Telecom cost calculator guide

This English page translates the Korean telecom cost calculator and calls calculateTelecomCost, getAllPlans, getPlanById, calculateBundleDiscountRate, calculateFamilyDiscountRate, calculateLongTermDiscountRate, calculateWelfareDiscount, compareCarriers, calculateYearlySavings, and recommendOptimalPlan. It preserves 2026 January mobile plan data, 5G, LTE, MVNO, internet, IPTV, phone plus internet plus IPTV bundle 20%, family four-line 25%, long-term 10-year 20%, welfare discounts, and yearly savings.

Mobile, internet, and IPTV base cost

The source starts with the selected mobile plan price, then adds internet and IPTV prices if the user includes those services. The plan dataset covers SKT, KT, LG U+, and MVNO, with 5G unlimited, 5G limited, and LTE plans.

Additional services are present in the constants, but the current calculation keeps additional service price at zero. That behavior is preserved so English and Korean outputs stay aligned.

Bundle, family, long-term, and welfare discounts

Bundle discounts apply to the mobile plan. Phone plus internet is 10%, phone plus IPTV is 8%, internet plus IPTV is 5%, and phone plus internet plus IPTV is 20%. Family discount is 15% for two lines, 20% for three, and 25% for four or more.

Long-term discount is 5% from two years, 10% from three years, 15% from five years, and 20% from ten years. Welfare reductions include registered disabled, veteran, basic livelihood recipient with up to KRW 26,000, and near-poverty with up to KRW 11,000.

Reading the comparison

The result reports monthly total, yearly total, total discount, and savings rate versus the same services before discount. Carrier comparison and optimal-plan recommendation reuse the same plan list.

Real telecom bills can include promotions, device installments, roaming, paid content, one-time installation fees, and contract penalties. Those should be checked separately before switching.
