This tool calculates linear interpolation from Start value, End value, Progress (%). Enter each quantity in its labelled field, then use the formula below to check the calculation.

Formula

start + (end − start) × progress ÷ 100

Worked example

Start value

10

End value

50

Progress (%)

25

Applying the formula to these values gives 20 .
