Could I Retire At 55?
Most defined-contribution pots can still be accessed from 55 today. That window closes for many people on 6 April 2028, when the normal minimum pension age becomes 57. State Pension is later still — 66 now, rising to 67. The years in between are a cash-flow problem: workplace pensions, SIPP, defined benefit, ISAs and spending on one timeline. Born between 6 April 1971 and 5 April 1973, the date you stop work can decide whether 55 is even available.
A journey can hold this event and later ones. Two free journeys, 15-year cap. Paid paths run 30 years.

Then The Events That Follow
This question starts the journey. Add later events on the same years so tax, leftover cash, childcare and retirement move together. A calculator answers one slice. Free paths run 15 years; paid unlocks run 30.
How Kumberi Models An Earlier Stop
Access Age Is A Rule, Not A Preference
Defined-contribution access follows the normal minimum pension age in the product: 55 until 6 April 2028, then 57 (Finance Act 2022). Withdrawals before that age are not paid as pension income. How workplace, SIPP, defined benefit and State Pension sit together is in UK Pension System and Retirement Planning. State Pension starts at State Pension age, not at 55.
Pots, ISAs And The Tax-Free Lump Sum
You can illustrate a tax-free lump sum and a withdrawal path. Leftover cash in working life follows the surplus policy you set (by default emergency buffer, then remaining ISA allowance, then savings) — a modelling assumption, not a recommended mix. Withdrawal rates explain how Kumberi applies safe-withdrawal ideas; they do not replace UK tax on drawdown.
A Single Path Versus A Range Of Markets
The free trial is a deterministic path under return and inflation assumptions you can inspect. Monte Carlo path bands and historical market paths are on paid unlocks, not the 15-year free cap. Treat every chart as an illustration. FIRE strategy modelling is the longer write-up of early-stop what-ifs in this product.
A 4% Rule On Its Own Is Not This Decision
Withdrawal rates explain how Kumberi applies safe-withdrawal ideas. They do not replace UK tax on withdrawals, State Pension timing, or the years between 55 and State Pension age. Model the age on a journey if those years are the actual question.
Read FIRE Strategy ModellingWhat This Page Does Not Model
- Monte Carlo path bands and historical backtesting are on paid unlocks. The free tier caps projections at 15 years.
- Kumberi does not give regulated retirement advice or recommend an annuity, drawdown product or retirement date.
- Protected pension ages below the standard minimum are not a general case. Do not assume the engine has applied a protected age unless you have set that in the journey.
Common Questions
Can I Take My Pension At 55 In This Model?
Defined-contribution access follows the normal minimum pension age: 55 until 6 April 2028, then 57. The model will not pay pension income before that age. State Pension is separate and starts at State Pension age.
Does Kumberi Say Whether I Can Retire At 55?
No. It projects cash flow and pot drawdown under your inputs. A summary verdict describes the modelled path; it is not permission to stop work. See FIRE Strategy for how early-stop what-ifs are framed in the product.
Is Monte Carlo Included On The Free Trial?
No. Market-path ranges are paid-depth. The free trial is two journeys with a 15-year cap and the deterministic UK tax engine. How those simulations are built is in Monte Carlo Simulation.
