We present ab initio calculations for {sup 3}H, {sup 4}He, {sup 16}O, and {sup 40}Ca based on two-nucleon low-momentum interactions V{sub lowk} within coupled-cluster theory. For {sup 3}H and {sup 4}He, our results are within 70 and 10 keV of the corresponding Faddeev and Faddeev-Yakubovsky energies. We study in detail the convergence with respect to the size of the model space and the single-particle basis. For the heavier nuclei, we report practically converged binding energies and compare with other approaches.
