The magnetic flux cancellation on the Sun plays a crucial role in determiningthe manner in which the net magnetic flux changes in every solar cycle,affecting the large scale evolution of the coronal magnetic fields andheliospheric environment. We investigate, in this paper, the correlationbetween the solar magnetic flux cancelled at the equator and the solar magneticflux transported to the poles by comparing the net amount of magnetic flux inthe latitude belt 0${^{\circ}}$-5${^{\circ}}$ and45${^{\circ}}$-60${^{\circ}}$, estimated using synoptic magnetograms fromNational Solar Observatory at Kitt Peak, during Solar Cycles 21-24. We find agood correlation between the net flux in the latitude band0${^{\circ}}$-5${^{\circ}}$ and 55${^{\circ}}$-60${^{\circ}}$ for the Northernas well as for the Southern hemispheres. However, we find a poor correlation ifthe net flux for the Northern and Southern hemispheres are considered together.In addition, we investigate the correlation between the net flux cancelled atthe equator and the strength of solar polar field at cycle minimum, and find agood correlation between the two. We discuss the implication of the correlationof flux transported across the equator and to the poles that has an importantbearing in the estimation of the residual polar cap field strength at the cycleminimum. This can be used a predictive tool for estimating the amplitude ofsubsequent cycles and we use this to estimate maximum smoothed sunspot numbersof 77$\pm$5 and 85$\pm$5 for the Northern and Southern hemispheres,respectively, for the upcoming Solar Cycle 25.
