I did this calculation a while back. It's worth sharing:

1. So far in the US ~170,000 people have died of covid. Let's say we're only half way through and 340,000 will die this year.

2. The average age of those dying is about 80, and nearly all of them have at least one comorbidity. The life expectancy for men aged 80 years is about 7 years, and for women it's 9 years. However - using this calculator - adding in high blood pressure drops this to about 4 years. To be safe let's assume that the life expectancy of people dying of covid - had they not died of covid - would have been 5 years.

3. So the total number of days lost to covid will be 340,000 * 365 *5 = 620,500,000 days.

4. Shared between 336,000,000 people that equates to an average reduction in life expectancy of 1.8 days each.
