I don't use a nutritional calculator so much anymore as I have all of my regular meals and I know roughly how they affect my body...
Vision have their own calculator but I find it more brand-related and I don't eat so much processed food...
So I found this one called 'Aminoz' and I think it works very well! It even has rough numbers for take away food like thai dishes which I find very helpful.

I will also say it's worthwhile to buy a little scale to weigh your food on from time to time and these are found very cheaply on ebay (accuracy of these cheap scales questionable at times!)
