Enter the current value of T-bill ($) and the purchase price of T-bill ($) into the Return on T-Bill Calculator. The calculator will evaluate and display the Return on T-Bill. 

Return on T-Bill Formula

The following formula is used to calculate the Return on T-Bill. 

ROTB = (CVTB - PPTB) / PPTB *100
  • Where ROTB is the Return on T-Bill (%)
  • CVTB is the current value of T-bill ($) 
  • PPTB is the purchase price of T-bill ($) 

How to Calculate Return on T-Bill?

The following example problems outline how to calculate Return on T-Bill.

Example Problem #1:

  1. First, determine the current value of T-bill ($).
    • The current value of T-bill ($) is given as: 150.
  2. Next, determine the purchase price of T-bill ($).
    • The purchase price of T-bill ($) is provided as: 100.
  3. Finally, calculate the Return on T-Bill using the equation above: 

ROTB = (CVTB – PPTB) / PPTB *100

The values given above are inserted into the equation below and the solution is calculated:

ROTB = (150 – 100) / 100 *100 = 50.00 (%)

Example Problem #2: 

For this problem, the variables needed are provided below:

current value of T-bill ($) = 1285
