- Rent vs Buy Calculator — mortgage, appreciation, and invested down payment vs. renting.
- Commute Cost Calculator — car, transit, rideshare, and bike compared side by side.
- Latte Factor Calculator — what a daily habit costs, and its future value if invested.
- Cashback Break-even Calculator — annual-fee card vs. a no-fee 1% baseline.
Also included at launch: bilingual English and Traditional Chinese pages, four supporting guides on installments, subscriptions, warehouse-club math, and rent vs. buy, plus a fully client-side privacy model — no calculator input ever leaves your browser.
