Foster said by April the force expected to still have 520 fewer police officers and 500 fewer PCSOs than in 2010 and the force was facing a budget shortfall.
“The funding formula used to distribute police funding nationally also leaves the force £43m short every year,” he said.
“As a region, we continue to be short changed and ripped off, when it comes to the allocation of police resources.
“In 2026-27, the force is facing a budget shortfall of £41.1m.”
He encouraged the public to have their say while recognising households were under pressure.
“We know people are under pressure, and any decisions about funding must be taken carefully, thoughtfully and transparently.
“At the same time, we must ensure the police have the resources they need to tackle crime, protect the public and support victims.
“I would encourage residents, businesses and community groups across the West Midlands, to take part and share their views.”
The public consultation is open until 30 January.
