A QUICK WALKTHROUGH
How to use this tool
- Choose single balance or dated segments and a 360, 365 or 366 basis.
- Enter balances, rate, days and every fee; enter zero for absent fees.
- Review each segment, fee subtotals and final repayment; save the complete report.
Scope
Simple interest only: balance × annual rate / 100 × days / basis. Segments must be chronological and nonoverlapping; gaps accrue no interest. Repayment uses the last segment balance, not the sum of balances. Fees are user contract values; no legal limits, bank defaults, compounding or effective APR. All money uses one currency.
Report
Exact fractions are retained for repeating decimals; no currency rounding.
