Gravitational waves from compact binaries moving in inspiralling eccentric orbits are plausible sources of gravitational radiation for ground-based interferometric detectors, especially for detectors with good sensitivity at low frequency, such as VIRGO and Advanced LIGO. By using as target signals the current, most accurate post-Newtonian waveforms for inspiralling eccentric binaries, we evaluate the loss in signal-to-noise ratio if post-Newtonian templates for compact binaries in quasi-circular orbits were used. We explore how the loss in signal-to-noise depends on initial eccentricity, individual masses and post-Newtonian orders
