The divisional charts — subdividing the sign to see what the sign conceals
A varga takes each 30° rāśi, cuts it into equal parts, and maps every part onto a sign of the zodiac by a fixed rule. The result is a second chart, read for one department of life. The sixteen nest rather than merely accumulate: the ṣaḍvarga of six sits inside the saptavarga of seven, inside the daśavarga of ten, inside the ṣoḍaśavarga of sixteen — and each grouping carries its own Viṃśopaka weighting out of twenty, so the same varga counts differently depending on which set you are working in.

Viṃśopaka weights
Each column totals twenty. A varga's importance is not fixed — the navāṃśa is worth 5 of 20 in the ṣaḍvarga scheme and only 3 in the ṣoḍaśavarga, where the ṣaṣṭyāṃśa takes the largest share after the rāśi chart itself.

Varga dignity names
When a graha falls in a favourable sign across several vargas at once, the classics give the resulting condition a name. The count runs from two upward, and the naming set differs by which grouping you are using.
