    for month in range(months):
        borrowed -= repayment
        borrowed *= (1 + interest / 12)
    print(borrowed)

With a little cleaning and some proper variable names the for loop is perfectly clear, but I do respect wanting to clean up code. I like my code neat too, but never at the cost of speed. Try it for yourself. Run both for 100K months.

I completely agree with you. But maybe a beginner would read this and ask why the 'month' ('m' in my case) variable exists.
