About the Founder

Simon Bondham
Founder & Chief Strategist, PlanMyDebt.com
For the past 40 years, I have worked across the globe in over 20 countries—including the USA, Canada, China, Brazil, Mexico, France, and Sweden—flying into struggling businesses to fix their strategic planning, overhaul their financial processes, and save them from the brink of collapse.
Operating from my base in the UK, I have been responsible for managing and restructuring budgets of up to £700 million. When a business of that scale is drowning in debt, the solution is rarely a magic trick. It is always about facing the numbers, building a ruthless, mathematically sound plan, and executing it without emotion.
I built PlanMyDebt.com because the exact same principles apply to personal debt.
Over my career, I have personally had debts, cleared debts, had them again, and cleared them again. I know exactly what it feels like to be overwhelmed by the numbers, and I know that the only way out is a structured, strategic plan. The methods used in this calculator—specifically the Avalanche and Snowball strategies—are not theories. They are the exact mathematical frameworks I have used to turn around multi-million-pound companies and manage my own finances.
I am not a regulated financial adviser, and PlanMyDebt.com does not offer financial advice. What I am is a strategist who understands that debt is a math problem, and math problems have solutions.
I built this tool to give you the clarity and the strategy you need to solve yours.
My Philosophy on Debt
1. Face the numbers
You cannot fix what you refuse to measure. The first step to clearing debt is knowing exactly what you owe, down to the penny.
2. Strategy beats willpower
Motivation fades; a mathematical plan does not. Relying on willpower to get out of debt is exhausting. Relying on a structured system is sustainable.
3. Action over anxiety
The moment you have a clear payoff date, the anxiety begins to disappear. A plan replaces fear with control.
