03 · Decomposition · Figure A

Where your gap
comes from.

The 140 bps gap between your rate and the cheapest matched product breaks into four drivers. Each is capped at how much of your gap it can explain — never the population spread.

Total gap
140 bps
Loyalty 70
Tier 38
LVR 18
Product 14
Loyalty · 70 bps

You've been on the same rate 4 years.

CBA's front-book rate today is 5.79%. The bank quietly stopped passing rate cuts to existing customers — that's where most of your gap lives.

Tier · 38 bps

Big-4 carry a structural premium.

CBA's median sits 38 bps above non-major lender medians for an equivalent loan. You're paying for the brand, not for the rate.

LVR · 18 bps

71.9% LVR is the cliff above the 70% band.

Drop below 70% LVR — through valuation, paydown, or both — and you'd unlock the cheaper LVR band most matched products price into.

Product · 14 bps

Standard Variable carries package fees.

Switching to a no-frills variable inside CBA (or to a basic variable elsewhere) drops the product premium without changing your serviceability.

04 · Benchmark

How you stack
against the market.

Even the priciest big-4 median is 50 bps cheaper than what you're paying. The long-tail best is a full 1.4% below.

Even matched against the most expensive sub-cohort (big-4 median), there's still 50 bps of headroom you could capture with a single retention call.

05 · Loyalty tax

CBA charges
new customers less.

You're at 6.89%. CBA's front-book offer for the same product, same LVR, today is 5.79% — a 110 bps loyalty tax on you specifically.

Negotiation script
Rank 2

Refinance to a long-tail lender at 5.49%.

Macquarie or Athena take you about 6 weeks. Closes the full gap if retention won't budge.

Rank 3

Drop below 70% LVR through revaluation.

A free CBA revaluation may bring you under the 70% band, unlocking the cheaper LVR tier on the same product.
