I have just spent half an hour with a calculator, and I'm still not sure I have an answer.

Does anybody have any thoughts on this, good links on how to calculate, or other suggestions?

We have a 13 foot round pond, 2 feet deep, 5 adult goldfish about 6 inches long. And fry!

So by metric system your pond is about 4 meters in diameter & 60 cm in depth.

That means it's capable of holding 7500 litres of water. Let's make it 7000 litres to be realistic. Meaning it can hold about 1800 gallons.

Well, maybe my pond has more gallons in it than I thought. But it is probably less than 1800, though, because there are rocks all around the edge, taking up space, and also the sides slope in a bit. But it does seem like it's more than 1300 gallons. That's really good news.

So next question is, how many goldfish could I have in the pond? I'm so worried we have waaaaay too many fry.
