Question about the calories calculated by MFP

Hi, I'm a new user of Myfitnesspal and I've been set to eat 2400 calories per day to lose 0.5 kg per week to my goal weight which is 15 kilograms lesser than I am now.

My question is, are the 2400 calories calculated the baseline for maintaining weight by which I need to consume less than this to lose weight? Or can I still eat 2400 calories and still lose 0.5kg per week?

I'm a bit confused because I feel like 2400 is very high for me. But I've googled around and a lot of people said that MFP has quite accurate calories calculation.

For context, I set that I'm only lightly active.
