Calculating rental period and cost

Hi everyone.

I need to calculate the total cost given the number of (week) days the equipment was rented.
This is the info:

Start date (A2)
End date (B2)
Total days (B3) (=networkdays(A2,B2))

Rates
Daily (1-3 days) at $75
Weekly (4-5 days always equal to 5) at $375
Monthly (= 22 days) at $1,400

After some help from Google, I found the formula below works to give me the total $.
=$D$1*MOD($B$3,7)*(MOD($B$3,7) < 5)+$D$2*((MOD($B$3,7) > 4)+INT(MOD($B$3,22)/7))+$D$3*INT($B$3/22)

(the formula above has spaces between the > and <, otherwise, it won' post)
However, I still need to know the breakdown of how many months, weeks, and days B3 equals to. Anyone has any ideas how I can get this breakdown?

? Months
? Weeks
? Days
Total = B3


Thank you!

is this real calendar, days , weeks , months
you have the start and enddate
you could use
https://exceljet.net/excel-functions...tedif-function
=DATEDIF(start_date,end_date,"m")
Unit Result
"Y" Difference in complete years
"M" Difference in complete months
"D" Difference in days
"MD" Difference in days, ignoring months and years
"YM" Difference in months, ignoring days and years
"YD" Difference in days, ignoring years

IF you want the number of DAYS in B3 changed
How many days in a month ?

weeks = B3 / 5
