Retirement Cost of Living Estimator
Projected Monthly Cost
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.
