何を計算するか、いつ使うか

Compare your current mortgage with a new one〜see the monthly saving、the break-even point on switching fees、the 合計 原価 over the loans.

使い方の手順

1. Enter your 電流 残高、利率、年数 left.
2. Enter the new 利率とterm,とthe fees〜switch.
3. Tick the 箱 if the fees will be added〜the new loan.
4. Check the break-even 時刻 against how long you expect〜継続 the loan.

各入力項目の意味

• 電流 残高と利率 – What you oweとyour 電流 毎年 利率.
• New 利率と期間 – The offered 毎年 利率と年.の長さ
• Fees〜switch – Arrangement、valuation, legal、exit fees.
• Add fees〜loan – paying them up front. ロール the fees into the new 残高 instead

結果の読み方

• 毎月 変動 – 電流 payment minus the new payment.
• 損益分岐点 – Fees ÷ 毎月 節約額.
• 合計有給 – All payments over 1個あたり loan, plus fees if 有給 up front.

計算式

Payment = P × r ÷ (1 − (1 + r)^−n)個で1個あたり loan. Break-even か月 = switching fees ÷ 毎月 節約額. 合計 原価 compares payment × か月 on 1個あたり loan.

計算例

A 250,000 balance at 6.75% with 27 years left costs 1,679.00 a month. A new 5.75% loan個でfees costs 1,521.17 27 years with 3,000、1 year 8 months,の157.83 a month. The fees are repaid a saving、the total saving over the loansはabout 48,137.です

前提と限界

• Both rates are fixed.
• A longer new 期間 lowers the payment but 缶 raise the 合計 原価; the 結果 flags this.
• 税額、cash-out、changes〜insurance are not modelled.

よくある間違い

• Ignoring early repayment charges on the old loan.
• Resetting〜a 30-year termとignoring the extra 利息.
