Phased Retirement Salary Path Calculator
Income across a phased retirement.
Project income across a phased retirement where hours and salary reduce over a set number of years. Enter annual salary to see total income across the phase.
What this tool does
Phased retirement cuts hours gradually rather than stopping abruptly, with income decreasing each year of the phase. This calculator takes your current annual salary, the percentage by which income drops each year, and the number of years in the phase, then shows total income across the entire period plus a breakdown of salary for each individual year. The result illustrates how income transitions over time as work hours reduce incrementally. Each year's salary is calculated by applying the annual reduction percentage to the previous year's amount. The primary drivers of your total income are your starting salary and the reduction percentage—larger reductions compress total earnings more sharply. This tool models a linear transition pattern and assumes the reduction percentage remains constant throughout. The output is for illustration only and does not account for inflation, tax changes, or other real-world adjustments to earnings.

60,000 reducing 20% a year over 5 years generates total phase income of about 201,696 — versus 300,000 at full salary. The 98,000 'cost' is bought time and a softer transition into full retirement, often worth it for wellbeing and pension drawdown smoothing.
A worked example
Try the defaults: current annual salary of 60,000, annual reduction of 20%, phase years of 5. The tool returns 201,696.00. You can adjust any input and the result updates as you type — no submit button, no reload. That's the real power here: seeing how sensitive the output is to one or two assumptions.
What moves the number most
The result responds to Current Annual Salary, Annual Reduction, and Phase Years. The rate and the time horizon usually dominate — compounding means a small change in either reshapes the final figure more than a similar shift in contribution size. Test this by doubling one input at a time.
The formula behind this
Each year's salary equals the prior year times one minus the reduction percentage. Total is the sum across phase years. Final-year salary is the starting salary times (1 − reduction)^years. Everything the calculator does is shown in the formula box below, so you can check the math against your own spreadsheet if you want.
What the headline number hides
Gross pay, net pay, and what actually lands in your account can differ by thousands depending on tax code, benefits, pension contributions, and student loan deductions. This tool isolates one piece of that picture — always pair it with a take-home calculator for the full view.
What this doesn't capture
Tax bands, pension contributions, student-loan deductions, and benefits-in-kind sit outside this calculation. The figure is the headline; your actual position depends on local tax rules and personal circumstances. Pair with a dedicated take-home calculator for the full picture.
Over 5 years with 20 annual reduction from £60,000, your phased retirement income totals 201,696.00.

Sources & Methodology
Methodology
The calculator computes total income across a phased retirement by applying a consistent annual reduction to salary. Starting with your current annual salary, each subsequent year's salary is multiplied by one minus the annual reduction percentage. This compounds over the specified number of phase years, so the salary decreases by a fixed percentage each year rather than a fixed amount. The total phased income is the sum of all yearly salaries across the retirement period. The model assumes a constant reduction rate throughout the phase, treats salary changes as smooth and predictable, and does not account for inflation, bonuses, tax withholding, or changes to the reduction rate. The final-year salary will equal your starting salary multiplied by (1 − reduction percentage) raised to the power of the number of years.
