This calculator is free and always will be. There is no login, and we don't sell advertising against these pages.
If your build comes out over GVM, or close enough to it that a GVM upgrade is worth considering, we offer to pass your details to suspension and GVM specialists. Those businesses pay us for the introduction. You are never charged, and you only ever go on that list by filling in the form yourself.
It does not buy a number. No manufacturer, installer or advertiser can change a kerb weight, a GVM or a payload result on this site. The figures come from the vehicle manufacturer's spec sheet and nowhere else, and a business that pays us for referrals has no say in whether your result comes back green or red.
We think that's worth stating plainly, because a calculator that quietly nudges you toward an upgrade you don't need would be worth exactly nothing.
CheckMyGVM is run by a small Australian team that also operates other automotive websites. Those sites are run separately and no commercial relationship on any of them affects the figures published here.
