How to use this calculator

  1. Enter the known values in the units shown. Results update as you type.
  2. Where results are editable, change one to solve backwards. Lock a value to hold it fixed.
  3. Use the worked example to check the method. Reset restores the starting fields.

Use the result with context

Results are estimates for planning and education. Confirm rates, taxes, fees, and legal requirements with the relevant institution or a qualified professional before making a financial decision.

Formula and method

Nominal transactions of 2,000 and money stock of 500 imply velocity of 4 over the chosen period.

Nominal transactions = price index Ă— real transaction volume; velocity = nominal transactions / money stock.

Worked example

Enter these known values and leave the other values blank.

Price index (P)
2 USD
Volume of transactions (N)
1000
Amount of money in circulation (M)
500 USD / yrs
Sum of all transactions (T)
2000 USD
Velocity of money (Vt)
4 / yrs

Assumptions and limitations

  • The price index is a multiplicative factor and the transaction volume must use its matching real-value base. Use the same monetary unit and period.
  • This is the transactions identity, not necessarily GDP velocity. All source-model quantities are strictly positive.
  • Enter all money amounts in one currency. The retained currency conversion menu uses captured historical conversion factors, not current exchange quotes.
  • Clear an unknown editable field before solving an inverse; fixed selections and output-only fields cannot be inferred.

Common questions

What does this calculation assume?

The price index is a multiplicative factor and the transaction volume must use its matching real-value base. Use the same monetary unit and period.

Are these current exchange rates?

No. Use one currency consistently; currency menu factors are a historical snapshot.
