WES iGPA Calculator — Convert International Grades to a US 4.0 GPA

Estimate your WES iGPA: enter each course's US-equivalent letter grade and credit hours to get the credit-weighted 4.0 GPA that US and Canadian universities read.

US-equivalent gradeCredit hours
—

Convert each of your home-country grades to its US-equivalent letter grade first, then enter the credit hours. This is a planning estimate — an official WES evaluation is a paid, course-by-course service.

Formula

iGPA = Σ(US grade point × credit hours) ÷ total credit hours · credit-weighted, so a heavy course moves the result more than a light one

Read this before you trust the number

This is an estimate, not an official evaluation. WES does not publish its exact conversion tables. Its evaluators work from institutional grade distributions, country-specific norms, accreditation and the reputation of your institution, and they convert course by course rather than applying one blanket multiplier to your CGPA.

Use this calculator to find out roughly where you stand before deciding whether an official evaluation is worth ordering, and to understand which of your courses are dragging the number down. Universities that require a WES report will need the official one.

The one rule that is certain: credit weighting

Whatever else varies, the arithmetic is a credit-weighted average. Each course's US grade point is multiplied by its credit hours, the products are summed, and the total is divided by the credit hours attempted. That has an important, predictable consequence:

CourseCreditsContribution
Advanced theory — failed50 quality points, 5 hours in the denominator
Physical education — top grade14 quality points, 1 hour in the denominator
Result6 hours4 ÷ 6 = 0.67

A single heavy failure overwhelms a fistful of easy A grades. If you still have electives to choose, the value of scoring well in your high-credit core courses is disproportionate.

Typical conversions by source system

Source systemTypical mapping
India — 10-point CGPA9.0–10.0 → 4.0 · 8.0 → 3.5 · 7.0 → 3.0 · 6.0 → 2.5 · 5.0 → 2.0
India — percentage85%+ → A (4.0) · 75–84% → B+ (3.3) · 70–74% → B (3.0) · 60–69% → C+/C · 50–59% → D+/D
UK — degree classificationFirst → A · Upper Second → B+ to A− · Lower Second → B to C+ · Third → C
China — 100-point85–100 → 4.0 · 75–84 → 3.0–3.7 · 60–74 → 2.0–2.7 · below 60 → 0.0

These mappings are widely used guidance, not WES's official tables. A 70% from one institution can convert differently from a 70% at another, because WES takes the grading context of the awarding institution into account.

What the official evaluation involves

ItemDetail
Type needed for admissionsCourse-by-Course evaluation, not Document-by-Document — only the former produces an iGPA
DocumentsSealed transcripts sent directly by your institution, plus degree certificates
CoverageAll courses, including electives, laboratories and projects
ValidityA completed evaluation remains valid for five years and can be sent to multiple institutions

Frequently Asked Questions

Is this the same as an official WES evaluation?

No. This is a planning estimate built from the published methodology and commonly used conversion guidance. WES does not disclose its exact tables, and a real evaluation converts course by course while taking your institution's grading standards into account. Order the official report for any application.

How does WES calculate an iGPA?

It converts each course individually to a US-equivalent letter grade, assigns that grade's 4.0 value, multiplies by the credit hours, sums the quality points and divides by the total credit hours attempted. The result is a credit-weighted average, not a simple mean of your grades.

What does WES do with my Indian CGPA?

WES does not divide your CGPA by a fixed number. It maps grades from your institution's scale using published guidance on the Indian 10-point system — typically 9.0–10.0 to a 4.0, 8.0 to about a 3.5 and so on — then applies the credit-weighting. The result is often higher than a naive division by 2.5.

Do heavy courses really matter that much?

Yes, and this is the single most useful thing to understand. Because the average is credit-weighted, a failed 5-credit course followed by an A in a 1-credit course yields about 0.67. Weight your effort toward your high-credit core courses.

Which evaluation type should I order?

Course-by-Course. Universities almost always require it for graduate admissions because it produces both an iGPA and US credit equivalents. Document-by-Document is cheaper but does not generate a GPA and is normally only used for employment or immigration purposes.
