Maintenance calorie intake varies from person to person. It all depends on age, sex, height, weight, activity level - just like when you lose weight.
I'm maintaining my weight, I am done with losing weight. However, it will always go a little up and down, there is no way you can avoid that.
If I were you, go back to your weight loss intake, drop a kilo or two until you're happy with the weight, then add an extra hundred calories per day and see where that takes you. If you still lose weight, add another hundred. Give it a week or two before you raise your RDI per time. THis should give you an idea of how many calories you can/should consume.
Maintenance is tricky business. It's a fine balance. Just keep doing good - you'll get it.
