15-year vs 30-year mortgage comparison calculator. Computes monthly payment and total interest for both loan terms on the same purchase price and down payment, and reports the payment and lifetime-interest tradeoff between them.

Savings rate calculator. Divides the gap between monthly take-home income and spending by income to produce your personal savings rate as a percentage.
