If the situation is taking place now, at the moment of speaking, you could say:
'It should be 100,000$'
'It was supposed to be 100.000$'
'It was meant to be 100,000$'
Otherwise you should say:
'It should have been 100,000$'
'It was supposed to have been 100,000$'
'It was meant to have been 100,000$'
Don't forget to use commas instead of full stops concerning 'thousands', and use full stops in place of commas concerning 'decimals'.
