About LoanTrakIQ

LoanTrakIQ is a browser-based home loan calculator for modelling new loans, forecasting existing loans, and comparing loan products with realistic repayment behaviour. It is built for borrowers who want to understand how rates, fees, repayment changes, lump sums, redraws, and target payoff dates can affect the lifetime cost of a loan.

What it does now

New loan forecasts

Model a new home loan from the start date, loan amount, term, rate, repayment frequency, fees, and expected repayments. LoanTrakIQ calculates a dated amortisation schedule, payoff date, interest cost, total fees, total cost, and comparison-rate estimates from the entered cashflows.

Existing loan forecasts

Start from your current balance and remaining term to forecast where the loan is heading. You can test changed repayments, extra repayments, lump sums, redraws, future rate changes, and fee changes without needing a backend account or lender login.

Product comparison

Compare a current product against an alternative product using the same balance and remaining term. Each side can have its own rates, fees, and dated events, so the comparison reflects more than a headline interest rate.

Dated events

Add future events to model how a loan changes over time. Supported events include lump sums, redraws, repayment changes, extra repayment changes, rate changes, monthly fee changes, annual fee changes, offset deposits, offset withdrawals, and offset balance changes.

Offset account modelling

Add a starting offset balance, monthly offset contributions, monthly withdrawals, and dated offset events. Interest is calculated on the modelled interest-bearing balance, so you can estimate the effect an offset account has on interest and payoff timing.

Shareable scenarios

Copy a scenario link to reopen the same calculator mode, fields, dated events, offset assumptions, and comparison inputs later. The scenario is stored in the link itself, so it works without an account or backend storage.

Target payoff repayment

Enter a target payoff date to calculate the repayment needed to reach that date. If you also enter your planned repayment, LoanTrakIQ shows the target repayment alongside your forecast so you can see the gap.

Standard amortisation comparison

Compare your entered scenario against a standard repayment path using the same loan, rate, term, and fees. This makes extra repayments, offset assumptions, lump sums, and other changes easier to understand against a plain baseline.

Extra repayments forecast

View an automatic curve of extra repayment amounts to see how much time and interest each level could save against the standard repayment path.

CGT land cap impact

Estimate the capital gains tax exposure that can arise when a main residence is on land above the 2 hectare exemption cap. The model compares the exempt main-residence portion with the CGT-exposed excess land and estimates tax drag using your entered marginal tax rate.

Charts, schedules, and CSV export

Results include summary figures, interactive balance charts, schedule previews, and CSV downloads. The CSV schedule can be used for deeper analysis, record keeping, or conversations with a broker or adviser.

How the calculations work

Calculations run in your browser. Interest accrues daily and is charged on the selected monthly day. Repayments, fees, lump sums, redraws, and dated changes are applied on their modelled dates. Comparison rates are estimated from the modelled cashflows you enter.

Important limits

LoanTrakIQ provides general information only and is not financial advice. It is a planning model, not a lender statement. Real loan contracts may include rules, timing, fees, offsets, redraw limits, or rate mechanics that are not fully captured here.

Future features

Planned additions include a saved scenario library, printable reports, and richer side-by-side scenario comparisons.
