Pumpkin Pie Calories Calculator: 3 Slices, 960 kcal
On the defaults — 3 slices at 320 kcal a slice — the plate totals 960 kcal, 3840 kcal a dozen. This is the pumpkin pie calories tool: slices eaten times calories a slice is the total, and a dozen is always twelve times the per-slice figure — a pie guessed from the tin alone tells you nothing until the slices actually eaten are counted.
What does 960 kcal mean?
It means three slices at 320 kcal a slice carry nine hundred and sixty kilocalories, which is 3840 kcal for a full dozen slices. The count sets how many slices the calories ride on, and the per-slice figure sets what each one carries: one more slice at the same recipe adds 320 kcal without changing the recipe, and a richer recipe adds calories to every slice without adding a single extra one. The only judgement is the per-slice figure itself — a thin slice and a wide wedge from the same pie are not the same slice, and the recipe is the only honest source for it.

| Output | Formula | What it means |

| Total | slices × calories a slice | 960 kcal — 3 × 320. |
| A dozen | total ÷ slices × 12 | 3840 kcal — 960 ÷ 3 × 12. |
Three things to check before you trust the number
First, check the count honestly: 3 slices must be slices actually eaten, not slices baked, gifted, or left on the plate — a slice counted that was given away adds calories that were never eaten. Second, check the per-slice figure against the recipe: 320 kcal must be the slice actually eaten, not a lighter cousin from a different recipe — cream, crust, and sugar all lift the figure, so mixing recipes breaks the total. Third, check the dozen against the batch: 3840 kcal must be twelve slices at the same recipe, not a dozen mixed from different pies — a mixed dozen is twelve different figures wearing one total.
Worked example
3 slices, 320 kcal a slice. Total: 3 × 320 = 960 kcal. A dozen: 960 ÷ 3 × 12 = 3840 kcal. In practice that means a generous plate carries about as much as a full meal, and the 320 kcal per-slice figure is the one to set against other holiday desserts, since one slice is the unit every dessert shares.
Every branch, checked
At 5 slices instead of 3, the total rises to 1600 kcal — 3840 kcal a dozen. At 380 kcal a slice instead of 320, the total rises to 1140 kcal — 4560 kcal a dozen. At 1 slice instead of 3, the total falls to 320 kcal — 3840 kcal a dozen. At 12 slices instead of 3, the total rises to 3840 kcal — 3840 kcal a dozen.
The reverses, worked backwards
The slices behind 960 kcal are 3: at 1 slice the total is 320 kcal; at 6 slices it is 1920 kcal. The calories behind 960 kcal are 320 a slice: at 260 kcal a slice the total is 780 kcal; at 380 kcal a slice it is 1140 kcal — the per-slice figure never touches the count, only what each slice carries.
What the defaults assume
The defaults assume 3 slices at 320 kcal a slice, a typical pumpkin pie slice. They do not assume a particular recipe, brand, or slice width — so treat 960 kcal as the planning total for three 320 kcal slices, and check it against the recipe or label before logging it as exact.
Who uses this
- A Thanksgiving host costing the table: the 960 kcal is the figure to set against the day’s budget.
- Someone comparing holiday desserts: the per-slice figure compares pumpkin pie fairly with cookies and gingerbread.
- A person tracking daily intake: the total adds the plate to the day exactly.
- A baker planning a pumpkin pie table: the dozen figure prices the whole batch exactly.
Accuracy & limitations
The arithmetic is exact for the inputs entered; the judgement is the slices actually eaten and the true per-slice figure for that recipe. Real pumpkin pie varies with slice width, crust, cream, and sugar — so treat 960 kcal as the planning total for 3 slices at 320 kcal a slice, and check it against the recipe or label before logging it as exact.

Frequently asked questions
How many calories are in a slice of pumpkin pie?
320 kcal on the defaults, a typical pumpkin pie slice — the real figure depends on the recipe, so check the recipe for the slice actually eaten.
How many calories are in 3 slices of pumpkin pie?
960 kcal on the defaults: 3 × 320 kcal a slice = 960 kcal in all.
How many calories are in a dozen pumpkin pie slices?
3840 kcal on the defaults: 12 × 320 kcal a slice = 3840 kcal a dozen.
Why does the per-slice figure matter so much?
Because it multiplies every slice: at 380 kcal a slice the same 3 slices total 1140 kcal, while at 260 kcal they total 780 kcal.
How do I keep the total down?
Eat fewer or bake lighter: 1 slice totals 320 kcal, and a 260 kcal recipe brings 3 slices down to 780 kcal.
Does cream change the calories?
Yes: cream, crust, and sugar all lift the per-slice figure, which is why the recipe actually eaten is the only honest source.
