FIRE Guides

Understand the model before you trust the numbers.

Each guide explains a specific part of the FIRE calculator — the assumptions it makes, how comparison works, and how to stress-test your plan.

Foundations

Calculator Assumptions

Core ETF, property, tax, and spending assumptions inside the calculator. Start here to understand what the model does and doesn't cover.

Assumptions

Set realistic ETF return, dividend, franking, property yield, vacancy, and expense assumptions when comparing investment paths.

Analysis

Use alternate scenarios and sensitivity analysis to test whether your plan still works when returns drop or costs rise.

Strategy

Model changing savings capacity over time — salary increases, family costs, debt payoff — instead of one flat number.
