Does cooking oil count in your calories?
Yes, and it is usually the biggest single item in the dish. Oil is pure fat at about 884 kcal per 100 grams[1], ghee is close behind[2], and one level tablespoon is near 120 kcal[1]. The workable method is to log the fat that went into the whole pot once and divide it by the servings, rather than argue about it at every meal.

Yes, and it is usually the largest number in the pan
Cooking fat is the most under-recorded item in a home kitchen. It is poured rather than portioned, it disappears into the food, and it leaves nothing on the plate to remind you it was there. It is also, gram for gram, the most energy-dense thing you will cook with: fat carries about 9 kcal per gram, against 4 for protein and carbohydrate[3]. A dish can be built entirely from vegetables and still be the heaviest meal of the day because of what went into the pan first.
So the answer to the question is a flat yes. Oil and ghee count, they count a lot, and a food diary that logs the chicken and the rice but not the fat they were cooked in is not a food diary of that meal.
What a spoonful actually is
Vegetable and olive oil are essentially pure fat: 100 grams of oil is 100 grams of fat and about 884 kcal[1]. Ghee, samna and clarified butter are barely different, at roughly 99.5 grams of fat and 876 kcal per 100 grams[2]. Nothing else in an ordinary kitchen is close.
A level tablespoon of oil weighs about 13.5 grams, which puts one spoon near 120 kcal[1]. That is the figure worth memorising, because almost nobody cooks with one spoon. Two generous spoons of samna stirred through a pot of vegetable stew is in the region of 240 kcal[2] before a single ingredient is counted, and a shallow layer covering the base of a wide pan is several times that.
Why the app and the kitchen disagree
A database entry for a cooked dish is a recipe someone else wrote. It assumes a certain amount of fat, and your pot assumes yours. The gap between a cautious restaurant recipe and a generous home one is almost entirely fat, which is why two plates of the same dish can differ enough to matter while both entries are honestly labelled.
The second gap is that not all of the fat in the pan ends up inside you. Some stays behind in the pan, some stays in the frying oil, and some is poured off with the liquid. How much varies with the food, the temperature and how long it cooks, so there is no honest single number for it. The practical conclusion is not to guess a correction, but to log what you added, keep the method consistent, and let your own weight trend over several weeks tell you whether your estimate was close.
How to log it without weighing every drop
Log the pan, not the plate. Add up the fat that went into the whole pot, log it once, and divide it by the number of servings the pot produced. This takes one entry per dish instead of an argument at every meal, and it is far more accurate than the alternative, which is leaving it out.
Pour with a spoon rather than straight from the bottle for a week. Most people discover their normal pour is two to three times what they assumed, and after a week of seeing it they no longer need the spoon. If you cook the same few dishes repeatedly, measure each one once and reuse that figure; being consistently slightly wrong is useful, because a consistent error still shows a real trend, while a random one shows nothing.
Should you cut the oil?
Not to zero. Dietary fat is a requirement, not an indulgence, and expert consultations put a reasonable intake at 20 to 35 per cent of total energy[4]. Below that range you are cutting into fat-soluble vitamin absorption and, in practice, into how satisfying your food is. Fat also does more for the taste of vegetables than anything else available, and a vegetable dish you enjoy is worth more than one you abandon.
What is worth changing is the pour you never see. Measure it, cook with a lid and less liquid loss, grill or oven-roast instead of shallow-frying when the dish allows, and spend the fat you do use on the things that need it. If you want to see how fat fits into the rest of the day's budget, the guide on how to split your calories into carbs and fat covers the arithmetic, and how your daily calories are calculated explains where the budget itself comes from.
