About Stamp Paper Value Calculator

Stamp duty on an instrument is an ad valorem charge on the consideration or value, subject to a statutory cap for some instruments. Additional executed counterparts attract only a nominal duty each, and because stamp paper and e-stamp certificates are issued in fixed denominations the total is rounded up.

Formulas

Duty on the principal instrument

Duty = Instrument value x Rate %, capped where a statutory maximum applies

Total stamp value

Total = Principal duty + Counterparts x nominal duty, rounded up to the nearest issuing denomination

Worked example

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
Indicative estimate only. Fees, entitlements, limits and formulas vary by jurisdiction, statute, policy wording and the facts of the case. This is not legal, tax, insurance or financial advice — confirm with a qualified professional or the relevant authority.

Frequently Asked Questions

What if an instrument is under-stamped?

It is generally inadmissible in evidence until the deficit and a penalty are paid, which can be a multiple of the shortfall.

Do duplicate copies need full duty?

Usually not. Counterparts and duplicates attract a small nominal duty provided the principal instrument is fully stamped.
