Key Takeaways
- TI-84 Plus Silver Edition at 69% off: The TI-84 Plus Silver Edition is the steepest discount in this group and the standard model for most college math sequences.
- CAS for calculus: The TI-Nspire CX CAS solves symbolic algebra, which calculus and engineering students lean on.

Summer is the quiet window for calculator shopping, which is exactly why it pays attention. Fall syllabi haven’t dropped yet, demand is low, and prices on the same TI models that spike every August are sitting well below their back-to-school highs right now.
This pool leans heavily on Texas Instruments because that is what college math departments standardize around. The TI-84 line shows up in nearly every algebra, statistics, and pre-calc course, and the discounts here run from roughly 22% up to 69%. A few renewed units stretch the savings further if you don’t mind refurbished hardware.
Our SlashSkill Picks below split into three groups: graphing calculators for the heavy coursework, scientific and financial models for specific majors, and a handful of desktop calculators for home offices and small businesses. Prices verified June 4, 2026.
Which graphing calculator is best for college?
For most college students, the TI-84 Plus is the safe answer because it’s the model professors build instructions around and it’s allowed on the SAT, ACT, and AP exams. Calculus and engineering students who need symbolic algebra should look at the Nspire CX CAS or TI-89 instead.
Texas Instruments TI-84 Plus Silver Edition

Texas Instruments TI-84 Plus Silver Edition Graphing Calculator – Handles Calculus and Engineering – USB Technology – 21 Apps
This is the model to grab if you want one calculator that lasts all four years. The TI-84 Plus Silver Edition runs the same operating system and apps as the standard TI-84, so every classroom walkthrough applies directly. At 69% off it’s the deepest cut in this group, and the USB port makes transferring programs and updates simple.
- Handles calculus and engineering coursework
- USB connectivity for updates and transfers
- 21 preloaded apps
Texas Instruments TI-84 Plus CE Coral

Texas Instruments TI-84 Plus CE Color Graphing Calculator, Coral (Metallic)
The TI-84 Plus CE is the newer, slimmer version with a color screen and rechargeable battery, and this Coral unit is a brand new model rather than renewed. It ranks #6 in its category for a reason: the color display makes graphs far easier to read than the older monochrome screens. Good choice for statistics and pre-calc where you’re plotting a lot.
- Color display
- Rechargeable battery
- Brand new, ranks #6 in category
Texas Instruments TI-Nspire CX CAS

Texas Instruments Nspire CX CAS Graphing Calculator (Renewed)
The Nspire CX CAS adds a computer algebra system, meaning it solves equations symbolically and factors expressions rather than just spitting out decimals. Calculus, differential equations, and engineering students get the most out of that. This one is renewed, so expect refurbished condition, but the CAS capability is what you’re paying for.
- Computer algebra system for symbolic math
- Color screen
- Renewed condition
Texas Instruments TI-Nspire CX II

TI-Nspire CX II Color Graphing Calculator with Student Software (Renewed)
The Nspire CX II is the current generation with a faster processor and the bundled student software for working on a laptop. It was added to this pool three days ago. If your program uses Nspire devices but you don’t need the CAS symbolic features, this color model covers graphing and statistics cleanly. Renewed condition here.

- Bundled student software
- Renewed condition
Texas Instruments TI-89 Titanium

Texas Instruments TI-89 Titanium Graphing Calculator (packaging may differ) (Renewed)
The TI-89 Titanium is the choice for heavy math and engineering loads, with symbolic algebra and 3D graphing built in. Note that many standardized exams ban the 89, so check your course rules before relying on it as your only calculator. This is a renewed unit, and packaging may differ from retail.
- Symbolic algebra and 3D graphing
- Renewed condition
- Banned on some standardized exams
Texas Instruments TI-83 Plus

Texas Instruments TI-83 Plus Graphing Calculator (Renewed)
The TI-83 Plus is the budget entry into TI graphing, and this renewed unit ranks #19 in its category. It handles algebra, trig, and intro statistics without trouble, though it lacks the color screen and faster processor of the CE models. A solid pick if a course specifically requires a TI-83 or you want to spend less.
- Covers algebra, trig, and intro stats
- Renewed condition
- Budget graphing option
What about scientific and financial calculators?
Scientific calculators cover algebra, trig, and stats at a fraction of graphing-model prices, and many intro courses only require one. Business and finance students need a financial calculator for time-value-of-money and amortization problems instead.
Texas Instruments TI-30XIIS
The TI-30XIIS is the #1 bestseller in its category and the workhorse for college algebra and statistics courses that don’t require graphing. It shows entries and results on a two-line display, runs on solar plus battery, and costs a fraction of any graphing model. If your syllabus only calls for a scientific calculator, start here.
- #1 bestseller in category
- Two-line display
- Solar plus battery power
Texas Instruments BA II Plus Professional

Texas Instruments BA II Plus Professional Financial Calculator
The BA II Plus Professional is the financial calculator for accounting, finance, and business majors, and it’s approved for the CFA exam. It handles net present value, internal rate of return, and amortization schedules that general calculators can’t. This one is sold by Amazon, so fulfillment and returns are straightforward.
- Time-value-of-money and amortization
- CFA exam approved

Canon P1-DHV-3 Printing Calculator
The Canon P1-DHV-3 is a printing desktop calculator that ranks #14 in its category and keeps a paper tape of every entry. That tape is the point for bookkeeping and retail, where you need to verify a long string of numbers. It’s sold by Amazon and prints in two colors for negatives and totals.
- Two-color paper tape printing
- Ranks #14 in category
- Sold by Amazon
Casio SL-300SV Desktop Calculator
The Casio SL-300SV is the pocket-size budget option, ranked #7, and it’s the cheapest item in this roundup.

Frequently asked questions
Which graphing calculator do most colleges require?
The TI-84 Plus is the most commonly required model across college algebra, statistics, and pre-calculus courses. It’s also permitted on the SAT, ACT, and AP exams. Calculus and engineering programs sometimes call for the Nspire CX CAS or TI-89 because of their symbolic algebra features.
What’s the difference between the TI-84 Plus and the TI-84 Plus CE?
The CE is the newer version with a color screen, a thinner body, and a rechargeable battery. The standard TI-84 Plus and Silver Edition use a monochrome display and AAA batteries. All three run the same core operating system, so classroom instructions apply to any of them.
Are renewed calculators worth buying?
Renewed units are refurbished and tested, which is why several here cost less than new models. The hardware and functions are identical, so they work fine for coursework. The main trade-offs are cosmetic wear and packaging that may differ from retail.
Do I need a graphing calculator if my course only lists a scientific one?
No. If the syllabus only requires a scientific calculator, the TI-30XIIS covers algebra, trig, and statistics at a much lower price. Buy a graphing model only when the course or exam specifically calls for one.
Discounts in this group run from about 22% up to 69%, with the steepest cuts on Texas Instruments graphing models and the smallest on the newer color CE units. Renewed listings stretch savings the furthest, while the scientific and desktop calculators are already cheap enough that the percentage matters less. June pricing on these is consistently softer than the August back-to-school spike.
The standout is the TI-84 Plus Silver Edition at 69% off, since it’s the model most college courses assume you already own and the discount is the largest here. For calculus-heavy majors, the Nspire CX CAS earns its renewed price through symbolic algebra. I’d skip the TI-89 Titanium unless your program requires it, because plenty of exams ban it and it leaves you needing a backup.
Expect TI prices to climb through July and peak in August as fall enrollment kicks in, so the case for buying now is straightforward if you know your fall courses. Casio and Canon desktop models tend to hold steady year-round, so there’s less urgency there. You can browse all deals for more office products as the summer slowdown continues.
