tax-advantaged vs Traditional Pension Breakeven Calculator
When tax-now equals tax-later.
Compare a tax-now (tax-advantaged) versus tax-later (traditional) pension contribution at different working and retirement tax rates.
What this tool does
tax-advantaged contributions use after-tax money but withdraw tax-free. Traditional uses pre-tax money but withdrawals are taxed. Enter contribution, working-life rate, retirement rate, and years to compare net retirement values.

1,000 contributed today: tax-advantaged costs 600 net at 40% working rate, grows tax-free to 4,322 at 5% over 30 years. Traditional contributes 1,000 gross, grows to 4,322 — taxed at 25% retirement rate leaves 3,242. Working rate higher than retirement rate favours traditional; lower favours tax-advantaged.
What the result means
Net retirement values for both routes shown. The bigger figure indicates the better choice at these rate assumptions. Run the math at different retirement rate assumptions to see sensitivity.
A worked example
Try the defaults: contribution amount of 1,000, working-life marginal rate of 40%, retirement marginal rate of 25%, expected annual return of 5%. The tool returns 3,241.46. 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 Contribution Amount, Working-Life Marginal Rate, Retirement Marginal Rate, Expected Annual Return, and Years to Retirement. Two inputs usually tip the answer one way or the other. Identify which ones matter most by flipping each value past a round threshold and watching whether the winning option changes.
The formula behind this
tax-advantaged: contribution net of tax now, then tax-free growth and withdrawal. Traditional: contribution at gross, growth, then taxed at retirement rate. Whichever rate is higher determines the better route. Everything the calculator does is shown in the formula box below, so you can check the math against your own spreadsheet if you want.
Using this in pay negotiations
Knowing the exact figure behind a headline rate gives you specific numbers to anchor to in conversations about pay. "The difference is £X per month after tax" lands harder than "a couple of grand a year". Concrete numbers move decisions.
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.
On these inputs the tax-advantaged route nets the figure shown above; traditional shown alongside.
Inputs
This example uses typical values for illustration. Adjust the inputs above to match a specific situation and see how the result changes.
