Work out gst inclusive price instantly with clear inputs, formula shown and shareable results.
Adding tax to a base price gives the invoice value, and for intra-state supply the tax splits equally into central and state components. Note the tax is 18% of the base but only about 15.3% of the final price.
Tax-inclusive price
Inclusive = base × (1 + rate); each component = tax / 2 for intra-state supply
Tax figures are estimates based on the rates, caps and thresholds you enter. Real rules differ by jurisdiction and change every year, and personal circumstances alter the outcome. This is not tax or financial advice — confirm with a qualified adviser.
Because the rate applies to the base, while the share is measured against the larger inclusive total.
For inter-state supply a single integrated tax applies instead of two components.
