Your joint finances are running a structural deficit of nearly £1,500 monthly—that -79.4% savings rate signals the household income isn't covering shared expenses, which is the primary pressure point to address. On the positive side, your personal position remains solid: a 29.7% savings rate and £179,279 in liquid assets provide meaningful buffer, though commission volatility (£18,581 average against a £38,145 ceiling) creates some earnings uncertainty. Your investment portfolio at £131,089 comfortably exceeds your outstanding mortgage of £170,323, and total net worth of £620,044 positions you well—the issue isn't asset accumulation, Sir, it's the joint spending baseline. The real work lies in either reducing shared household costs or increasing joint income; your personal finances are financing the gap but that model isn't sustainable indefinitely. Systems nominal: cash reserves adequate, pension funded, commission tracking stable.
