GPA on the Saudi 5.0 scale (and converting to 4.0)

How the Saudi 5.0 and 4.0 scales differ from each other and from the US 4.0 scale, how to work out a GPA by credit hours, and how to plan a target without fooling yourself.

Why you’d do this

Saudi universities report GPA on either a 5.0 or a 4.0 scale, and which one applies depends on the institution. An application abroad, a scholarship form or an employer may ask for the other one, or for a US-style 4.0. The tempting shortcut is to multiply a 5.0 GPA by 0.8 and call it a 4.0. It does not work, because the scales are not proportional. The better approach is to recompute the GPA from your individual grades on the scale you need.

The same tool also answers the question students ask before every term: what GPA do I need this semester to reach a target cumulative figure, and is that even possible?

How, with the named tool

GPA Calculator runs on your device.

Choose scale and method. Under Grade scale, pick Saudi 5.0, Saudi 4.0, US 4.0 (with +/−), US 4.0 (letters only), Percentage (0–100), Enter grade points directly or Custom scale. Then under Method pick Weighted by credit hours (the usual one) or Simple average.
Enter your courses. For each row type the Course name, its Credits and its Grade. Add course adds a row, and Add semester starts another term block.
Add your previous record if you have one. Under Previous record, enter Previous GPA and Credits earned, so the cumulative figure includes work already completed.
Read the results. Each block shows Semester GPA. Below them are Cumulative GPA and Total credits. Copy summary puts it all on the clipboard.

To convert between scales, run the same courses twice: once on the scale you were graded on, and once on the target scale, switching Grade scale and re-selecting each grade. The tool does not have a “convert my GPA” button, and the reason is below.

Here is the difference in practice. Take three courses: A for 4 credits, B+ for 3 credits and C for 3 credits, weighted by credit hours.

On Saudi 5.0, A is 4.75, B+ is 4.5 and C is 3.0. The result is (4.75×4 + 4.5×3 + 3.0×3) ÷ 10 = 4.15.
On Saudi 4.0, A is 3.75, B+ is 3.5 and C is 2.0, which gives 3.15.
On US 4.0 (with +/−), A is 4.0, B+ is 3.3 and C is 2.0, which gives 3.19.

Multiplying the 5.0 result by 0.8 would have said 3.32. None of the three real answers matches it.

What to watch for

The floors differ. On the Saudi 5.0 scale, F is worth 1.0, not 0. On the Saudi 4.0 scale, F is worth 0.0. A failed course therefore pulls the two scales down by different amounts. The 5.0 grades in the tool are A+ 5.0, A 4.75, B+ 4.5, B 4.0, C+ 3.5, C 3.0, D+ 2.5, D 2.0 and F 1.0.

Saudi 4.0 is not US 4.0. In the tool’s Saudi 4.0 table, A+ is 4.0, A is 3.75 and B+ is 3.5. In the US scale with plus and minus, A is 4.0, A− is 3.7 and B+ is 3.3. The letters look alike and the points are not. Pick the scale the receiving institution asked for, not the one that looks closest.

Institutions differ, and the banner stays. The tool carries a permanent note: institutions differ in both letter cut-offs and point values, this is an estimate, and you should check your registrar’s official scale. Treat it as a planning aid and use your university’s transcript figure for anything official. UK, Indian, German and other national scales are not built in. Use Custom scale or Enter grade points directly for those.

Percentages need a companion scale. With Percentage (0–100), the tool maps each mark to a letter, then to points on the scale chosen under Map percentages using. A mark of 87 becomes B+ on the tool’s percentage bands, so it is only as accurate as that mapping matches your university’s.

Target planning reports the impossible, it does not hide it. In Target planner, enter Target cumulative GPA and Credits this term. The tool starts from your cumulative GPA and credits so far (previous record plus any courses entered) and reports what the coming term must average. For example, with a previous GPA of 3.80 over 60 credits on Saudi 5.0, a target of 4.00 and 15 credits this term, the answer is 4.80: (4.00 × 75 − 3.80 × 60) ÷ 15. That is reachable on a 5.0 scale. Now take a previous GPA of 4.00 over 90 credits, a target of 4.50 and 15 credits: the arithmetic asks for 7.50, which is above the scale’s maximum. The tool does not cap it at 5.0 and pretend the target is achievable. It tells you the target is out of reach this term and shows the highest possible figure for the scale, 5.00.

FAQ

Can I convert my 5.0 GPA to 4.0 by dividing or multiplying?

No. The Saudi 5.0 and 4.0 tables have different letter values and different floors for F, so the converted number depends on your individual grades, not only your final GPA. Recompute from your courses on the scale you need.

Why does my 4.0 result differ between Saudi 4.0 and US 4.0?

Because the point values differ. The tool’s Saudi 4.0 table gives A 3.75 and B+ 3.5. The US table with plus and minus gives A 4.0 and B+ 3.3. The same transcript can produce different results on each.

What does it mean if the target planner says my target is out of reach?

Even a perfect run of top grades this term, at the scale’s maximum, would not bring your cumulative GPA up to the target. Either the target needs more terms, or the credit count this term is too small to move the average that far.
