Reliable calorie calculator?

[pimpinpurplepon]

I've been searching the internet for a calculator that tells how many calories you need. One told me 1600, another told me 1300, and one 800! If anyone knows of a good website a link would be greatly appreciated!
Also, not sure if this is the place to post, but would anyone here know about how many calories you need to cut off your suggested intake to begin losing weight?
