How to use this tool
Enter gross salary, eligible credit and debit/cash-receipt spending, and child count. The model fills the 25% salary threshold with credit spending first, so separate ineligible purchases before entry.
Results and examples
Remaining credit spending uses 15% and debit/cash uses 30%, subject to embedded caps. The golden-ratio comparison reallocates the same total spending without evaluating card rewards or purchase necessity.
Worked example
KRW 40 million salary, 10 million credit and 5 million debit leaves a KRW 1.5 million debit-based deduction after the threshold.
Limitations
- Additional market, transport and culture categories and excluded-purchase checks are absent.
- Child-related limits and tax-year eligibility must be checked against filing information.

Frequently asked questions
Does a 1.5 million deduction mean that refund?
No. An income deduction differs from a tax refund.
Should I spend more to increase it?
The deduction alone cannot justify extra consumption.
