What is my percentage with fractional partial-credit points?

How we calculated this

This is the same points-aggregate division used everywhere on this site: earned divided by possible. Fractional points are handled with full precision, then rounded only for display. Using the example values above, 37.5 out of 50 is 75.00%.

Limitations

This site does not grade or evaluate individual answers; it only totals the partial credit you already assigned. Any dispute about how much credit a specific answer earned is between you and your instructor.

Common mistakes

A common error is rounding individual item scores before adding them, which can shift the final total by a fraction of a point compared to summing the exact values first. Add up the exact partial-credit amounts your instructor assigned per item, then let this calculator handle the division and display rounding in one step.

Frequently asked

Do I need to round my partial-credit points first?

No; enter the exact fractional value your instructor gave, and this tool preserves full precision until the final display.

How is this different from Test Percentage?

Nothing mathematically; Test Percentage is the same calculation, this version is framed specifically for fractional partial-credit totals.

What if different questions had different possible partial-credit scales?

Add each question's actual earned and possible points into the totals; the scale each question used internally does not matter once you have its final earned and possible values.

Can earned points exceed possible points?

Only with an explicit bonus; ordinarily earned points should not exceed possible points, so double-check your totals if the calculator returns a result over 100%.

My instructor deducts in half-point increments. How do I total those?

Subtract each half-point deduction from that question's possible points, then sum the resulting earned values across every question before entering the total here; entering the deduction count instead of the remaining points will give the wrong earned total.

Why does a small fraction of a point matter on a long test?

Because many small fractional deductions compound across dozens of questions the same way one large deduction would; a test with 40 items each losing a quarter point adds up to 10 full points, which is why keeping exact fractional totals (rather than rounding each item first) protects the accuracy of the final percentage.
