Units of production depreciation calculator
Allocate depreciation by actual production and identify output beyond expected lifetime units.
Choose Single scenario to enter values in the fields. Choose Multiple records (JSON) to paste an advanced asset or record list. Guided numeric fields accept local decimal digits and separators without grouping; advanced JSON keeps strict ASCII syntax. Provide one JSON asset with cost, residual, expectedUnits and a chronological production array containing date and units, plus optional label. Depreciation follows rounded cumulative cost allocation by actual output. Excess output beyond expected lifetime units is reported separately, never reducing book value below residual. Same-day entries remain separate. No production forecast or useful-life change is inferred. Use JSON up to 1000000 characters, 50000 values and 64 nesting levels. Period, invoice and production lists allow up to 2000 records; annual schedules allow 1 to 1000 years. Amounts use plain ASCII decimals up to 1000000000000 and zero to six selected decimal places. Quoted decimal strings preserve exact input. JSON and CSV preserve the full report and source, with exports bounded to 40 million characters and 500000 CSV records. Analysis runs locally with a 10-second timeout. No data is uploaded. Preview tables show the first 200 rows; copy returns the summary. Up to 1,000,000 characters. Review the settings before running.
