How it works
pension vs lump sum calculator takes your inputs and produces pension npv at break-even, lump sum grown to break-even, better option. Compare accepting a pension annuity versus taking a lump sum from your employer retirement plan. You provide 5 inputs: Monthly Pension Benefit (currency, in dollars) (default: 2500 dollars); Lump Sum Offered (currency, in dollars) (default: 400000 dollars); Current Age (number) (default: 62); Investment Return % (percent, in percent) (default: 6 percent); Expected Break-even Age (number) (default: 80). The calculator returns 3 outputs: Pension NPV at Break-even (the primary result); Lump Sum Grown to Break-even (a secondary output); Better Option (a secondary output). Investment calculations rest on a few variables — principal, return rate, time, and compounding — but their interaction is non-linear enough that intuition alone gets the answer wrong more often than not. This tool runs the real formula with your inputs and shows the numbers that matter, not the rounded approximations from a textbook. With the default values, pension npv at break-even is computed from the interaction of every input field — change any one of them and the result updates immediately, so you can stress-test different scenarios without re-entering the whole form. Adjust the inputs to match your real financial situation. The defaults are realistic starting points, but every person's circumstances differ — your actual income, expenses, rates, and timelines will produce a different answer. Use the tool iteratively: start with the defaults, then change one variable at a time to see which factor has the largest impact on your outcome.Tips
- Start with the default values to see a baseline result, then change one input at a time to understand which factor matters most for your outcome.
- Replace every default with your actual number — estimates and rules of thumb produce estimates, not answers. Pull your real figures from pay stubs, statements, or account dashboards.
- Use a conservative return rate (5-6% rather than the historical 10%) for planning purposes. Markets have long flat stretches, and planning on the average sets you up for a shortfall.
Frequently asked questions
Should I take a lump sum from my pension?
If healthy with family longevity: pension. If terminal illness or poor health: lump sum. If good investor: lump sum may grow faster. Average break-even: 78-82 years.
What does the pension vs lump sum calculator calculate?
It takes monthly pension benefit, lump sum offered, current age, investment return %, expected break-even age as inputs and computes pension npv at break-even, lump sum grown to break-even, better option. The primary output is pension npv at break-even. Compare accepting a pension annuity versus taking a lump sum from your employer retirement plan.
How accurate are the calculator results?
The math is exact — the same formulas a financial professional would use by hand. The precision of the output depends entirely on how realistic your inputs are. Use your actual numbers rather than estimates when possible. The defaults are reasonable starting points, but your real income, rates, and timeline will produce a different result.
