MortgageMateAU: The Australian-Built App That Helps You Take Control of Your Mortgage

June 2025
Product Guide

For most Australians, the home loan is the biggest financial commitment they’ll ever make. Yet after settlement, it’s surprisingly hard to see the big picture—what you’re really paying in interest, how rate changes affect you, whether extra repayments make a dent, and how fast you’re actually moving toward freedom. That’s exactly why MortgageMateAU exists.

The Story Behind MortgageMateAU

In January 2025, I went looking for a practical way to track my own mortgage. I expected to find a solid Australian app. Instead, all I could find were limited spreadsheets. They were clunky, time-consuming, and didn’t give the clarity I needed.

With a background in computer programming (from the computer strand of Electrical Engineering) and 15 years running my own IT business, I decided to build a web application that made sense for everyday Australians. What began as a personal project quickly turned into something more—feature by feature, it became a complete mortgage tracking platform. It worked so well that it felt wrong to keep it to myself, so I made it available to everyone as MortgageMateAU.

What MortgageMateAU Does (in Plain English)

MortgageMateAU helps you track the mortgage you already have—no sales pitches, no loan hunting. Just clear tools that show what’s happening, why it’s happening, and what you can change to save time and money.

Core Tracking

  • Repayment tracking: Mark payments as “paid,” log extra repayments and lump sums, and keep your schedule accurate over time.
  • Balance adjustments & redraws: Record redraws and corrections so your loan balance and payoff timeline stay true to life.
  • Offset impact: Model how an offset balance affects interest and your payoff date.
  • Multiple loans & properties (plan-dependent): Track several mortgages and properties from one account.
  • Portfolio insights: View portfolio summaries and high-level metrics that make sense at a glance.

Strategy & Analysis Tools

  • Extra repayment scenarios: See how adding extra (or bi-weekly/fortnightly style structures) can shorten your term and reduce total interest.
  • Interest Rate Sensitivity: Test future rate changes and understand the effect on repayments and total cost.
  • Refinance Analysis: Compare your current loan against a prospective alternative to see potential savings and costs before you act.
  • LMI Calculator: Estimate Lenders Mortgage Insurance when purchasing or considering changes that may trigger LMI.
  • Amortisation & payoff timelines: View your repayment schedule and projected payoff based on your inputs.

Who It’s For

  • Homeowners who want to pay off their mortgage faster with clear, testable strategies.
  • First-home buyers seeking clarity and confidence from day one.
  • Property investors managing multiple loans and needing portfolio-level visibility.
  • Anyone with an Australian mortgage who wants control, insight, and less stress.

How MortgageMateAU Helps You Save

  • Save money: Discover how extra repayments, offsets, and smarter strategies reduce total interest paid.
  • Save time: Replace messy spreadsheets with one place to track repayments, balances, redraws, and scenarios.
  • Make better decisions: Use real numbers from your loan to test “what-ifs” before you commit to a change.
  • Stay organised: Keep an accurate schedule, annotate changes (rate updates, redraws, balance adjustments), and see your progress clearly.

Plans & Pricing

Choose a plan that matches how you manage your mortgage:

  • Basic – $4.95/month: Essential mortgage tracking.
  • Pro – $9.95/month: Unlocks advanced tools and strategy analysis.
  • Multi-Property – $29.95/month: Track up to 10 properties with portfolio-level insights.

What MortgageMateAU Isn’t

MortgageMateAU isn’t a loan comparison site or a lender. It doesn’t push products. It focuses on your existing mortgage and gives you the clarity to manage it better. It’s educational and informational—not financial advice.

The Road Ahead

MortgageMateAU is built for Australians first. Over time, the goal is to adapt the platform for other markets while keeping the same promise: practical tools that help people understand and manage their mortgages with confidence.
