What is the Hybrid Pension (DB + DC) Retirement Calculator?
The Hybrid Pension (DB + DC) Retirement Calculator helps you plan retirement when your income comes from a mix of guaranteed Defined Benefit pensions and flexible Defined Contribution savings. It shows how these sources work together alongside ISAs, other investments and the State Pension to fund retirement sustainably.
How the Calculator Works?
This calculator models your retirement finances year by year in real terms, meaning all figures are adjusted for inflation to reflect today’s spending power.
It separates guaranteed income from flexible income. Defined Benefit pensions provide a stable, inflation-linked income base, while Defined Contribution pensions, ISAs and other investments are drawn down as needed to meet spending. The model applies UK tax rules and shows net income after tax rather than headline figures.
If you retire before DC pensions are accessible, the calculator automatically models a bridge period using ISAs and other accessible assets. Once pensions and the State Pension begin, it shows how reliance on drawdown reduces over time.
You can test different retirement ages, spending levels and drawdown strategies to see how robust your plan is.
Step One: Enter Your Pensions and Assets
Add your Defined Benefit pension details, Defined Contribution pots, ISAs and other investments, along with expected access ages.
Step Two: Set Retirement Timing and Spending
Choose your retirement age, spending level and drawdown approach, including how tax-free cash is taken.
Step Three: Review Income Mix and Sustainability
See how guaranteed income and drawdown interact over time, review net income, pot balances and bridge period coverage.

What is the Hybrid Pension (DB + DC) Retirement Calculator
It is a UK-specific tool that models retirement using both guaranteed DB income and flexible DC drawdown, showing how they combine to fund retirement sustainably.
What is a hybrid DB and DC retirement plan?
It is a plan that combines defined benefit income, which is normally promised by a scheme, with defined contribution pots whose value and withdrawals can change. The DB pension may cover part of your core spending, while the DC pot, ISA and cash provide flexibility. The calculator shows how those parts meet across different ages rather than treating them as one pot.
Why should I enter each pension separately?
Because start dates, inflation rules, tax and survivor benefits can differ. A final salary pension at 60, a career average pension at 67 and a SIPP at 57 each do a different job. Combining them into one total can hide the years when income is missing and make early retirement look safer than it is.
How are early retirement reductions handled?
Enter the actual reduced pension offered at your chosen date where possible. Defined benefit pensions are often permanently reduced when taken before Normal Pension Age because they are expected to be paid for longer. The reduction factor varies by scheme and timing, so the official scheme quote should override a generic estimate.
Should I take the DB pension early or use the DC pot as a bridge?
Compare both routes. Taking DB early gives secure income sooner but usually locks in a lower annual amount. Using DC or ISA money first may preserve the full DB pension, but increases early withdrawals and market exposure. Look at lifetime income, tax, survivor benefits and how much flexibility remains, not just the first year’s income.
How does tax work when several pensions start?
Defined benefit pensions, State Pension and taxable DC withdrawals normally stack together for Income Tax. ISA withdrawals are normally tax-free. A year that looks efficient before State Pension starts can become more taxable afterwards. Model withdrawals by person and by tax year so you can use allowances sensibly without making tax the only goal.
Can I take tax-free cash from the DC pension?
Usually, subject to your remaining lump sum allowance and scheme rules. Taking cash can fund the bridge or create a reserve, but it also reduces the invested pot available for later. Taking tax-free cash alone will not normally trigger the Money Purchase Annual Allowance, while taking taxable flexible income often will.
What survivor benefits should a couple include?
Check the scheme booklet or statement for the pension payable after your death. It may be half, another percentage or subject to other scheme rules. Then rerun the household with one State Pension, the survivor pension and spending that is lower but not halved. A plan can look strong for a couple but leave the surviving person short of income.
Do DB pensions always keep pace with inflation?
Not always in full. Increases before and after retirement depend on the scheme rules, service dates and any caps. Enter the scheme’s own increase basis where the calculator allows, or use a cautious assumption after inflation. Do not assume every defined benefit pension fully keeps pace with inflation.
Can I transfer the DB pension into the DC pot?
Some private-sector schemes may offer a transfer value, but most unfunded public service schemes do not allow transfers to flexible arrangements. Giving up safeguarded benefits is a major and often irreversible decision, and regulated advice can be compulsory above the statutory threshold. This calculator is for planning income, not endorsing a transfer.
What is the best way to use the result?
Look for the gaps between income start dates and give each part of the money a clear job. Cash might cover bills in the next year or two. An ISA might fund the early bridge. Defined benefit income could cover the basics, with the defined contribution pot paying for flexible spending. A good plan should make those jobs easy to understand.
Are returns shown in today’s money?
Yes. All projections are inflation-adjusted to show real spending power.
Can I compare different scenarios?
Yes. You can run side-by-side scenarios to compare retirement ages, spending levels and assumptions.
Is my data stored?
No. All calculations run locally in your browser and no personal data is saved.
Can I export the results?
Yes. A CSV export is available with full year-by-year projections.

Behind Retirement Calculators
Built from the questions I was asking myself
I'm Ryan, the person behind Retirement Calculators. I started the site after selling an online business and trying to understand what our pensions, ISAs, investments and property actually meant for the way we wanted to live.
The calculators are built around those real decisions: whether you could work less, retire earlier, spend more now or use your money differently. They will not give you a perfect answer, but they can make the trade-offs much easier to see.
