Crate amortization_schedule 

amortization-schedule

Loan amortization math: fixed-rate monthly payment, per-period interest/principal split, remaining balance, and lifetime interest. Pure Rust, no deps. Same math behind the AssetLoanCalculator amortization tool.

use amortization_schedule::{monthly_payment, total_interest};
let p = monthly_payment(100_000.0, 0.07, 360); // ~665.30
let ti = total_interest(100_000.0, 0.07, 360);
assert!(p > 0.0 && ti > 0.0);
