Retirement Calculator
Use this retirement calculator to estimate whether your current savings and future contributions may support your retirement income goal. It compares projected retirement savings with an estimated retirement need after inflation and other income sources.
The calculator includes current age, retirement age, savings, monthly contributions, expected return, inflation, income replacement goal, other monthly retirement income, retirement length, contribution increases, and a planning withdrawal rate.
What is the Retirement Calculator?
A retirement calculator is a planning tool that estimates how savings may grow before retirement and how much money may be needed to support future income. It helps answer whether a user may be on track, ahead, or facing a possible shortfall.
This calculator does not promise a retirement outcome. It uses the assumptions entered by the user, then shows projected balance, retirement need, income gap, suggested extra monthly savings, and inflation adjusted value.
Retirement savings, income gap, and inflation explained
Projected retirement balance estimates how current savings and future contributions may grow by retirement age.
Estimated retirement need is the savings target that may be needed to support the retirement income gap after Social Security, pension, or other monthly income is included.
Inflation adjusted balance shows what the future balance may feel like in today money, which is useful because prices can rise over time.
How to use the Retirement Calculator
Start with your age, retirement age, current savings, and monthly contribution. Then add income and return assumptions to estimate whether your projected savings may meet your retirement income goal.
- Enter current age and planned retirement age.
- Add current retirement savings and monthly contribution.
- Enter current annual income and the percentage of income you want in retirement.
- Add expected monthly Social Security, pension, or other retirement income if you want the calculator to reduce the savings income gap.
- Enter expected return before retirement, expected return during retirement, inflation, and planned retirement years.
- Review projected retirement balance, estimated retirement need, gap or surplus, suggested extra monthly savings, and the yearly savings projection.
How each input affects the result
Use this guide before filling the calculator. It explains what the main input areas mean, how to enter them, and how each one can change the estimate.
| Input area | What it means | Impact on result |
| Current age and retirement age | The time left before retirement. | More years usually give savings more time to compound and may reduce the monthly gap. |
| Current savings | The amount already saved for retirement. | Higher starting savings improves projected balance and reduces the estimated shortfall. |
| Monthly contribution | The amount added before retirement. | Higher contributions increase the projected balance and may lower suggested extra savings. |
| Return and inflation assumptions | Expected growth and future price increase assumptions. | Return grows the balance, while inflation lowers today-dollar buying power. |
| Desired retirement income | The income goal used for retirement planning. | A higher income goal increases estimated retirement need and may create a larger gap. |
| Other retirement income | Income from sources such as pension, benefits, or rental income. | It can reduce the amount your savings need to support. |
What your results mean
After calculating, start with the main result card, then use the detail rows to understand why the number changed. This makes it easier to compare scenarios without guessing.
| Result line | What it means |
| Projected retirement balance | Estimated future savings at retirement using your savings and contribution assumptions. |
| Inflation adjusted balance | Projected balance expressed in today-dollar buying power. |
| Estimated retirement need | Approximate savings target based on income goal and retirement years. |
| Gap or surplus | Whether projected savings are below or above the estimated need. |
| Suggested extra monthly savings | Additional monthly saving estimate to help close a projected shortfall. |
Example
For example, a user can enter current savings, a monthly contribution, a planned retirement age, an income goal, and expected inflation. The calculator can show whether projected savings may cover the retirement income gap and how much extra monthly savings may be needed if there is a shortfall.
Why use this calculator?
Retirement planning can be confusing because a future balance alone does not show whether income needs will be covered. This calculator combines savings growth and retirement income planning in one view.
- Estimates future retirement savings from current balance and contributions.
- Compares projected balance with an estimated retirement nest egg target.
- Shows a retirement income gap after other monthly income sources are included.
- Adds inflation adjusted value so future dollars are easier to understand.
- Estimates suggested extra monthly savings when the projection shows a shortfall.
- Includes yearly savings projection and retirement income need breakdown.
Best for
- Users checking if they may be on track for retirement.
- People comparing monthly contribution levels.
- Workers estimating retirement income needs before changing savings rate.
- Users who want a simple retirement planning calculator with inflation and income gap context.
- People comparing savings growth, retirement income, and possible shortfall in one page.
Pros and things to check
Potential benefits

FAQs
What is a retirement calculator?
A retirement calculator estimates how much your savings may grow and whether that amount may support your future retirement income needs.
How does this retirement calculator work?
It projects savings from current balance, monthly contributions, expected return, and time until retirement. It then compares that balance with an estimated retirement need based on income goal, inflation, other income, and retirement length.
What does projected retirement balance mean?
Projected retirement balance is the estimated savings amount at retirement age based on the inputs entered.
What does estimated retirement need mean?
Estimated retirement need is the target nest egg that may be needed to support the income gap during retirement.
Can this calculator include Social Security or pension income?
Yes. Enter expected monthly Social Security, pension, or other retirement income so the calculator can reduce the amount your savings need to cover.
Does this calculator include inflation?
Yes. It shows inflation adjusted value and uses inflation when estimating future retirement income needs.
What does suggested extra monthly savings mean?
It estimates how much more you may need to save each month before retirement if the calculator shows a shortfall.
Is the retirement calculator result guaranteed?
No. It is a planning estimate. Real results can change because of market returns, inflation, taxes, fees, healthcare costs, and withdrawal timing.
Can I use this as a retirement income calculator?
Yes. It estimates possible monthly retirement income from the projected savings balance using a planning withdrawal rate.
Should I use today dollars or future dollars?
Use current income and current monthly income estimates. The calculator applies inflation assumptions to estimate future retirement needs and also shows today dollar value.
How do I use the Retirement Calculator?
Enter the starting amount, contribution, return, inflation, cost, years, or target values requested by the tool. Use advanced assumptions only when you want a deeper comparison.
What result should I check first?
Start with the main future value, return, inflation impact, real return, retirement gap, or target result. Then review the yearly table or detail rows if available.
Can I enter zero for return, inflation, fee, tax, or contribution fields?
Yes. A real 0 should stay 0. This helps test no growth, no inflation, no fee, no tax, or no added contribution without using a hidden default.
Why can the real investment result be different?
Actual results can change because market returns, fees, taxes, inflation, timing, contribution behavior, withdrawals, and provider rules are not guaranteed.
Does this calculator include taxes and fees?
It includes taxes or fees only when the tool has fields for them. If a field is missing, treat the result as a before tax or simplified planning estimate.
Can this help compare investment scenarios?
Yes. Keep the starting amount and time period the same, then change one assumption such as return, inflation, contribution, fee, or target to see the difference.
