How to use Home-Improvement Credit Cap and understand its results
- Choose the specific arithmetic or checklist scenario and establish its input amounts, dates, rates and criteria from the applicable records. Keep currencies, periods and jurisdictions consistent; review the tool-specific assumptions before interpreting the result.
- Enter eligibleCosts, categoryCaps, annualCap using the field table and calculation rules, then run the tool.

- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| eligibleCosts | Eligible category costs (currency) | list of number | Required |
| categoryCaps | Category caps (currency) | list of number | Required |
| annualCap | Annual aggregate cap (currency) | number; minimum: 0 | Required |
Enter aligned nonempty nonnegative costs/caps and a nonnegative annual cap. Return category amounts before the annual cap and final capped total.
category_i=min(eligibleCosts_i,categoryCaps_i); total=min(Σcategory_i,annualCap) Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.
| Output field | Meaning | Value type |
|---|---|---|
| categoryCredits | Credits after category caps (currency) | list of number |

}Limitations and assumptions
No percentage is applied to costs and the annual cap is not reallocated among categories. Eligibility, rate schedules and statutory category definitions are not determined.
Numeric inputs must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Lists are limited to 100,000 entries; the rules above may require smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
