Military Savings Basis and Actual Payout Limits
Reference date and last reviewed: July 11, 2026
Calculation Basis
Estimates installment-savings principal and bank interest from the monthly contribution and term, then applies the current baseline of a 550,000 KRW personal monthly limit and a 100% matching-support assumption on contributed principal.
Reference Limits
It does not determine each bank's base or preferential rate, payment dates, early termination, remaining service period, tax-exemption eligibility, or support-payment conditions, so it cannot guarantee the actual maturity payout.
When to Confirm Officially
Before opening or closing an account or finalizing a discharge-fund plan, confirm the bank's product terms and the latest Ministry of National Defense and Military Manpower Administration guidance for limits, eligibility, and support-payment conditions.
Usage Tips
Compare Korean military savings maturity amounts by contribution and term
Military installment savings for Korean service members can vary by monthly contribution, saving term, bank rate, and matching-support assumptions. Use the current monthly limit and matching-support baseline to compare principal, bank interest, matching support, and estimated maturity amount in one view.
What is Military Savings Calculator?
The Military Savings Calculator estimates maturity amount for Korean military installment savings such as soldier savings plans. Enter monthly contribution, saving term, and annual bank rate to review contributed principal, bank interest, matching support, total benefits, and benefit percentage against principal using the current baseline monthly limit, matching support, and tax assumption. It is useful for planning discharge funds and comparing how different monthly contribution levels affect the final amount.
How to Use
- 1Enter the monthly contribution you plan to deposit.
- 2Enter the monthly contribution. The current baseline monthly limit is 550,000 KRW, so larger values are not accepted.
- 3Choose the saving term. Quick buttons are available for common 18, 20, and 21 month service-related terms.
- 4Enter the annual bank rate. Adjust it based on whether you meet preferential-rate conditions.
- 5Review the fixed calculation baseline shown on the page: monthly limit, matching support, and interest tax.
- 6Review estimated maturity amount, principal, bank interest, benefits, and matching support.
- 7Copy the result into discharge-fund plans or monthly savings notes.
Separating principal, bank interest, and matching support
Last reviewed: July 11, 2026Installment-interest and maturity formula
Bank interest = monthly deposit × (annual rate ÷ 12) × n(n+1) ÷ 2
The simplified installment model assumes each monthly deposit earns interest for a different remaining term. Maturity amount is principal plus net bank interest plus matching support calculated from principal.
Depositing KRW 550,000 for 18 months
- • KRW 550,000 monthly deposit and 18-month term
- • 5% annual bank rate and 100% matching rate
- • 0% interest tax and KRW 550,000 monthly limit
- 1. Principal = 550,000 × 18 = KRW 9,900,000
- 2. Bank interest = 550,000 × (0.05 ÷ 12) × 18×19÷2 = KRW 391,875
- 3. Matching support = 9,900,000 × 100% = KRW 9,900,000
Estimated maturity amount is about KRW 20,191,875, with total benefits about 103.96% of principal.
How to read the result
- Principal and matching support drive more of this example's maturity amount than bank interest, so deposit size and term matter greatly.
- Amounts above the monthly limit are not applied, so entering a larger number does not increase the estimated principal or support.
Conditions that change the result
- The calculator does not determine bank preferential rates, payment dates, early termination, tax exemption, or support eligibility.
- The tool currently caps monthly contribution at KRW 550,000 and accepts matching and tax assumptions, but current official guidance takes priority when rules change.
Common input mistakes
- Enter an annual rate of 5 for 5%, not 0.05; the form uses percentage values.
- Do not apply the matching rate to bank interest. The tool applies it to contributed principal.
Reference Knowledge
- ●The calculator uses a simplified installment-savings model where each monthly contribution earns interest for its remaining term.
- ●Estimated gross bank interest = monthly contribution × monthly rate × months × (months + 1) ÷ 2.
- ●Interest tax is calculated by multiplying gross bank interest by the entered tax rate.
- ●Matching support is estimated by multiplying applied contributed principal by the current baseline matching support rate of 100%.
- ●Actual contribution limits, bank rates, preferential rates, matching support rates, and eligibility rules can change by period and product notice. This tool currently caps the monthly contribution input at 550,000 KRW.
- ●Early termination, delayed contributions, signup date, maturity date, service status, tax exemption, and support-claim conditions can change the actual payout.
- ●For final payout decisions, confirm the bank product terms and official guidance.
FAQ
Q.Is the estimate the same as the actual maturity payout?
No. This is a reference estimate from your inputs. Bank-specific preferential rates, payment dates, early termination, tax exemption, and matching-support eligibility can change the actual payout.
Q.Can I enter more than 550,000 KRW per month?
No. For the current Soldier Tomorrow Savings baseline, the monthly contribution is capped at 550,000 KRW. The monthly limit is not a user input; it is shown as a fixed calculation baseline.
Q.How is matching support calculated?
This tool multiplies applied contributed principal by the current baseline matching support rate of 100%. Actual eligibility and payment conditions should be checked in official guidance.
Q.Why is the interest tax rate shown as 0?
Military savings may be tax-exempt when conditions are met. This tool fixes the interest tax rate at 0% for a simple reference estimate.
Q.Which bank rate should I enter?
Use the annual rate you expect to actually receive from the bank, including preferential rates only when you can meet their conditions.
