Generate a schedule

import { calculateAnnuity, toCSV } from 'jackpot-annuity';
const result = calculateAnnuity({
  total: '450M', payments: 30, growthRate: 0.05,
  discountRate: 0.04, timing: 'due'
});
console.log(toCSV(result));

Immediate versus ordinary payments

import { presentValue } from 'jackpot-annuity';
presentValue([10000, 11000], 0.1, 'due');      // 20000 cents
presentValue([10000, 11000], 0.1, 'ordinary'); // 18182 cents

Browser example

The repository’s examples/ directory contains a standalone form and table with CSV download. Serve the repository over HTTP, then open examples/. It imports ../src/index.js directly; no bundler or network API is needed.

python -m http.server 4187 --bind 127.0.0.1

Open http://127.0.0.1:4187/examples/. For published packages, pin a version when importing from a CDN to keep calculations reproducible across releases.
