Adequate salary expectations for move from Germany to Singapore?

I am working as a Senior Data Scientist for an IT implementation firm in Germany and I have the opportunity to move to our Singapore office. That would also mean a change of contract. I suppose there is some room for negotiation, so I want to come up with an informed number myself before figuring out the details with my managers.

Currently, I am earning 95k€ p.a., living in Munich and I can comfortably set aside about 1.5k€ per month. If I moved to SGP, that would be for >6 months, so I would pay Singaporean taxes (a lot less than my German average 40%), but also cost of living would be much higher. As to how high, I am not sure.

Basically, I am thankful for any inputs, be it your own experience from similar moves or any important factors to consider about Singapore!
