What is the Single vs Couple Retirement Spending Calculator?
The Single vs Couple Retirement Spending Calculator helps you understand how retirement finances differ when planning as a single person, as a couple, and in the event that circumstances change later in life. It shows how spending, assets and income evolve under each scenario so you can plan with greater resilience.
How the Calculator Works?
This calculator models three parallel retirement scenarios in real terms, using today’s spending power.
The single scenario reflects one person’s retirement, typically with lower housing and living costs and one State Pension.
The couple scenario models joint retirement, including higher shared costs, combined assets and two State Pensions where applicable.
The transition scenario models a realistic change from couple to single later in retirement, reflecting survivor benefits, reduced household spending and changes to income sources.
For each scenario, the calculator projects asset growth, income, withdrawals and spending year by year. It applies a tax-efficient withdrawal order and shows how long assets last under each path.
Step One: Enter Shared Assets and Income
Add your combined savings, investments, pensions and expected retirement income.
Step Two: Set Spending Assumptions
Define retirement spending for a single household and for a couple, including how costs change if circumstances shift later.
Step Three: Compare Outcomes Across Scenarios
Review side-by-side projections, year-by-year tables and asset balances to see how each scenario affects long-term sustainability.

What is the Single vs Couple Retirement Spending Calculator?
It is a UK-specific planning tool that compares single, couple and transition retirement scenarios to show how spending and assets evolve under different household circumstances.
Why compare single and couple scenarios?
Because retirement costs and income can differ significantly between one-person and two-person households, especially over longer retirements.
What does the transition scenario represent?
It models a change from couple to single later in retirement, reflecting survivor events and the associated changes in spending and income.
Does this include State Pension changes?
Yes. The calculator accounts for one or two State Pensions, depending on the scenario.
Are figures shown in today’s money?
Yes. All projections are inflation-adjusted so you can compare real spending power.
How are assets withdrawn in retirement?
Withdrawals follow a tax-efficient order, typically using cash first, then ISAs and GIAs, and pensions when accessible.
Does it assume spending halves when one person remains?
No. The calculator recognises that many costs remain fixed and allows spending to reduce more realistically rather than proportionally.
Is this about predicting life events?
No. It is about stress-testing plans against common changes so retirement strategies are more robust.
Is my data stored?
No. All calculations run locally in your browser and no data is sent to servers.
Can I export the results?
Yes. You can download CSV files for each scenario or copy a summary to the clipboard.
