Nice kata. properly graded at 6 kyu, clear, concise description, and no long, annoying and unnecessary storyline.

Same here, tryed to figure out the formula and the example numbers don't match

I really enjoyed that one. Very useful code in the solution.

Even though this is an easy kata, it was actually pretty good.

I think I know what you were doing wrong cause I did the same thing. You have to make sure you're using the newest interest amount and not from the initial principal amount.

smth wrong with test. I have an error (expected 14 but it was 17), I run the same solution it IntelligIdea and it was 14. //Java

you calculate the tax based on the interest earned for that year

Maybe give the formulae as they require prior knowledge which has nothing to do with coding, or suggest people google as a legitimate coding skill.
Principal * interest rate = interest
interest * tax rate = tax
Principal + interest - tax = investment return
investment return is next year's principal

Tax is also only calculated on income earned over a certain dollar amount. This is just a bad problem.

I couldn't solve this problem because I don't know how to calculate tax.
But I learned, tax should have been calculated for how much money you earn from interest,
not for how much money you have.
