How this calculator works
The GMAT Focus Edition reports three section scores between 60 and 90 for Quantitative Reasoning, Verbal Reasoning and Data Insights, and one total between 205 and 805. GMAC says the sections carry equal weight, which makes the total a monotone function of the sum of the three section scores: a sum of 180 gives 205, a sum of 270 gives 805, and the scale between them is close to linear and reported in steps of 5. GMAC does not publish the exact conversion, so this page interpolates linearly between those endpoints. Treat the result as a good estimate, not as the score your official report will show.
Formula
estimated total = 205 + (quant + verbal + data insights - 180) x (600 / 90), rounded to the nearest 5 and kept within 205 and 805. Because the sections weigh the same, the reverse direction is missing section = section sum - the other two sections.
Worked example
A candidate with 82 quantitative, 80 verbal and 84 data insights has a section sum of 246. The estimate is 205 + 66 x 6.667 = 645, which matches the published anchor where three scores of 82 give 645.

Frequently asked questions
Is this the score GMAC will report?
No. The section scores are accurate, but the total is an estimate. GMAC states that each section weighs one third and gives the score ranges, yet keeps the exact mapping from sections to total private, and its own guidance is to compare percentiles rather than convert scores.
Can I compare this with an old GMAT score out of 800?
Not directly. GMAC says the Focus Edition total is not comparable to the classic 200 to 800 scale and has published percentile tables for the new scale instead. Use percentiles for any comparison.
Why do totals end in 5?
The total is reported in 10 point bands from 205 upward, so every valid total ends in 5. The estimate is rounded to the same grid.
How large is the uncertainty?
GMAC reports a standard error of measurement of roughly 30 to 40 points on the total, which is far larger than the rounding here. Differences of a few tens of points are inside the noise.
