What percentage of your contacts would remain if you deleted everyone you haven’t spoken to in the past two years?

To answer this question, start by determining the total number of contacts in your list. Then, identify how many of those contacts you have communicated with in the last two years. Subtract the number of contacts you haven’t spoken to in two years from the total number of contacts to find those you have interacted with recently. Finally, calculate the percentage of contacts remaining by dividing the number of recent contacts by the total number of contacts, and multiply by 100 to convert it to a percentage. For example, if you have 200 total contacts and you have spoken with 80 of them in the last two years, you would be left with 80/200, equaling 40% of your contacts.
