GST: Add Tax vs GST-Inclusive Price

Understand the difference between adding GST to a base price and extracting GST from an inclusive price.

WHY IT MATTERS

Compare the decision, not just the headline number

A common invoicing mistake is treating a GST-inclusive price as though it were the taxable base. The GST calculator supports both directions so you can check the tax component clearly.

Scenario workflow
  1. Start with the same amount or goal for both scenarios.
  2. Use realistic rate, return and time assumptions.
  3. Compare the monthly cash flow and the total result.
  4. Consider liquidity, taxes, fees and risk before deciding.

FAQ

Scenario questions

Is this a product recommendation?

No. This page is a planning framework. Rates, returns, taxes, fees and product rules should be checked from current official sources.

Why compare more than one number?

A monthly payment or projected maturity value alone can hide total interest, liquidity, risk or time-horizon differences.

Can I change the assumptions?

Yes. Open the linked SolveKit tool and test your own amount, rate and period assumptions.
