  We show how to compute the Tamarkin-Tsygan calculus of an associative algebra
by providing, for a given cofibrant replacement of it, a `small'
$\mathsf{Calc}_\infty$-model of its calculus, which we make somewhat explicit
at the level of $\mathsf{Calc}$-algebras. To do this, we prove that the operad
$\mathsf{Calc}$ is inhomogeneous Koszul; to our best knowledge, this result is
new. We illustrate our technique by carrying out some computations for two
monomial associative algebra using the cofibrant replacement obtained by the
author in 1804.01435.
