That web app looks like it'll be a much more comprehensive calculator in the future. Ours is quite limited: the periods are pre-defined and the top-ups are on a weekly basis only.
But if you have any ideas after trying the tool, let me know. No promises, but I'll consider any suggestions related to the APR calc :)
Yes, that's true. Your bot calculator is really cool too. Weekly is okay at least we can have an idea of how the compounded interest would be. I will let you know for sure :) Thank you.
