Wojsko komputowe is a type of military units used in Polish-Lithuanian Commonwealth in 17th century and 18th century.

Until mid-17th century Polish forces were divided into permament units (Polish wojsko kwarciane) and supplemental units (Polish wojsko komputowe, also wojsko suplementowe), which were created in the time of military needs. In 1652 this division has been annulled, and both types of forces have been merged into wojsko komputowe.

The ethymology of the name is from Latin computatio (account, calculation), and Old Polish komput - army budget which was voted for by the Commonwealth parliament, the Sejm.

Wojsko kwarciane was composed from various units, both Commonwealth-born soldiers and foreign mercenaries. The Diet voted to pay for certain amount of units (portions, Polish porcje in infantry, and horses, Polish konie for cavalry).

Personnel number (which was a kept a state secret) varies, because often the commanders (hetmans) paid for additional manpower from their own purses. During peacetime, the Commonwealth komput army numbered about 12000 for the Crown (Poland proper) and 6000 for the Grand Duchy of Lithuania. During wartime it was increased to around 24000-40000 for the Crown and 8000-22000 for Lithuania.

In addition, wojsko kwarciane was supplemented with peasant-based recruits of piechota wybraniecka and from 1653, piechota łanowa , registered Cossacks (until 1699), pospolite ruszenie, royal guard , armies of magnates and cities, wojsko ordynackie .

In 1717 the Dumb Diet (Sejm Niemy ) introduced under Russian pressure komput values of 18000 for Crown and 6200 for Lithuania. This marked the beginning of Russian control over Commonwealth armies, which would last until May Constitution of Poland.
