Galaxy S26 Instalment Calculator (monthly payment & fee, Korea)

How it works

Amount on instalment A = price − device discount − down payment. With equal monthly payments the payment is A × i ÷ (1 − (1 + i)⁻ⁿ), where i = annual fee rate ÷ 12 and n = months; the total fee is payment × n − A. With equal principal you repay A ÷ n each month plus i × the balance still owed, so payments fall each month and the total fee is A × i × (n + 1) ÷ 2. The phone plan (data/voice) fee is not included.

FAQ

Why is the fee different from what my carrier shows?

Carriers round each monthly payment to the won and may charge the fee on the balance at the start of each month. Pick the method that matches your carrier’s terms; the difference is usually small.

Is the Galaxy S26 price in the list the current one?

The list shows the prices Samsung set from 1 October 2026. Store prices, colours and promotions change, so choose “My own price” and enter the price you are quoted.

Checked 11 Nov 2026. Preset prices: Korean prices of the Galaxy S26 series from 1 Oct 2026 as stated by Samsung Electronics and reported by SBS Biz (“삼성전자, 갤럭시S26 시리즈 가격 인상”, 1 Oct 2026); Samsung’s own store page (samsung.com/sec) could not be read by our checker, so confirm the price there before you buy. Instalment formulas: standard annuity (equal payment) and equal-principal amortisation.
