Both break even at 12 years, so the financial timing is a wash. The difference is in what happens after that, and in how exposed each role is to automation. Repayments differ too — £98,658 over the life of the Geography / Environmental Science loan against £85,904 for Biosciences. The higher figure is usually the higher earner, not the worse deal.
This compares money only. It says nothing about whether you would be any good at either, or want to spend a career doing it — and the no-degree comparison is an estimate, which is the figure both verdicts are most sensitive to.
These use default costs. Your tuition, maintenance, repayment plan and where you land in the earnings range all move the answer.
