結果の見方
The two lines are the net worth of the buy path and the rent path by year. Where they cross, the leader changes; if they never cross, the same side leads throughout.
The result depends entirely on your assumptions, above all the yearly change in home prices and the renter’s investment return. Change those two and watch the chart to see how sensitive the conclusion is.
この結果が出るしくみ
Buyer net worth = home value less selling costs and loan balance. Renter net worth = the down payment plus one-off buying costs, plus the monthly difference saved, compounded at the return you enter. Whichever side spends more each month sets the shared budget, and the other side saves the difference. Mortgage interest deductions, tax differences and moving costs while renting are not included.
買方淨資產 = 房屋現值扣賣出成本與貸款餘額。租方淨資產 = 頭期款加買方一次性成本,再加每月省下的差額,以你填的年報酬率複利累積。兩邊每月現金流出取較大者當共同預算,花得少的一方把差額存起來。不含房貸利息扣除、稅負差異與租屋期間的搬遷成本。結果完全取決於你填的假設。

よくある質問
How does this tool compare buying and renting?
Buyer net worth is the home value less selling costs and the loan balance. Renter net worth is the down payment plus one-off buying costs, plus the monthly difference saved, compounded at the return you enter. The default case is a NT$15M home with NT$4.5M down, a 30-year loan at 2.318% and NT$30,000 monthly rent, compared over 30 years.
Why is the default home-price growth 0?
The defaults are 0% yearly price change, 0% yearly rent growth and 0% return for the renter, so the tool does not start from an optimistic or pessimistic future. To test rising or falling prices, change these three; the result moves noticeably.
What costs does the buyer pay?
By default the buyer pays one-off costs of 2% of the price (agent and paperwork fees, deed tax), yearly holding costs of 1% (property and land tax, management fees, repairs) and selling costs of 4% of the sale price. These are illustrative assumptions; change them to fit your case.
Can I treat the result as advice on whether to buy?
No. The result depends entirely on your assumptions, leaves out mortgage interest deductions, tax differences and moving costs while renting, and does not forecast prices. In the default case, at the end of year 30 the buyer’s net worth is NT$14.4M and the renter’s is NT$13.1M; this only shows how the calculation works.
