Google Sheets – Calculate Cost Based on Time Increments

formulasgoogle sheets

I am working with a fee sheet that goes up in $ increments based on time and I would like Google Sheets to do the math to calculate the cost based on the time entered into a cell.

Example: a time value of 1 entered into a cell will always equal $800.
Every additional 15 mins adds an additional $100 to the original $800.
i.e.- 1 hour = $800, 1.25 hrs=$900, 1.5 hrs=$1000

I would like to enter the time in one cell and have the sheet calculate the cost into another cell.

Best Answer

BASE + (TIME - BASE) / 15min * EXTRA$

=800+(A4-1)/0.25*100
