Help with calculation of customer retention rate in Excel file (Cohort analysis)

[tuanvu]

Hi all,

Please help me to calculate the retentaion rate of customer over months

For example,
- In January I have 4 new customer.
- In February, 3 out of 4 continue to purchase my product > retention rate is 3/4 = 75%.
- In July, 1 out of 4 purchase my product > retention rate is 1/4 = 25%

I did a example below. Please help me with the rest of the table

Thank you so much
