Select a tool below to compute exact interest accrual, payoff schedules, and long-term compound growth.
Compound Interest & APY
Credit Card Debt Payoff
Mortgage Amortization

Analyze fixed-rate principal reduction against annual interest costs to compare 15-year and 30-year payoff schedules.
Transparent calculation methodology
Our money tools run on standard FDIC and Federal Reserve mathematical conventions. We apply exact compounding frequency formulas—whether daily, monthly, or annually—so your projected balance reflects real-world banking mechanics rather than marketing estimates.
Unlike commercial comparison sites, Capital & Wire never alters calculation outputs to favor sponsored banking products. Every tool operates independently without requiring sign-ups, personal data collection, or credit application redirects.
