How Much Does Overpaying £200/Month Save?

On a £250,000 mortgage at 4.5% over 25 years, overpaying by £200 per month:

• Saves approximately £39,000 in total interest
• Reduces your mortgage term by around 5 years
• Total monthly payment becomes £1,590 (£1,390 base + £200 overpayment)

Compared to £100/month overpayments, the extra £100 delivers an additional £17,000 in savings — that's the compound effect of reducing your principal faster.

On a larger £350,000 mortgage, £200/month overpayments could save over £50,000 in interest and take 6 years off the term.

Before committing to regular overpayments, ensure you have an emergency fund and check your lender's overpayment limits.
