Home loan repayments - principal to interest ratio

I’ve been paying down hard on the loan for some time now and think it’s time to slow down and do other things with my money. This has got me thinking as to how much I should be paying. Is there any advice as to the amount you should pay relative to the interest? I.e. aim for 75% principal, so if interest is $500 pm, pay $2000 pm.

I suspect the answer is that it depends and it is a personal choice, just wondering how others approach this.
