Work out tax deduction summary instantly with clear inputs, formula shown and shareable results.
Each deduction head carries its own cap, so spending beyond it buys no relief. Summarising claimed against allowed amounts shows how much of your outlay is genuinely tax-efficient and how much is simply spending.
Allowed deductions
Allowed = min(each claim, its cap); saving = allowed × marginal rate
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.
The statute fixes the maximum deduction per head. Anything beyond it reduces cash without reducing tax.
At the marginal rate, because they remove income from the top slab first.
