What it means
A fixed rate stays the same for a set period. A tracker moves with a base rate. This sketches both paths with your own later-rate guesses.
Comparing
Fixed vs tracker calculator
What a fixed rate versus a tracker could cost if rates move.
Why it matters
Fixed gives certainty. Tracker can cost less if rates fall, or more if they rise. The trade-off is comfort versus flexibility.
When to use it
Use it when choosing between a fixed deal and a tracker, or when you want to stress-test what happens if rates move.
How to read the result
Treat it as a what-if sketch. Fees, exit charges and rate caps are not fully modelled. Decide on certainty as well as cost.
Your figures
Used after the fixed period and after the tracker step.
Methodology
Rules checked against published sources as of 2025-04-01.
- Fixed and tracker paths use stage rates for the years you set, then a later rate assumption.
- Payments use a full-term repayment formula at each stage rate. Mid-term rebalancing is simplified.
