Is compound interest calculated daily, weekly, monthly or yearly? Does it just depend on the provider?
A 25 year term with those rates and monthly payments, you'll be paid off by month 71.
A great compound interest calculator I found. Not mine, from Vertex42. Should work and its shared read-only.
@Classic Blue Theme I used your example but change as needed.

My offer has been accepted by Santander, it just needs finalising today and submitting.
£100,000 borrow, 10 year term, 5 year fixed at 5.79%
£1099 PCM / no fee / free legals
Santander will allow the product to be switched (if interest rates do drop a bit) anytime after offer
I've calculated I can have this paid off in 5 years if I overpay by £825 a month. (£1924 total)
If I had the same rate I did 5 years ago, id be 10k better off...
BUT... If I applied for the same mortgage I did 5 years ago (2.21%, 25 year yer, £834/month) but with the interest rates today after 5 years it would have gone from 192,000 balance to 198,000 balance!

At 2.1% it would have been 161,500 balance! For it to be around the same balance after 5 years, the monthly payments would have gone from £834/month to £1400/month. That was impossible at the time
Thankfully I overpaid my balls off, paid my 'gifted' loan back and borrowed more money to bring it down to 100k.
Yes, I could look at high interest rate savings account instead but Id rather just have my mortgage paid off so I can either pay £0 / month (sounds incredible!) rent this place out and move somewhere else or sell up (which would be stupid based on the location and rental potential)
