Smart retirement planning

Your retirement plan should reflect how your expenses actually change.

Education costs, loan payments and commuting may disappear. Healthcare, travel or domestic help may rise. The Carrowmont Retirement Planner models those changes instead of blindly inflating today's total spending.

UNDERSTAND BEFORE YOU MODEL

Understand the retirement assumptions before you model them.

Learn how spending, inflation, retirement income and time horizon shape the amount a portfolio may need to support.

Your plan

Build the assumptions

Fast estimate: one retirement-spending percentage and one inflation rate are applied to your household total.

Why the numbers can differ: Quick Estimate is intentionally simplified. It applies one retirement-spending percentage and one inflation rate to your household total. Detailed Planner models categories separately, including different inflation rates, expenses that start/end/change, retirement income and lifestyle phases, so the results may differ.
Country & currency: changing country clears monetary amounts so values from one country are not accidentally treated as another currency. Changing currency within the same country only changes the display unit and does not perform FX conversion. Carrowmont does not automatically change inflation, investment returns, taxes, pension rules or retirement-account rules; the rates shown are editable assumptions, not country-specific forecasts.

Future-money values: this chart shows projected nominal amounts in your selected currency at each future age. They should not be compared directly with today's money without considering inflation.

How to read this chart: the green line is your projected current-plan portfolio. The blue line is the modelled required-corpus path, including your selected safety buffer.

Contribution adjustment—Additional retirement contribution indicated under these assumptions.
Largest expense change—The biggest category-level shift in today's purchasing power.
What if?

Compare retirement ages

Same assumptions, different retirement date.

Retirement target figures are shown in future money at each retirement age. A later retirement can therefore show a higher nominal corpus because of inflation, while still requiring a lower recurring retirement contribution because you have more years to save.

How it works

Built around cash flows, not a single expense number

1

Model changing expenses

Each detailed expense is inflated independently and can continue, change at retirement, end at a chosen age or start only after retirement.

2

Subtract retirement income

Pension, rent and annuity income reduce the monthly withdrawal required from the retirement portfolio.

3

Insert future goals

One-time goals that occur during retirement are inflation-adjusted to their chosen age and added to the retirement cash-flow schedule.

4

Discount every future cash flow

The engine calculates the amount required at retirement to finance the month-by-month net cash flows while the remaining portfolio earns your assumed post-retirement return.

5

Compare with your savings plan

Existing savings and recurring retirement contributions are projected to retirement to estimate the gap and the additional contribution required.

FAQ

Important questions

Why not simply inflate today's household spending?

Because many expenses change structurally. Education and loan payments may end, work-related transport can fall, while healthcare or travel can rise. Detailed mode lets you model those changes explicitly.

What does “today's money” mean?

For expense categories and one-time goals, enter what the item costs today. The planner applies the selected inflation assumption from your current age to the age when the cash flow occurs.

How should I enter a pension?

Enter the monthly amount you expect when that income begins and the age it begins. You can also give it an annual increase rate. The calculator does not estimate pension entitlement for you.

What happens if a home loan continues after retirement?

Set the expense rule to “Ends at age” and enter the actual expected payoff age. The model will include the payment during the early retirement years until that age.

Does this guarantee that the money will last?

No. The model uses constant assumptions. Actual market returns, inflation, taxes, healthcare needs and longevity can differ materially. A future version can add variable-return or Monte Carlo analysis.
