Declining balance depreciation calculator
Build an accelerated depreciation schedule with an explicit switch to straight line.
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, whole-number life, factor and switching. Factor divided by life is the annual rate, at most 100 percent. Use switching straight-line to switch when remaining straight-line depreciation equals or exceeds declining depreciation, or never to keep declining balance. The final year always adjusts to residual and is labeled explicitly. No tax rules or partial-year convention are applied. 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.

Use the right inputs
Provide one JSON asset with cost, residual, whole-number life, factor and switching. Factor divided by life is the annual rate, at most 100 percent. Use switching straight-line to switch when remaining straight-line depreciation equals or exceeds declining depreciation, or never to keep declining balance. The final year always adjusts to residual and is labeled explicitly. No tax rules or partial-year convention are applied.
