Projected Monthly Cost

Future Monthly Budget (At Retirement) $0 Equivalent to current $0/mo lifestyle
Cost Breakdown (Future Dollars)
Essential Living (3%): $0
Discretionary (3%): $0
Healthcare (5%): $0
Total Monthly: $0
Annual Income Required $0
Est. Portfolio Needed (4% Rule) $0 Does not account for Social Security offsets.
Inflation Impact: Notice how healthcare costs grow disproportionately if you set a higher inflation rate for them. This calculator assumes compounding annual inflation over the “Years Until Retirement” period. The “Portfolio Needed” figure is a gross estimate based on the 4% withdrawal rule (25x annual expenses).

What Is a Cost of Living in Retirement Calculator?

A Cost of Living in Retirement Calculator estimates how much money you will need each month and year once you retire, adjusted for inflation.

Instead of guessing, it uses:

  • Your current monthly expenses
  • The number of years until retirement
  • Expected inflation rates
  • Separate growth assumptions for healthcare costs

The goal is simple. It answers one core question:

“If I want to live the same lifestyle in retirement, how much will it actually cost?”


Why Retirement Costs Are Hard to Estimate

Many people underestimate retirement expenses because they think costs go down after work stops. Some expenses do drop, but others rise.

Common surprises include:

  • Healthcare and insurance costs increasing faster than normal inflation
  • Housing expenses lasting longer than expected
  • Travel and leisure spending rising in early retirement
  • Inflation quietly reducing purchasing power over time

A calculator like this helps bring those hidden factors into the open.


How This Retirement Cost Calculator Works

This calculator is designed to be realistic but easy to use. It focuses on three main areas: timeline, inflation, and expenses.

Let’s break it down step by step.


1. Years Until Retirement

This input sets the timeline for inflation to work.

If you plan to retire in:

  • 10 years, inflation has less time to compound
  • 30 years, inflation has a much bigger impact

Even small inflation rates grow into large numbers over long periods. This calculator applies compounding inflation every year until retirement.


2. Inflation Assumptions (Why There Are Two Rates)

General Inflation

This applies to most everyday expenses like:

  • Housing
  • Food
  • Utilities
  • Transportation
  • Entertainment

The calculator defaults to 3%, which matches long-term historical averages.

Healthcare Inflation

Healthcare costs usually rise faster than normal living expenses.

This includes:

  • Insurance premiums
  • Out-of-pocket medical costs
  • Long-term care planning

The calculator uses a higher default rate of 5% to reflect this reality.

Separating these two inflation rates makes the projection far more realistic.


3. Monthly Expense Categories (Today’s Dollars)

The calculator asks for expenses in today’s dollars, not future dollars. This keeps things simple and relatable.

Essential Living Expenses

These are your non-negotiables:

  • Housing
  • Groceries
  • Utilities
  • Transportation
  • Basic daily needs

Discretionary Expenses

These support your lifestyle:

  • Travel
  • Hobbies
  • Dining out
  • Entertainment

Healthcare and Insurance

This includes:

  • Medicare premiums
  • Supplemental insurance
  • Prescriptions
  • Expected out-of-pocket costs

Each category grows independently based on the appropriate inflation rate.


What the Calculator Shows You

Once you click “Project Future Costs”, the calculator provides several key outputs.


Future Monthly Cost at Retirement

This is the most important number.

It shows how much your monthly lifestyle will cost at retirement age, adjusted for inflation. It also shows what that future lifestyle equals in today’s dollars, helping you compare apples to apples.


Detailed Cost Breakdown

You see how much each category contributes to the total:

  • Essential living costs (inflated at the general rate)
  • Discretionary spending (also general inflation)
  • Healthcare costs (inflated at the higher medical rate)

This breakdown highlights how healthcare can quietly become one of the largest expenses in retirement.


Annual Income Required

The calculator converts your monthly total into an annual figure. This number is useful for:

  • Comparing against pensions
  • Estimating Social Security gaps
  • Planning withdrawals from investments

Estimated Retirement Portfolio Needed (4% Rule)

The calculator applies the 4% rule, which estimates how much savings you may need to safely fund retirement.

The formula is simple:

  • Annual retirement expenses × 25

This gives a rough estimate of total retirement savings needed to support your projected lifestyle.

Important note:
This estimate does not subtract Social Security or other income sources. It is intentionally conservative.


Why This Calculator Is Useful for Planning

This tool is not about predicting the future perfectly. It is about improving decisions today.

It helps you:

  • See the long-term impact of inflation
  • Understand how healthcare costs affect retirement planning
  • Test different spending levels
  • Adjust retirement timelines realistically

Small changes now can have a big effect later.


How to Use the Results Wisely

Think of the output as a planning guide, not a promise.

Good next steps include:

  • Comparing the results with your current savings
  • Running different scenarios with higher or lower expenses
  • Adjusting retirement age assumptions
  • Reviewing healthcare assumptions carefully

Using the calculator once is helpful. Revisiting it regularly is even better.
