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

A 2% rate equals 200 basis points, 20 per mille and decimal 0.02. Adding 25 basis points to 10000 changes it by 25.

1 bp = 0.01% = 0.0001; money change = amount × chosen bp × 0.0001.

Worked example

Enter these known values and leave the other values blank.

Assumptions and limitations

  • Signed values can represent increases or decreases. The selected money portion is entered in basis points independently of the conversion fields.
  • Enter all monetary amounts in a single currency. Retained currency conversion factors are a captured static snapshot, not live exchange rates.
  • Clear a known field before solving for it. Locks retain chosen inputs; inconsistent locked values need correction. Reset restores the captured defaults.
