Starting Line Ratio Calculator

The Starting Line Ratio calculator will evaluate and display the Starting-Line Ratio. Enter the rear-end ratio and the transmission first gear ratio into the Starting-Line Ratio Calculator. Like Starting Line Ratio calculator, you may also use Holding Period Return Calculator.

Online Starting-Line Ratio Formula

The following formula is used to calculate the Starting-Line Ratio. 

  • Where STLR is the Starting-Line Ratio
  • RER is the rear-end ratio 
  • TFG is the transmission first gear ratio 

To calculate a starting-line ratio, multiply the rear-end ratio by the transmission first gear ratio.

How to Calculate Starting-Line Ratio?

The following example problems outline how to calculate Starting-Line Ratio.

Example Problem:

  1. First, determine the rear-end ratio.
    • The rear-end ratio is given as: 6.5.
  2. Next, determine the transmission first gear ratio.
    • The transmission first gear ratio is provided as: 7.3.
  3. Finally, calculate the Starting-Line Ratio using the equation above: 

STLR = RER *TFG

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

STLR = 6.5 *7.3 = 47.449999999999996
