Short answer

How can my AI calculate growth rates?

Your agent uses the calculate_increase_by tool to find the exact percentage change between two values. You just provide the numbers, and it returns the growth or interest increase. This breakdown shows the specific outcomes you'll get.

The outcomes

What you get from these calculations

The AI does the heavy lifting on the arithmetic.

PRECISION

Exact growth figures

The AI calculates the specific percentage difference between two data points. You get a single, accurate number instead of a manual calculation.

SPEED

Instant rate updates

When interest rates shift, your agent finds the new impact immediately. It processes the change without you needing a calculator.

ANALYSIS

Asset performance tracking

Compare current asset values against previous periods. Your agent identifies the percentage of growth or decline across your portfolio.

HUMAN

Strategic decisions

The AI provides the math, but you decide what those growth numbers mean for your strategy. You keep control over the final interpretation.

The workflow

What your AI does when the data arrives.

The AI acts as a math engine for your financial data.

  1. Identify the change

    Your agent looks at the two values you want to compare, such as an old interest rate and a new one.

    calculate_increase_by

  2. Run the math

    The agent invokes the calculation tool to find the exact percentage difference between those two points.

    calculate_increase_by

  3. Verify the result

    The AI checks the output against your original request to ensure the growth rate is accurate.

    calculate_increase_by

  4. Report the growth

    Your agent presents the final percentage or increase amount in plain text for you to read.

FAQ

How this task behaves

  • 01

    Can the AI change my actual bank balance?

    No. The AI only performs calculations based on the numbers you provide or the data it reads.

  • 02

    Does the AI handle compound interest automatically?

    No. The tool is designed for calculating specific increases and percentage changes between two values.

  • 03

    Can I use this with Claude or Cursor?

    Yes. Any MCP-compatible client works once you connect the engine through Vinkius.

  • 04

    Will the AI save my financial data?

    No. The AI uses the data to perform the calculation and then moves on. It does not store your financial records.

  • 05

    Can the AI write a full financial report?

    The AI can provide the numbers for a report, but you are responsible for writing and finalizing the document.
