According to the PMBOK®, there are 2 types of cost estimates: Rough order of magnitude (ROM) with an accuracy of -25% to + 75% (other frameworks quote a range of +/-50%) and Definitive estimate with an accuracy range of -5% to +10%. Some sources also list so-called preliminary estimates and budget estimates as further gradations of estimate types.
