Four calculators for the money Americans actually use

Each one answers a single question — what a 401(k) contribution becomes, how a high-yield savings balance grows, when a credit-card balance is gone, and what today’s dollar buys in ten years.

401(k) Growth

Project what a monthly paycheck contribution looks like after 10, 20, or 30 years.

High-Yield Savings

See how a starting balance and monthly contributions compound toward a goal.

Debt Payoff

Find out how long a balance takes to clear, and what it costs in total interest.

Inflation Calculator

Translate today's amount into tomorrow's cost, and see the purchasing power lost.

Numbers first, product pitches never

We don't sell funds, cards, or loans. Every calculator uses the same math you'd get from a U.S. brokerage worksheet — shown next to the result — so you can check it. The articles cover 401(k)s, Roth IRAs, FICA, and credit-card APRs the way they show up on an American paycheck, not as a classroom lecture.

Standard financial formulas, shown transparently in each result panel.

Articles written for a U.S. paycheck: employer match, Roth vs. Traditional, student loans.
