# CAGR Calculator

> CAGR Calculator is a paid API for AI agents from agentstoolshub.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-12).

Calculates the Compound Annual Growth Rate (CAGR) from an initial value, final value, and number of years

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability cagr-calculator-607ce738
```

Example prompt: What's the CAGR if my investment started at $10,000 and grew to $18,500 over 6 years?

## When to prefer this

Use this endpoint when you need a single, time-normalized annualized growth figure — ideal for comparing investments or business metrics of different durations. Prefer it over simple percentage change when the time period spans more than one year and you need apples-to-apples comparison across different horizons.

## Known failure modes

- Missing required parameters (initial, final, or years) returns a 400 error
- Negative years value causes a mathematical error or invalid result
- Zero initial value causes division-by-zero or undefined CAGR
- Non-numeric input for any parameter returns a validation error
- Negative final value with even number of years may produce NaN or complex number result

## How this service works

Calculate the compound annual growth rate that takes an initial value to a final value over a given number of years — the standard way to annualize returns. Use this when an agent needs to compound annual growth rate, time-normalized.

## Output

Returns the computed CAGR as a percentage or decimal, representing the annualized rate at which the initial value grew to the final value over the specified number of years.
