of past windows where total payments on the floating path (or SVR) cost less than the fixed deal available at the start.
Distribution of saving vs fixed
One value per historical window: total fixed payments minus total floating (or SVR) payments. Positive means the floating path was cheaper.
