Why two users can see different results
Why the result can differ
Different tax codes, payroll periods, Scottish bands, pension methods or lender assumptions can change the outcome.
One-off bonuses, pay frequency, overpayments, allowances and reliefs can move the result away from a simple annual estimate.
Where a rule depends on eligibility or legal status, this page shows an estimate and links to official guidance.
This section is intentionally repeated on key tools so the explanation stays near the result instead of being hidden in a separate policy page.
COMMON QUESTIONS
Frequently asked questions
Is 25% always tax-free?
Not always. Tax-free cash depends on current allowances and any protections.
Should I take the lump sum immediately?
That depends on your retirement plan, tax position and income needs.
Does taking cash reduce future income?
Usually yes, because money removed from the pot is no longer available to fund retirement income.
