To get a percentage, you must have a formula to calculate it. Definition of percentage:-
a proportion in relation to a whole (which is usually the amount per hundred)
So, the percentage of you average amount could be something like this:-
avg(DateOfMaturity) / <Total Days>
Of course the other way is to set the Min/Max value if you don't have any method of calculating the percentage. In your case, you can set the min value as 0 while max could be 1000. So, the needle of the speedometer will be around 35.6%.
