Loan Payment Calculator

For balance P, monthly rate r = annual percentage / 1200 and n = years × 12, payment is P × r / (1 − (1 + r)^−n). At zero interest, payment is P / n.

Travel Budget Calculator

Trip budget equals daily cost per traveler × days × travelers. The per-traveler result is daily cost × days; only costs included in the daily amount are counted.

Mortgage Calculator

Financed principal = home price − down payment. For monthly rate r and n payments, payment = principal × r / (1 − (1 + r)^−n), or principal / n at zero interest.

Adjustable Rate Mortgage Calculator

This tool compares monthly interest, not amortizing payments: balance × current annual rate / 1200 versus balance × adjusted annual rate / 1200.

Interest Only Mortgage Calculator

Monthly interest-only payment is loan amount × annual percentage / 1200. Interest during the entered period is loan amount × annual percentage / 100 × years.

Balloon Mortgage Calculator

The modeled monthly payment is interest only: principal × annual percentage / 1200. The displayed balloon balance equals the original principal, with no amortization modeled.
