Let our expert reviewers help you pick the best scientific calculator. First, we interviewed three veteran math and science teachers with a combined 37 years of teaching experience to get their insights. Then we asked our readers to share their real-world experiences—which calculators worked best for middle schoolers? High school? What about the SAT/ACT? Here are the ones we think are best.

FYI: We've been reviewing and rating products for the home and families since 1994. We don't take money or freebies from the brands we review. Our work is 100% reader-supported!


Best Tried & True Brand

Great for middle schoolers
We love this calculator's ease of use—perfect for algebra, statistics, geometry or general science. Also nice: approved for use by SAT/ACT.

Best Tried & True Brand: Texas Instruments TI-30XIIS Scientific Calculator

When it comes to scientific calculators, one brand came up time and time again in our research: TI. This model is recommended by the math and science teachers we interviewed for this article—and it is allowed by the ACT and SAT tests.

Of course, when you hear “Texas Instruments” you might think this is going to be a pricey purchase . . . but there is good news. This calculator is actually among the more affordable options out there.

What We Liked

• Lots of short cuts. But you have to make the effort to learn them.

• Easy to switch from degree to radian mode.

• Great for middle schoolers.

• Words and symbol keys are good size.

• Affordable.

What Needs Work

• Button lag. Sometimes when you push a function button, there is a lag before the next screen pops up.

• Instructions could be more detailed.

• Could be easier to read, especially when lying flat.

Best For High School

Excellent for chemistry, statistics
The easy scientific notification is the star feature here, but we also like the ability to enter more than one calculation at a time. Easy to use, even though the buttons are a bit small.

Best For High School: Texas Instruments TI-30XS MultiView Scientific Calculator

Even though it is bit more expensive, we would recommend this calculator—especially for high schoolers. The 2-line display and ability to enter more than one calculation make this a good bet, especially for classes like statistics. 

What We Liked

 Easy to use.

• Great for tests.

• Excellent for statistics, but also algebra, biology and chemistry.

• Affordable.

What Needs Work

• Smaller buttons.

• Can eat through batteries quickly, even though it also works on solar.

Best for Engineers

Gets the job done
This calculator is great for programming—and we like the cheat sheet for different functions built into the cover. Perfect for engineers or high schoolers taking trigonometry.

Best for Engineers: Casio fx-115ESPLUS2 2nd Edition, Advanced Scientific Calculator

When researching scientific calculators, we realize one size rarely fits all. If you are an engineering student starting college, you may want something designed for these classes. In that case, we like the Casio fx-115ESPLUS2. Yes, that is a mouthful, but this is an excellent calculator, with vector operations, complex numbers and more.

What We Liked

• Great for programming.

• Easy to use . . . if you are an engineering student!

• Great for trigonometry, chemistry and other basic science classes.

What Needs Work

• Instructions could be better, even though there is a cheat sheet for different functions on the inside cover.

Best For Test Taking

Easy to use
We like this excellent calculator for basic high school algebra and even some entry-level college courses. Nice bang for the buck.
$12.59

Best For Test Taking: Casio fx-300ESPLUS2 snd Edition, Standard Scientific Calculator

This calculator is similar to the model we discussed above, but has less functionality (the 115 model has matrix operations, stored constants and number conversion—the 300 model here lacks those features). That said, this is still a good bet, especially for high schoolers taking basic chemistry or algebra classes. And since this model is less money, that might be a good option.

What We Liked

• Affordable.

• Good for exams.

• Versatile with linear regression.

• Good for general math like pre-algebra, algebra 1 and 2, geometry and more.

What Needs Work

• Lacks vector operations, which are more common in college-level courses.

How We Pick Products To Recommend

We often turn to our readers (3 million strong!) to find products to recommend. We ask our parent readers for their favorites and consider their real-world experiences in our recommendations.

When we test a product, we always purchase it with our own monies. We do not take free samples, as we believe that compromises our independence.

We also fact check manufacturer information with our own measurements. If a maker claims a product weighs X pounds, we will weigh it to make sure. If the battery life is supposed to be six hours, we will see how it stands up in the real world.

In some cases, we will do interviews with experts in the field to get additional feedback on products.

To get hands-on time with products, we regularly meet one-on-one with gear companies and even tour manufacturing facilities. (When we do this, we pay our own travel expenses).

Why Trust Us

We’ve been rating and reviewing products for the home and families since 1994. We do extensive research, evaluating products with an eye toward quality, ease of use and affordability.

We make our living from affiliate commissions, but we always recommend what we think are the best bets for our readers (not the ones that are the most expensive). We are always looking for products that offer the best bang for the buck.

Our independence is a key reason why we have been doing this so long. As we mentioned above, when we purchase a product for hands-on testing, we do so with our own money.

Here’s another key point: we don’t take money from the brands we review. No free samples, no sponsors, no “partnerships.” Our work is 100% reader-supported!
