I am glad you asked this question as the over consumption of 30 grams of carbs can lead to fat gain while bulking. If you even eat one carb too many during a bulk it will go straight to your hips/butt/gut.
If you want a serious and simple answer do what Facko recommended and don't count any incidentals including but not limited to; sauces, vegetables, fiber supplements, etc. Just count the cup of rice/potato/what have you as your carb, the meat as your protein and oil as your fat. You don't need to be a mathematician to do this.
One exception might be a fatty cuts of red meat which would have a good serving of both fat and protein.
