# Available calculators

> Every calculator offered by Calculators by Symmetry (CBS), with a one-line description and the integration paths that support it.

This is the full list of CBS calculators. Most are available on both [integration paths](/cbs/overview/choose-path) (as an embeddable widget and through the API); exceptions are noted.

¹ **457** has no dedicated widget and is not a listed API endpoint. It's reachable only through the API's model, print, and state-parameter flows when a 457 calculator type is supplied.

<Note>
  In the API's `/calculators` listing, the two bonus calculators are named `bonus-percent` (flat bonus) and `bonus-agregate` (aggregate bonus); the widget and URL names are `flatbonus` and `agbonus`.
</Note>

<Note>
  Supplemental bonus methods are state-by-state compliant. Some states do not support the flat bonus (percent) method. For example: AZ, CT, DE, HI, LA, MA, MS, NJ, UT, WY, DC, and PR.

## Multi-calculator

In CBS, **multi-calculator** is a **widget-only** layout feature, not a calculation type. It places up to four calculators side by side on one page and includes a copy button to reuse inputs across them. It has no API endpoint. See [Multi-calculator](/cbs/widgets/multi-calculator).

## Calculation methods

The withholding method varies by calculator (annualized, flat, or current aggregation). For the per-calculator breakdown, see [Calculation methods by calculator](/cbs/core-concepts/calculation-methods-by-calculator).
