Assumptions
- Accrual period expressed as 12 month(s); partial months prorate.
- Compounding applied annually at 0.1075% per period. A partial compounding period prorates through a fractional exponent, which slightly understates the balance versus compounding each completed period and adding simple interest for the remainder; the tool never overstates.
