How to Convert a Percentage to GPA (4.0, 5.0 and 10-Point Scales)

Many students are given a percentage but asked for a GPA on applications, scholarship forms or transfer papers. There is no single official conversion that every school accepts. What you can do is use the scale your own school or country publishes, and understand how the common ones work.

Why there is no universal formula

A percentage measures how many marks you earned. A GPA is a scale built from letter grades, and each school decides which percentage range earns which letter. A 90 percent may be an A in one system, an A- in another and a first-class result in a third. Always start with the table from your institution.

A common US-style 4.0 table

Many US schools use ranges similar to these. Treat them as an example, not a rule.

• 93 to 100: A (4.0)
• 90 to 92: A- (3.7)
• 87 to 89: B+ (3.3)
• 83 to 86: B (3.0)
• 80 to 82: B- (2.7)
• 77 to 79: C+ (2.3)
• 73 to 76: C (2.0)
• 70 to 72: C- (1.7)
• 67 to 69: D+ (1.3)
• 65 to 66: D (1.0)
• Below 65: F (0.0)

So an 88 percent would be a B+, which is 3.3 on this table. A course average of 91 would be an A-, or 3.7.

The 10-point CGPA scale

Some systems, such as those used by many schools in India, report a CGPA out of 10. A widely used rule of thumb there is to multiply the CGPA by 9.5 to estimate the percentage. A CGPA of 8.0 becomes roughly 76 percent. This is only an estimate and only valid if your board or university uses that rule.

The 5.0 scale

Some universities, for example in parts of West Africa, use a 5.0 scale where a high percentage band maps directly to 5.0, the next band to 4.0, and so on down. The cut-offs differ between institutions, so read your grading handbook instead of relying on a general table.

How to convert for an application

1. Find your institution’s official grading table.
2. Match each course percentage to its grade points.
3. Multiply grade points by credits, add them up and divide by total credits. Our guide to calculating your GPA shows the steps.
4. If the form asks for a specific conversion, such as a credential evaluation, follow that service’s instructions instead of your own.

Do not round up on your own

Report the number your school’s table gives. Admissions offices usually recalculate it anyway, and an inflated figure can cause problems later.

Worked example: preparing grades for a US application

Suppose your transcript shows an overall 78% and the application asks for a GPA on a 4.0 scale.

1. Read the instructions first. Many universities and scholarship providers say “report your grades as they appear on your transcript” and convert them themselves, or ask for a credential evaluation.
2. If they ask you to convert, use the table they provide. If they give none, use your own institution’s official conversion, which may be printed on the back of the transcript.
3. Only then use a general table like the one above, and say which table you used.

On many US-style tables, 78% is a C+ (about 2.3), but on a scale where 70% and above counts as first-class, the same mark could convert much higher. That is why the source of the conversion matters more than the arithmetic.

FAQ

What is 85% in GPA?

On a typical US-style table, 85% is a B, which is 3.0 on a 4.0 scale. Some schools treat 85% as an A−, so check your school’s table.

What is 90% in GPA?

On most US-style tables, 90% is an A− (3.7) and 93% or more is an A (4.0).

Can I convert a 10-point CGPA to a 4.0 GPA?

A rough method is CGPA ÷ 10 × 4, so 8.0 becomes 3.2, but many universities and evaluators use their own tables. See CGPA to percentage (India) for more detail.

Is there a calculator for percentage to GPA?

Use the GPA Calculator to work out a GPA from course grades, and the letter grade to percentage chart to check which letter your percentage falls into.

Conversion tables vary by school and country. Your institution’s official policy always takes priority.
