Total buying cost after deducting net sale proceeds
1,750,522.45TWD
Under your assumptions, buying costs TWD 250,522.45 more than renting. This assumes you sell the property and repay the remaining mortgage at the end. Potential returns from saving or investing the down payment are excluded.
Rent over the same period1,500,000 TWD
Buying net cost minus rent (positive means buying costs more)250,522.45 TWD
Monthly mortgage principal and interest (other fees excluded)29,569.56 TWD
Mortgage payments during the period1,774,173.47 TWD
Of which: interest750,522.45 TWD
Principal outstanding at the end6,976,348.98 TWD
Proceeds after selling, fees and loan repayment2,623,651.02 TWD
Use the same currency throughout. Mortgage payments are fixed-rate equal principal-and-interest payments at month-end; monthly interest = annual rate ÷ 12. Buying net cost = down payment + purchase fees + payments during the period + ownership costs − (assumed sale price − sale fees − outstanding principal). Rent cost = monthly rent × months. Down payment and principal build equity, so total mortgage payments alone should not be compared with rent. Include taxes, insurance and repairs in your entered costs. Opportunity costs, rent increases, investment returns, tax relief and returned deposits are excluded; grace periods and variable rates are not modeled. The sale price is your assumption, not a forecast. A negative net cost is a nominal result under those assumptions, not a guaranteed profit.
Method and scope
Buying net cost is down payment plus buying fees, mortgage payments and ownership expenses, minus resale proceeds after selling fees and remaining principal. Renting cost is monthly rent times months; the mortgage uses fixed-rate end-of-month equal payments with annual rate divided by 12.
Principal payments and the down payment build equity, so total mortgage payments alone are not comparable with rent. A negative net buying cost reflects the entered sale assumption and does not guarantee a profit.
Include tax, insurance and repairs in the appropriate costs without counting them twice. Opportunity cost, investment returns, rent increases, tax concessions, refundable deposits, grace periods and variable rates are excluded; all money uses one currency.

What this helps you do
Compare nominal renting cost with buying and selling a home over the same period. State your own resale assumption rather than treating it as a prediction.
What to enter
Start with property price (10,000 twd), then fill the other relevant fields in the units shown. The field hints explain the required format and examples.
How the calculation works
Buying net cost is down payment plus buying fees, mortgage payments and ownership expenses, minus resale proceeds after selling fees and remaining principal. Renting cost is monthly rent times months; the mortgage uses fixed-rate end-of-month equal payments with annual rate divided by 12.
Worked example
For a TWD 8,000,000 property, enter 800 in a field marked 10,000 TWD. Enter 30 for a 30-year loan and 5 for a five-year comparison; a previously saved uneven-month term can instead be displayed in months.
Understanding the answer
Principal payments and the down payment build equity, so total mortgage payments alone are not comparable with rent. A negative net buying cost reflects the entered sale assumption and does not guarantee a profit.
Scope and limitations
Include tax, insurance and repairs in the appropriate costs without counting them twice. Opportunity cost, investment returns, rent increases, tax concessions, refundable deposits, grace periods and variable rates are excluded; all money uses one currency.
