How this service works
ROI calculator - return on investment percent, gain, multiple and annualized return from amount invested and returned
Output
Returns a JSON object containing: roi_percent (ROI as a percentage), gain (absolute dollar gain), multiple (return multiple), invested amount, returned amount, and optionally annualized_return_percent and years if a holding period was provided, along with a checked_at timestamp.
Example use cases
Evaluating a stock investment return
“I bought $10,000 worth of stock and sold it for $14,200 two years later. What's my ROI, how much did I gain, and what was my annualized return?”
Comparing real estate deal performance
“We put $150,000 into a property and exited for $310,000 after 5 years. Can you calculate the ROI percent, the gain, the multiple, and the annualized return on that deal?”
Checking a startup investment outcome
“I invested $5,000 in a startup and just received $47,500 back. What's my return on investment percentage and what multiple is that?”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/calc/roi?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need quick, structured ROI metrics — percent return, gain, multiple, and annualized return — from a simple invested/returned pair, especially when you want a single API call with a micropayment model rather than building the math yourself or calling a heavier financial analytics service.
Side effects
- Missing required 'invested' or 'returned' query parameters returns an error
- Non-numeric values for invested or returned cause a parse failure
- Division by zero if invested is 0
- years parameter provided as non-numeric string may cause calculation error
- Payment failure or expired x402 authorization returns 402 Payment Required
