Full Privacy & No Sign-Up Required

Your financial data stays on your device. The calculator runs 100% in your browser; we never see, store, or transmit your personal inputs or results. There is no requirement to create an account, submit an email, or view ads, ensuring complete confidentiality.

Mobile-First, User-Friendly Design

Access and use the tool seamlessly on any device. The interface is optimized for smartphones and tablets with a clean, intuitive layout, large input fields, and touch-friendly controls, making it easy to calculate on the go.

Real-Time Filing Surveillance

Our system monitors all 535 members of Congress around the clock, automatically collecting every new trade disclosure the moment it is published to government databases. This ensures no high-signal trade slips through the cracks, giving you access to information as soon as it becomes public record.

Proprietary Signal Scoring

Not every congressional trade is meaningful. We analyze and score each trade as Low, Medium, High, or Critical based on key factors like the politician's committee jurisdiction, the position size, and political timing. This filters out the noise, so you only see trades with a strong insider signal.

Plain-English Trade Analysis

We provide clear, actionable context for every high-scoring trade. Our analysis explains why the trade matters, detailing the committee involvement, sector relevance, and potential market impact. You get the "why" behind the trade, not just raw data.

Curated Alert Feed & Email Notifications

You don't need to hunt for information. Our platform features a curated feed of the best trades, and we send instant email alerts for high-score trades directly to your inbox. This allows you to act on opportunities quickly, without constant manual checking.

Comparing Bank CD Offers

Use the calculator to input terms from different banks—like Chase, Wells Fargo, or Navy Federal—to instantly compare which CD offer will yield the highest return. This allows for an apples-to-apples comparison before you open an account.

Planning for Specific Financial Goals

Project how much your savings will grow in a CD to meet a future goal, such as a down payment, vacation fund, or major purchase. Adjust the initial deposit, term, and rate to see various scenarios and create a solid savings plan.

Understanding Compounding Impact

See the tangible difference that compounding frequency makes on your total interest. Switch between daily, monthly, and annual compounding with the same APY to visualize how more frequent compounding accelerates growth.

Evaluating Early Withdrawal Scenarios

Model the potential penalty impact of cashing out a CD early. By calculating the projected maturity value, you can better assess if accessing your funds before the term ends is financially worthwhile despite penalties.

Kapitol.ai is an intelligence platform that tracks, analyzes, and delivers the stock trades of all 535 members of the U.S. Congress. While politicians are legally required to disclose their trades under the STOCK Act, these filings are buried in complex government databases, making them nearly impossible for the public to find and act on. Kapitol.ai solves this by monitoring every filing in real-time, scoring each trade based on the strength of its insider signal, and providing plain-English analysis. The platform filters out the noise to highlight only the highest-conviction moves from committee chairs and key members, allowing investors to follow the "smart money" in Washington. It is designed for retail investors, traders, and anyone looking to gain an informational edge by leveraging the legally disclosed, market-moving trades of Congress members who consistently outperform the market.

What is the difference between APY and APR in the calculator?

APY (Annual Percentage Yield) is the correct rate to use for CDs as it includes the effect of compounding interest. APR (Annual Percentage Rate) typically does not include compounding. Our calculator is designed to work with APY to give you an accurate projection of your actual earnings.

Is the CD Calculator really free to use?

Yes. The CD Calculator is completely free. There are no costs, no required registrations, and no advertisements blocking functionality. It is a public tool designed to provide transparent financial information.

Can I use this calculator for CDs from any bank?

Absolutely. The calculator is compatible with the terms and compounding methods used by all major US banks and credit unions, including Bank of America, Citibank, Chase, and Wells Fargo. Simply enter your specific APY and term details.

How accurate are the results from this calculator?

The results are highly accurate estimates for informational purposes. They use standard financial formulas for compound interest and round to the nearest cent. For your exact final maturity value, always refer to your bank's official documentation, as they may use slightly different rounding methods.

Is this insider trading?

No. Members of Congress are legally allowed to trade stocks based on their non-public knowledge, a loophole largely upheld by the STOCK Act which only requires disclosure. Kapitol.ai simply aggregates and analyzes these legally mandated public disclosures, giving you access to information that is already public but notoriously difficult to find and interpret.

How accurate is the track record?

The track record is based solely on publicly disclosed congressional trade data. Our reported 68% win rate and +19% average return are calculated from the 157+ trades we have curated and scored since January 2025, comparing the stock's performance against the trade disclosure date. Past performance does not guarantee future results.

What is a "Critical" signal trade?

A Critical signal is our highest score, assigned to trades that show the strongest insider conviction. These typically come from Committee Chairs or key members with direct jurisdiction over the traded company's sector, involve maximum position sizes for that politician, and occur during relevant political timing windows.

Is there really a free account?

Yes. We offer a free account that provides access to curated trade alerts and basic platform features. No credit card is required to sign up. This allows you to experience the value of the service and see actual trade previews before considering any premium upgrade.
