Full Privacy & No Sign-Up Required

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.

Instant AI-Powered Analysis

Our system uses advanced AI to scan your uploaded bank or credit card statements. It instantly identifies patterns and flags recurring transactions, accurately distinguishing between subscriptions and other regular bills. This happens in under two minutes, providing you with a complete, organized list of every active subscription and its annual cost without any manual tracking on your part.

Direct Cancel Links & Difficulty Scores

Once you unlock your results, each identified subscription comes with a direct link to its cancellation page. More importantly, each service is tagged with a "cancel difficulty score" based on known dark patterns—like hidden buttons or mandatory surveys—so you know exactly what to expect before you start the process, saving you frustration.

Exclusive AI Cancellation Agent (MCP Endpoint)

This exclusive feature sets Kill the Sub apart. Upon payment, you receive a personal MCP endpoint. You can share this with any AI agent and instruct it to cancel specific subscriptions for you. The agent knows industry tricks, understands which services require emails or phone calls, and can even draft and send cancellation emails from your Gmail, automating the most tedious parts.

Privacy-First, One-Time Pricing

Your financial data is handled with utmost security. Your statements are processed and immediately permanently deleted—nothing is stored. The pricing model is transparent and simple: a single, one-time payment of $3 with no subscription or hidden fees. We are so confident you'll save money that we offer a refund if you don't save more than $3.

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.

The Annual Financial Audit

Individuals or families conducting a yearly review of their finances use Kill the Sub to get a precise snapshot of all recurring software, entertainment, and service charges. It transforms a hours-long manual investigation into a two-minute task, identifying forgotten trials that converted to paid plans or services that are no longer essential, leading to significant annual savings.

Pre-Budgeting for a Large Purchase

Someone saving for a house, car, or vacation uses the tool to quickly find and eliminate "leaky bucket" expenses—small subscriptions that add up to hundreds of dollars per year. By canceling these unnecessary costs, they can reallocate that money directly into their savings goal, accelerating their timeline without impacting their primary income.

Simplifying Account Management for Busy Professionals

Professionals with limited time use the AI Cancellation Agent feature to delegate the tedious work. Instead of navigating multiple confusing cancellation flows, they simply tell their AI agent which subscriptions to cancel. The agent handles the web browsing, form filling, and email drafting, freeing up valuable hours.

Post-Trial Cleanup

Users who frequently sign up for free trials with credit cards use Kill the Sub to catch services that automatically convert to paid subscriptions. By uploading statements every few months, they can instantly see which trials have expired and turned into charges, allowing them to cancel immediately and avoid ongoing fees.

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 my financial data safe?

Yes. Privacy and security are fundamental. The moment you upload your bank or credit card statements (CSV or PDF), our system analyzes them. Immediately after analysis, your files are permanently and irrevocably deleted from our servers. We do not store your financial documents or transaction data.

What if I don't save more than $3?

We guarantee your savings. If our tool does not help you identify and cancel at least $3 worth of future subscription costs, we will refund your one-time payment. Simply contact our support with your results, and we will process the refund.

How does the AI Cancellation Agent work?

When you pay the $3 fee to unlock your full results, you gain access to a unique MCP endpoint. You can provide this endpoint to a compatible AI agent (like an advanced assistant). You then instruct the agent, in plain language, on which subscriptions to cancel. The agent uses its knowledge of cancellation dark patterns and methods to navigate websites or send emails on your behalf.

What file formats do you accept?

We accept both CSV and PDF statements from any bank or credit card provider. You only need to upload the last 2-3 months of statements for our AI to accurately identify recurring charges. The upload and analysis process is designed to take under 90 seconds.
