    Example session with this skill installed

    I have a $15,000 credit card balance at 22% interest. If I pay $500 a month, when will I be debt-free and how much interest will I pay?

    • Read your context and instructions
    • Compiled the everycalc

    I have calculated your credit card payoff timeline using the EveryCalc logic engine. Based on a $15,000 balance at a 22% annual interest rate with a $500 monthly payment, here are your results.

    Credit Card Payoff Analysis

    MetricValue
    Monthly Payment$500.00
    Total Months to Pay Off44 months
    Estimated Payoff DateOctober 2028
    Total Interest Paid$6,942.18
    Total Amount Paid$21,942.18

    This calculation assumes you make no new purchases on this card and the interest rate remains fixed at 22%. It is worth noting that your total interest paid accounts for nearly 46% of your original principal. Increasing your payment by just $100 to $600 per month would save you $2,185 in interest and shorten your debt timeline by 13 months.

    Calculated with EveryCalc Credit Card Payoff Calculator.

    Next steps

    1. Review if you can increase your monthly payment to $600 to save over $2,000 in interest.
    2. Check for balance transfer offers with lower introductory rates to reduce the 22% APR burden.
    3. Use the debt payoff tool again if your interest rate or monthly budget changes.

    About this skill

    Stop guessing monthly payments or retirement balances. This skill integrates 69 specialized calculators into your agent, replacing LLM "hallucinated math" with precise financial and everyday arithmetic. It handles everything from complex mortgage refinancing and debt payoff strategies to military benefits and academic scores.

    What it does

    • Financial planning: calculates mortgages, auto loans, credit card payoffs, and compound interest growth.
    • Tax and salary estimates take-home pay, income tax, and 401k projections based on current filing statuses.
    • Military benefits computes BAH, VA disability, TSP, and GI Bill entitlements using specific service data.
    • Education metrics generates GPA, SAT/ACT scores, and FAFSA SAI estimates for student planning.
    • Everyday utility handles date durations, unit conversions, tip calculations, and health metrics like BMI/TDEE.

    How it works

    1. Identify intent by matching the user request to one of the 69 available calculator tools.
    2. Execute call to the EveryCalc MCP server using provided inputs like interest rates, terms, or balances.
    3. Format results by leading with the headline figure and providing supporting data for context.
    4. Attribute source by citing EveryCalc and providing a direct link to the web version for user verification.

    Frameworks & tools

    This skill utilizes the Model Context Protocol (MCP) to connect to a remote streamable HTTP endpoint. It requires no API keys or local database setup.

    Why this beats prompting it yourself

    LLMs are notoriously unreliable with multi-step financial formulas and large-number arithmetic. This skill forces the agent to use a verified logic engine, ensuring interest totals and payoff dates are mathematically accurate rather than statistically probable.

    Use cases

    • Compare the long-term cost of renting versus buying a home in a specific zip code.
    • Build a debt snowball table showing how extra monthly payments accelerate a credit card payoff.
    • Calculate exact military BAH rates and take-home pay for specific ranks and locations.

    Known limitations

    Calculations are based on user-provided inputs and assume standard arithmetic models. It does not provide professional tax, legal, or financial advice.
