A practical comparison for single Irish workers trying to turn a simple rule-of-thumb ("save EUR500 a month" vs "save EUR1,000 a month") into a retirement plan that accounts for rent pressure and market uncertainty.
This scenario follows a mid-30s renter with a starter cash buffer and compares three saving patterns: a lower steady contribution, a phased step-up as earnings improve, and a stronger steady contribution. It then tests those paths across weaker, central, and stronger long-run real-return environments so you can separate saving discipline from market luck.
The retirement budgets range from a lean renter setup to a more comfortable renter lifestyle. Each variant includes EUR1,297/month from age 66 as a maximum-rate State Pension (Contributory) planning anchor, but your payment will depend on your PRSI record.
The key point is not that one figure is magically "enough"; it is whether the retirement lifestyle you target can clear the model's 60-month reserve target.

Planned budget vs 60-month target
What this means
Base · EUR500
lean renter budget, barely above target
This lean path finishes only about EUR2/month above the model's 60-month reserve target, so it has virtually no margin for weaker assumptions.
Pessimistic · EUR500
lean renter budget, below target
Weaker long-run returns push this lean plan below the 60-month reserve target.
Optimistic · EUR500
lean renter budget, above target
At a 4.15% real return, this case ends with about 14.6 years of planned expenses—substantial room, but still a bounded planning case rather than a prediction.
Base · Step-up
mid-range renter budget, above target
With the central return assumption, phasing contributions upward in mid-career supports the planned mid-range renter budget.
Pessimistic · Step-up
mid-range renter budget, below target in weak markets
The phased saver stays solvent, but weak returns leave the planned budget about EUR183/month short of the five-year reserve target.
Optimistic · Step-up
mid-range renter budget, above target
At a 3.95% real return, this case ends with about 14.5 years of planned expenses, keeping the upside useful without assuming an unlimited end-of-plan surplus.
Base · EUR1000
EUR3,100 budget plus later housing support, above target
The higher steady path supports the budget and an extra EUR833/month of rent and housing support from ages 78-89, with about EUR155/month of room above the reserve target.
Pessimistic · EUR1000
EUR3,100 budget plus later housing support, below target
The path stays solvent, but weak returns leave the combined planned spending about EUR308/month short of the five-year reserve target.
Optimistic · EUR1000
EUR3,100 budget plus later housing support, above target
At a 3.65% real return, this case funds the later housing support and ends with about 14.5 years of expenses at the core EUR3,100/month budget.
All figures are real (inflation-adjusted) euros, i.e. think "today's money". The simulator tracks investable assets only; it does not count home equity.
Read the table as a planned-budget-vs-reserve-target check, not a promise that every row is safe. Within each saver path, the cash flows and costs are identical, so the weaker, central, and stronger rows isolate the effect of the return assumption. The stronger assumptions are deliberately bounded at 4.15%, 3.95%, and 3.65% real for the EUR500, Step-up, and EUR1000 paths respectively, so none finishes with more than 15 years of its end-of-plan core expenses. The lower steady path is intentionally lean: weaker markets miss the reserve target, the central case only just clears it, and the stronger case creates more room. The phased path improves the central result, but its pessimistic row still falls short of the five-year reserve target by about EUR183/month. The higher steady path clears the target in the central and stronger cases after including its later housing support, while its pessimistic row misses by about EUR308/month.
Daft's Q4 2025 Rental Report puts the average listed rent for a Dublin one-bed at EUR1,931/month, compared with about EUR1,159 in Munster. A rough EUR2.9k-EUR3.5k/month take-home range, derived from CSO gross median earnings rather than published net-pay data, shows why automating EUR500 can be difficult in Dublin without sharing, while EUR1,000 usually needs either higher earnings or cheaper housing.

This pack helps you answer three practical questions: how far a lower-but-steady monthly pension saving habit can take you, how much later step-ups improve the picture, and how badly weaker long-run returns would squeeze the plan.
For many single workers, the real split is not just EUR500 versus EUR1,000. It is often Dublin solo rent versus sharing, or Dublin versus a lower-cost region. With the Daft report putting a Dublin one-bed around EUR1,931/month, keeping EUR500 automated can already be the hard part on median pay. In a cheaper region or a house-share, that same transfer becomes much more realistic. In real life, housing costs largely determine whether you can sustain the transfer; in this model, the contribution you choose and the return assumption drive the projected result.
To keep the comparison focused, this scenario does not try to model your entire working-life budget. Instead, it uses your retirement saving capacity (what is left after rent and living costs) plus a set of illustrative stress tests and later-life goals:
Moving + setup costs (deposit, furnishings, fees)
Two car replacement events
A job-interruption buffer draw
Accessibility and care stresses in later life
An extra EUR833/month of rent and housing-support spending from ages 78-89 in every EUR1,000 variant (about EUR120,000 in total); this is consumed housing expenditure, not a ring-fenced asset or a forecast of typical Irish costs
Those events test how interruptions and extra goals change the projection instead of assuming every monthly transfer happens smoothly.
Retirement spending is planned as a monthly core budget, topped up by the State Pension entry. The EUR1,000 path also spends an extra EUR833/month on rent and housing support from ages 78-89; because that money is actually spent, no separate reserve asset remains outside the projection. If Safe/mo is at least the full planned spending shown by the projection, the plan finishes at age 90 with the targeted five years of expenses; if it is lower, the variant misses that reserve target. Age 90 is a conservative longevity stress horizon rather than a life-expectancy forecast; the research anchor for Ireland is 82.9 years. This is a model check, not a guarantee against every market, rent, care, or policy shock. The pessimistic EUR1,000 path stays positive but lands with about EUR88k (~2.4 years of core expenses), below the five-year target. Even the upside cases are capped below 15 terminal years; treat their balances as stress-test outputs, not forecasts.
When you open the preset, treat it as a starting framework and adjust only what differs from your situation:
If you are starting from MyFutureFund or a basic workplace pension, do not assume the default contribution rate gets you to the headline numbers here. The early-phase percentages are modest on typical pay, so many readers who want a true EUR500 or EUR1,000 monthly retirement-saving habit will still need extra PRSA or AVC contributions on top.
Replace the savings amount with what you can actually automate today (and add step-ups when you expect pay rises).
If you expect a career break, add a longer income pause or a bigger buffer draw.
Calibrate retirement spending to your real housing plan (renting, owning, downsizing) and healthcare expectations.
If you know your State Pension record is incomplete, lower the pension entry to avoid overconfidence.
State Pension age: The State Pension (Contributory) is generally available from age 66. This scenario uses the maximum personal rate as a planning anchor; your own entitlement depends on your PRSI contribution record.
Auto-enrolment (MyFutureFund): The system launched 1 Jan 2026 with phased contribution rates. For most earners, early-phase default contributions are much smaller than EUR500-1,000/month, so this scenario treats EUR500/EUR1,000 as a total retirement-saving target (e.g., PRSA/workplace pension + additional saving).
Dublin vs elsewhere: Rent is the dominant affordability lever. Daft's Q4 2025 report shows a Dublin 1-bed at ~EUR1,931/month versus ~EUR1,159 in Munster; a Dublin double room in a house averaged EUR876 without an en suite and EUR1,025 with one. So the real-life question is often "can I keep EUR500 automated while renting in Dublin?" before it becomes "can I reach EUR1,000?".
