Why we like it

Expression Calculator earns its spot for a specific, low-level task in After Effects: measuring how a property value moves before and after an expression, then letting you bake or reuse that value. It's a focused expression helper rather than a broad toolkit.

What is Expression Calculator?

Expression Calculator is a utility for After Effects that focuses on how a property value changes when an expression is applied. It calculates the difference value of a selected property before and after an expression, giving you the shift between the two states. The developer positions it as a way to design smarter After Effects templates that use expressions.

Beyond the difference calculation, the tool can bake a selected property with an expression at the current frame, and it can add a selected property's value to an expression. These three functions all operate on individual properties, keeping the scope tight around expression work.

Expression Calculator is at version 1.0, released on January 3, 2022 as its initial version. It lists compatibility with After Effects 2022, 2021 and 2020, plus CC 2019, CC 2018, CC 2017, CC 2015.3, CC 2015 and CC 2014. A demo video is available, and it appears in the aescripts library.

Who is Expression Calculator best for?

Frequently asked questions

Does Expression Calculator work with After Effects 2022?

Expression Calculator lists compatibility with After Effects 2022, 2021 and 2020, along with CC 2019, CC 2018, CC 2017, CC 2015.3, CC 2015 and CC 2014, so it covers a wide span of releases. If you run one of those versions, it should load without trouble. For versions newer than 2022 the compatibility isn't stated here, so check the developer's page before installing to confirm support for your current build.

Is Expression Calculator free to download?

Expression Calculator is listed as free in this catalog. Licensing terms can change over time, so for the current arrangement and any usage conditions it's best to check the developer's page directly. The tool reached version 1.0 as its initial release in January 2022, and that release covers the three functions described: calculating a property's difference value, baking a property with an expression at the current frame, and adding a property's value to an expression.

Can Expression Calculator bake a property at the current frame?

Expression Calculator can bake a selected property with an expression at the current frame, one of its three core functions. It also calculates the difference value of a selected property before and after an expression, and can add a selected property's value to an expression. These operations center on working with expressions on individual properties, which supports building After Effects templates that rely on expressions.

How does Expression Calculator help build expression-based templates?

Expression Calculator is intended for designing smarter After Effects templates that use expressions. It works property by property: calculating the difference value before and after an expression, baking a property with an expression at the current frame, and adding a property's value into an expression. A demo video is available. Version 1.0 was its initial release on January 3, 2022.
