Payment calculation differences

A detailed calculation guide is coming soon.

The short version: LoanAdmin today supports two loan types, chosen at creation and locked afterward:

  • Fixed-01 — flat simple interest; every installment is the same amount.
  • Amorti-01 — amortized; each installment splits principal and interest in a changing ratio.

If a schedule or balance doesn't match what you expected, first check which loan type was chosen in Loan detail. See also Creating a loan.
