Having trouble calculating swap. Very noob question but I was hoping I could find answers here.

So I'm trying to calculate the interest gained from swap with my broker. Let's say I have a 5000 USD account and I open a position with 500 USD on AUD/JPY. 1 lot is 100,000 units. positive buy rollover on my brokers website says 0.00328 or 3.28 buy points. If my leverage is 1:100, and I buy the pair right before swap is accrued what would be the interest gained?
