Rough Order of estimate: -50% to +50 %

Budget estimate: -15% to +25 %

Definitive Estimate: -5% to +10%

Generally these are the etsimate terms used from PMP perspective.

 some of the mock test will give u different answer. I encountered this before and the answer given was -50 to +100 for ROM. But i suggest to follow the figure mentioned by cnppmp above.

I have provided the ranges as per the PMBOK, so you need to follow PMBOK, else you would answer wrongly...My advise for such things you need to follow the PMBOK blindly.

based on various situations range of estimates can be used as below:

Rough Order of Estimate: + -50% OR -25 to 75%

Conceptual:-30 to 50%

Preliminary:-15 to 50%

Budgetary: -  -10 to 25%

Definitive:+ -5% OR -5 to 10%

Final Estimate = 0
