The next time the RBA moves rates, don't look at the newspaper to see what it "means" for your family. The media loves a headline, but they aren't looking at your loan balance.
For the typical Australian family with a $694,000 mortgage and a $121,108 household income, a single 0.25% hike "leaks" $1,740 per year straight out of their budget. But that’s just the generic math. The real cost depends on your mortgage’s "Math Personality"—the specific, often hidden ways your bank calculates interest every single day.
The Source of Truth: Publicly Disclosed Logic
Most mortgage mechanics are not proprietary secrets; they are defined in publicly available documents like General Terms & Conditions. By extracting data from these 80-page PDS (Product Disclosure Statement) documents, we can identify a bank’s exact calculation constants—such as whether they use a 365 or 366-day year and precisely when interest is debited.
We aren't building a calculator that makes assumptions. We are building an Independent Shadow Ledger that uses the bank’s own "PDS-perfect" logic to ensure cent-perfect accuracy.
The Pillars of a Perfect Twin
You don’t need to link your bank account to find the truth. Because the "rules" of every major lender are already pre-loaded into entitlemate, you only need three data points to calibrate the engine to your specific loan:
- Current Loan Balance: The base for daily accrual.
- Interest Rate: The driver of the daily cost.
- Last Payment Amount: The confirmation of your repayment rhythm and the indicator of sensitivity to future rate hikes.
The "Ghost" in the Machine: Offset Auditing
While the three points above build the standard twin, the Offset Balance is the critical "4th variable" that dictates how much interest is actually charged.
A unique feature of entitlemate is its ability to "detect" a missing offset. By comparing what the bank charged vs. what the Digital Twin expected, we can reverse-calculate the weighted average balance of your offset account. This empowers you to see if your "100% offset" is actually working as promised every single day.
Independent by Design: Gatekeeper-Free Truth
We chose to build entitlemate outside of the traditional app store "walled gardens" to ensure that our logic remains independent and beyond the reach of corporate gatekeepers.
- Gatekeeper-Free: We don't wait for Apple or Google to "approve" the math. When the rules of finance change, our engine updates immediately.
- Privacy First: entitlemate is built as a direct-to-user utility. You access the truth directly through your browser, maintaining a secure relationship between you and your data. No real-world account access is requested or required.
- Truth Seeking: Our priority is validation, not engagement metrics. By bypassing the stores, we remain accountable only to the math and the families who rely on it.
