How this service works
Return on average assets - Weighted result mean: Calculate a mean of up to 200 results using supplied nonnegative weights; not a pooled accounting ratio. Metric: Return on average assets. Supplied figures only; returns JSON with formula, units and limitations. One of 50 calculators with 20 analysis modes. No live feed, financial advice or trade execution. 0.01 USDC includes one bounded weighted result mean report.
Output
A JSON object containing the weighted mean ROAA value computed from the supplied rows, along with the formula used, units, and a limitations notice clarifying this is a statistical weighted mean rather than a pooled accounting ratio.
Example use cases
Quarterly ROAA trend aggregation
“I have ROAA data for 6 quarters — net incomes are 5000, 5200, 4800, 5500, 5100, 5300 and average assets are 80000, 82000, 79000, 85000, 83000, 86000. Weight the more recent quarters more heavily using weights 1, 1, 2, 2, 3, 3 and give me the weighted mean return on average assets.”
Multi-subsidiary asset return summary
“We have 5 subsidiaries with net incomes of 1200, 3400, 800, 2100, 4500 and average assets of 15000, 42000, 9000, 28000, 60000. Weight them by their asset size so larger subsidiaries count more — weights 15000, 42000, 9000, 28000, 60000 — and compute the weighted mean ROAA.”
Year-over-year profitability comparison
“Calculate the weighted mean ROAA for two companies over three years each: Company A has net incomes 2000, 2200, 2400 with average assets 30000, 31000, 32000, and Company B has net incomes 1800, 2100, 2500 with average assets 28000, 29500, 31000. Use equal weights of 1 for all rows and show me the formula and units in the result.”
Technical details
Endpoint
POSThttps://market.datapackvibe.com/x402/assistant-finance-return-assets-weighted-mean?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a statistically weighted mean of ROAA across multiple discrete observations (periods, entities, or scenarios) and want to assign custom importance weights to each row. It is not a pooled accounting ratio and does not fetch live financial data — use it when you already have net income and average assets figures and need a weighted aggregation with formula and units returned in a structured JSON report.
Side effects
- Fewer than 2 rows supplied — minimum of 2 rows required
- More than 200 rows supplied — exceeds maximum item limit
- average_assets value of zero or negative — field requires exclusive minimum > 0
- Weights array length does not match rows array length — mismatch causes validation error
- Net income or average assets outside allowed range of ±1 trillion — values rejected
- Negative weight supplied — weights must be nonnegative
- Payment not included or insufficient — x402 payment of 0.01 USDC required per call
