Worked out from Standard annuity-immediate payment formula, PMT = P i / (1 - (1+i)^-n) and 1 other source.

How this is worked out

5 steps

Each period, interest = outstanding balance x 0.541667%; the rest of the payment reduces principal.
Payment 1: 135.42 interest and 22.6 principal.
From payment 233 onwards more of each payment goes to principal than to interest.
The balance is half repaid by payment 257.
Year 1 ends with 24720.53 outstanding, 1.12% of the loan retired.
