formula for extremely large data divided in two sheets

I have data of around 2 million records (rows) divided in two sheets (tabs).A sample file attached. How can I apply formula on third sheet that will treat both sheet as continuous sheet.
in the third sheet I want to calculate following things
a)sum of all matirutiy value (value in column "G") for value in column "F" is in >=7<=14(i.e value in g will get added if value in column f is 7 or 8 or 9....14)
b)sum of all matirutiy value (value in column "G") for value in column "F" is in >=15<=30
c)sum of all matirutiy value (value in column "G") for value in column "F" is in >=31<=45
d)sum of all matirutiy value (value in column "G") for value in column "F" is in >=46<=90
d)sum of all matirutiy value (value in column "G") for value in column "F" is in >=91<=120
e)sum of all matirutiy value (value in column "G") for value in column "F" is in >=121<=150
f)sum of all matirutiy value (value in column "G") for value in column "F" is in >=151<=179
g)sum of all matirutiy value (value in column "G") for value in column "F" is in >=180<=269
h)sum of all matirutiy value (value in column "G") for value in column "F" is in >=270<=364
i)sum of all matirutiy value (value in column "G") for value in column "F" is in >=365<=730
j)sum of all matirutiy value (value in column "G") for value in column "F" is in >=731<=1094
k)sum of all matirutiy value (value in column "G") if value in column "F" is in >=1095<=1825
l)sum of all matirutiy value (value in column "G") if value in column "F" is in >=1826<=3650

further i need to make a table
i) sum of all value in column "G" when value in f is >=365<=730 and value in column "E" <=31-12-2019
ii)sum of all value in column "G" when value in f is >=365<=730 and value in column "E" <=31-03-2019
ans so on

in another sheet I want to extract details of those contracts where maturity value is <=10000000.The format will remain same but it will only contain details of records where value in column "G" is <=10000000.

Then in another sheet i have to calculate a) ,b), c)...... and i) ,ii) for data in sheet where value of g is <=10000000.

the formula needs to support dynamic range
Every time the number of records will increase or decrease so when i will paste the data into both sheets the range in formula should adjust them self.
customization should be easy.

Your help will be appreciated.
