How much will one zero cost you?
A missing assignment costs you twice: you lose the points and the total you are divided by grows anyway. That is why one zero early in a term hurts far more than the same zero late in one. Enter your points earned, points possible, and the size of the assignment.
A missing assignment does not just fail to add points, it grows the total you are measured against. That is why one zero early in a term can hurt more than three late in one, and why the honest answer is a number rather than a feeling.

Work out the cost
Both totals are on your gradebook. The third box is what the assignment you missed was out of.
Points earned and points possible are both on your gradebook. If the class uses weighted categories, run this inside the category the assignment belongs to, because a zero in a category worth 40% of the course hurts differently than one worth 10%.
Why a zero hurts twice
Missing work costs you the points you did not earn and adds those points to the denominator anyway. Your score stays where it was while the total you are divided by gets larger, so the percentage falls even though you did nothing wrong on anything else.
Early zeros hurt more than late ones
The size of the drop depends on how many points are already recorded. A 50-point zero against 100 points of graded work is enormous; the same zero against 1000 points is a rounding error. This is why the first weeks of a term are worth more attention than they get.
Check the category, not just the course
If your class weights categories, run this inside the category the assignment belongs to. A zero in a category worth 40 percent of the course does roughly four times the damage of the same zero in a category worth 10 percent, and the course-level number hides that.
Deciding what to do first
Once you know what each missing item costs, the order is obvious: largest recoverable loss first, not oldest first. Doing that by hand across four platforms is the part most people never finish, which is what SchoolOps automates. It collects every missing assignment and ranks them by exactly this calculation, free with an account.
Questions
How much does one missing assignment lower my grade?
It depends on the size of the assignment relative to the points already graded. Enter your points earned, points possible, and what the missing one was out of, and the calculator shows your grade before and after and the difference between them.
Is it worth doing an assignment that is already late?
Usually yes, and this shows by how much. Many teachers accept late work for partial credit, and even half marks on a large assignment moves the number more than finishing something small and current.
Why did my grade drop more than the assignment was worth?
Because a percentage is a ratio. The missed points count against you and enlarge the total you are measured against at the same time, so the fall is larger than the raw points suggest.
Does a zero always count?
That depends on the course. Some apply a zero automatically after the due date, others leave the assignment ungraded until the teacher acts, which makes your displayed grade look better than the real one. Either way the work is still outstanding.
