Re-mortgage calculator (locking in for longer)

Options
Morning Hive Mind,

Before I start down the route of a excel spreadsheet and no-doubt reinvent the wheel, does anyone know of a re-mortgage calculator for the following scenario;

  • Quit 5 year fix with 3 years remaining and paying exit fee
  • Re-mortgage onto a 10 year deal, fractionally higher interest rate
  • Exam question - what would the average rate have to be for years 4-10 be to break even on paying the exit fee on the existing deal and the marginally higher rate for years 1-3?
Thanks in advance.

    That would be great, thanks.  Details as follows:

    Principle - £165k
    Payments - £708 at present, £720 if we move.
    Currently 1.49%, moving to 1.66%
    Cost to move £3,500 ERC and £999 fee on the new deal
    Current deal has 36 months to run.  New deal would be for 120 months.

    Thanks.

    So if 2.2% is the breakeven then I ask myself, "will I be able to re-mortgage @ 2.2%  or lower in 3 years time"?  Hmmmmm

    If you have a spare £4,500 plus other costs to move lenders then overpay every month instead.

    But then we get into the overpay or invest debate that must have been done to death I'd imagine.

    That the dilemma everyone has,  does the ERC drop at any point....

    Nationwide put their 5y fee fix up to 1.74% on 24 Feb  some lenders are already over 2%
    (nationwide low was 0.84% last Sept)

    Here is the table for the difference in 10y based on a few rates in 3years time.
    £147,046 1.50% £99,587 £6,581.18
    £147,046 2.00% £104,263 £1,905.59
    £147,046 2.20% £106,182 -£14.04
    £147,046 2.50% £109,116 -£2,947.68

    I used the add the fees model if we use the overpayment of the fees it looks like this.
    Mortgage £160,501
    payment £720 ERC/FEE
    rate 1.49% £3,500
    new rate 1.66% £999
    Time Years months
    Left on current

    New fix term 0 120

    £160,501 1.49% £141,342
    £165,000 1.66% £146,862

    £160,501 1.49% £93,165
    £165,000 1.66% £100,858



    Switch when ERC £0
    Break even rate needed no fee and fee) 84
    £141,342 2.343% £100,858
    £142,341 2.217% £100,858

    £142,341 1.50% £94,362 £6,495.43
    £142,341 2.00% £98,852 £2,005.68
    £142,341 2.20% £100,695 £162.20
    £142,341 2.50% £103,513 -£2,655.22
     
    Makes a small difference.to the main calculation.

    Noticeable after recent events how much quieter it is on this front. A new experience for a generation who've never known anything different.

    Stock market if pretty grim right now but time will offset the volatility.

    The deal I was looking at has been pulled this morning so the whole thing has just become academic.  Another boat missed.
