Best Calculator for AP Statistics (2027): Is Desmos Enough?
The calculator question changed for AP Statistics in 2027. The exam now runs in Bluebook with the Desmos graphing calculator built in, and scientific calculators are no longer allowed. Here is what you actually need, what is allowed, and when a handheld is still worth buying.
What is allowed on the 2027 AP Statistics exam
- The Desmos graphing calculator in Bluebook. It is built into the testing app. The desmos.com website and the Desmos phone app are not allowed.
- Up to two handheld graphing calculators from College Board's approved list. You don't need to clear their memory, and you can't share them.
- No non-graphing calculators. This is new for 2027. In past years a scientific calculator with statistics functions was acceptable for AP Statistics. Under the 2027 policy, only a graphing calculator with statistical capabilities or the built-in Desmos may be used.
Is Desmos enough?
For the exam, yes. We tested College Board's practice version of Desmos and it handles everything the revised course needs: one-variable statistics, the normal, binomial and t distributions, one- and two-proportion z procedures, one-sample, paired and two-sample t procedures, chi-square tests for homogeneity and independence, and least-squares regression with residuals. The AP Stats calculator guide shows the exact Desmos and TI-84 steps for each one.
There are still four good reasons to own a handheld:
- Class tests. Bluebook only exists on exam day. If your teacher gives paper tests in class without laptops, you need a calculator that works there. Ask your teacher what they expect.
- Your teacher teaches TI-84 keystrokes. Many AP Statistics classes teach on the TI-84, so notes, worked examples and review videos will match it.
- A backup on exam day. After the May 2026 exam, some students reported on Reddit that the inference tools were missing from their Bluebook calculator. We could not confirm those reports, but a familiar handheld removes the risk.
- Later courses. AP Precalculus and AP Calculus also use graphing calculators, and both include calculator sections.
The options compared
| Option | Cost | All AP Stats procedures? | Best for |
|---|---|---|---|
| Desmos in Bluebook | Free | Yes | Everyone on exam day. Practice in the College Board version. |
| TI-84 Plus CE | Mid-range | Yes | The default choice. Most classes and review materials use it. |
| TI-Nspire CX II | Higher | Yes | Students who already own one. Its menus differ from most class instruction. |
| Casio fx-9750GIII | Budget | Yes | The lowest-cost approved graphing option, if your class doesn’t depend on TI keystrokes. |
| Any scientific calculator | — | Not allowed in 2027 | Don’t buy one for AP Statistics. |
Texas Instruments also released the TI-84 Evo, which appears on College Board's 2026–27 approved list. It is new, and we have not tested whether its keystrokes match the TI-84 Plus CE instructions used in most classes and guides. Check with your teacher before choosing it over the Plus CE.
Our recommendation
- You have a laptop for class and your teacher teaches Desmos: buy nothing. Learn the Desmos steps in the calculator guide and practice in the College Board version.
- You want a handheld: get the TI-84 Plus CE. It matches what most teachers use and lasts through AP Precalculus and AP Calculus.
- You are on a tight budget: the Casio fx-9750GIII is an approved graphing calculator that does every AP Statistics procedure.
- You already own an approved graphing calculator: keep it. Whichever calculator you know best is the right one.

Before exam day
- Do at least one full practice set in the College Board practice Desmos, even if you plan to use a handheld.
- Check your handheld's model name against College Board's approved list, and charge it or replace its batteries.
- Learn the fallback for getting p-values from the distribution functions alone. It is in the calculator guide, and the one-page cheat sheet keeps every command in one place.
- Check every calculator answer by working one problem fully by hand with our step-by-step inference calculator. The exam rewards the reasoning, not just the number.
- Estimate where you stand with the AP Statistics score calculator, which uses the 2027 exam format.
Frequently Asked Questions
-
Do I need to buy a calculator for AP Statistics in 2027?
Not for the exam itself. The May 2027 AP Statistics exam runs in Bluebook with the Desmos graphing calculator built in, and that Desmos can run every procedure in the course. A handheld graphing calculator is still worth considering for class tests where you may not have a laptop, as a backup on exam day, or if your teacher teaches TI-84 keystrokes.
-
Can I use a scientific calculator on the AP Statistics exam?
No, not from 2027. College Board's calculator policy for the 2027 AP Statistics exam says nongraphing calculators are not allowed, even ones with statistics functions. You may use the built-in Desmos graphing calculator or an approved handheld graphing calculator.
-
How many calculators can I bring to the AP Statistics exam?
Up to two approved handheld graphing calculators, in addition to the Desmos calculator built into Bluebook. Calculators cannot be shared during the exam, and you do not need to clear their memory.
-
Is the TI-84 Plus CE allowed on the AP Statistics exam?
Yes. The TI-84 Plus CE is on College Board's approved graphing calculator list for AP Statistics, along with models such as the TI-Nspire CX II and the Casio fx-9750GIII. Always confirm your exact model against the current list on College Board's calculator policy page.
