Rent-deposit calculator

See exactly how a deposit change maps to monthly rent under an annual conversion rate. The legal ceiling and a negotiated market rate are different concepts.

Legal reference ceiling · 03 Sep 20265.00% / per year

The lower of 10% or the Bank of Korea base rate 3.00% + 2 percentage points. This is a ceiling for covered deposit-to-rent conversions, not a promised negotiation rate.

Use the 5.00% reference ceiling shown above, or enter the rate offered in your negotiation.
Deposit difference₩0more deposit
Reference monthly rent change₩0rent reduction
Reference new monthly rent₩0

Formula Deposit difference × annual rate ÷ 12 = monthly rent change. Example: ₩10,000,000 × 5% ÷ 12 ≈ ₩41,667/month.

The statutory ceiling does not force a landlord to accept the reverse conversion from rent to deposit. Contract type, renewal timing and legal coverage matter.

Dates

Compare age and calendar conventions

Choose whether the recorded birthday is solar (양력) or Korean lunar (음력). The calculator converts it before applying an age rule.

International age—
Traditional counting age—

International age · 만 나이Starts at 0 and increases on the birthday. Official use is generally based on the converted solar date.

Traditional counting age · 세는나이Starts at 1 and increases on 1 January. It remains in some social contexts but is not the default legal rule.

Solar · 양력 / Korean lunar · 음력Solar vs lunar birthday changes the anniversary date, not the age formula. A lunar date must first be converted; 윤달 cannot be guessed.

Offline Korean lunar conversion · supported range 1000–2050. 돌, 연 나이 and institution-specific cutoffs are separate.

Electricity in Korea

Check your plug and voltage before you pack

Choose where your device comes from. Korea uses 220 V, 60 Hz and two round-pin sockets (types C and F).

Read the label on the device or charger

“INPUT 100–240V, 50/60Hz” means it can accept Korean power; you may only need a plug adapter. A device marked only 100, 110 or 120V needs a correctly rated step-down transformer. For hair tools and heaters, buying a 220V model is often safer than using a travel transformer.

What you may need

Universal travel adapter

For phones and multi-voltage chargers from countries with a different plug.

Grounded Korea plug adapter

For compatible grounded equipment; match the earth connection and device plug.

220→110V step-down transformer

Only for 100–120V equipment; must exceed the device wattage.

Waste & recycling

🗑️ Find the right trash bags for your address.

Korea’s official pay-as-you-throw bags are local. Search near your home, buy the correct bag, and check your district’s sorting and set-out rules.

Buy the local bag

Search for an authorized seller near your address. Supermarkets and convenience stores often carry them, but stock and available sizes vary by branch.

Separate by waste type

General waste uses a local standard bag. Food waste may use a separate bag, tag, chip or RFID machine. Recyclables follow a separate local collection system.

Moved to a new district?

Bags from your former city or district may not be accepted. Ask the new district office about an exchange or authorization sticker before using leftovers.
