Have you planned how you will draw down your money in retirement?
The Retirement Drawdown Planner helps you model how your cash, pensions, ISAs and investments can support you throughout retirement. It shows how long your money can last based on your spending, income sources, real returns and the order you draw from each pot. This gives you a clear, detailed projection of whether your chosen retirement lifestyle is sustainable and where adjustments might help improve long-term security.
How the Calculator Works?
This tool runs a year-by-year projection of your retirement finances. It begins with your starting balances across cash, ISAs, GIAs and SIPPs, then applies your spending, growth assumptions, inflation mode and income sources. Cash is drawn down first, followed by invested pots, while DB and State Pension income are slotted in at their chosen start ages. The result is a complete picture of how your finances evolve from today through your planning horizon.
Step One: Enter Your Retirement Profile
Set your current age, planning horizon and opening balances across cash, pensions and investment pots. This establishes your starting point for the drawdown projection.
Step Two: Add Your Returns, Spending and Income
Choose your real return assumptions, enter your annual spending, and add any income sources such as rental income, DB pensions or the State Pension. This defines your retirement lifestyle and financial inputs.
Step Three: Review and Refine Your Drawdown Plan
View the year-by-year sustainability of your plan and adjust spending, returns, contributions or income to see how they affect how long your money lasts.

What is the Retirement Drawdown Planner?
The Retirement Drawdown Planner helps you understand how long your pension, ISA, GIA and cash savings can support your lifestyle once you start withdrawing from them via clever models and scenarios.
What does the Retirement Drawdown Planner do?
It models how your portfolio of cash, pensions and investments changes over time as you withdraw money to fund your retirement lifestyle. It includes spending, growth, inflation, and all income sources to show whether your plan is sustainable.
How does the drawdown order work?
The model always draws from cash first. When cash runs out, withdrawals move to your invested pots (ISA, GIA, SIPP) in the order you provide. You can customise pot types and balances to reflect your real-world structure.
What information do I need to use the tool?
You’ll need your current age, planning horizon, starting cash, ISA/GIA/SIPP balances, real return assumptions, annual spending target and any income sources such as DB pensions, rental income or the State Pension.
Does the calculator work in real or nominal terms?
Yes. You can switch between real (today’s pounds) and nominal (future pounds) by changing the mode. Real-mode modelling makes long-term spending easier to interpret.
Can I model one-off spending events?
Yes. You can add large purchases, holidays, home improvements or multi-year expenses. These feed directly into the yearly cash flow.
Does this tool include tax treatment?
ISA, GIA and SIPP withdrawals follow their typical UK structure in the projection, but this is a simplified model. For detailed tax planning, professional advice is recommended.
Can I add DB pensions and the State Pension?
Yes. Both can be added with custom start ages, annual amounts and real growth adjustments. The State Pension defaults to the full 2025/26 rate but can be edited.
Is my data secure when using the calculator?
Yes, none of the data is saved and is populated via math modelling only.
