Formula Used

FV = P(1+i)^N + C × ((1+i)^N − 1)/i; at i=0, FV=P+C×N. Beginning-period contributions multiply the annuity factor by (1+i).

Model assumptions: Contributions arrive at the beginning of the modeled period. IRA comparisons use the entered gross contribution; they do not equalize the after-tax cost of funding each account.

How the formula is applied

The calculation links Current savings ($), Monthly contribution ($) and Annual return (%) to projected retirement savings. The accumulated balance is a projection under the stated contribution timing. It does not by itself establish how much sustainable retirement income it can provide. Model convention: Contributions arrive at the beginning of the modeled period. IRA comparisons use the entered gross contribution; they do not equalize the after-tax cost of funding each account.

Calculator Description

Enter Current savings ($), Monthly contribution ($) and Annual return (%) and the remaining scenario settings to review projected retirement savings with this tool. The accumulated balance is a projection under the stated contribution timing.

Project a retirement savings balance from current capital, contributions and a chosen growth horizon. Use scenarios to expose dependence on time and saving effort.

The accumulated balance is a projection under the stated contribution timing. It does not by itself establish how much sustainable retirement income it can provide.

Frequently Asked Questions

What information do I need for the Retirement Calculator?

Prepare Current savings ($), Monthly contribution ($), Annual return (%) and Years until retirement. Compare an earlier retirement date and a lower return assumption separately while keeping the saving plan visible.

Does the savings projection determine a sustainable retirement income?

The accumulated balance is a projection under the stated contribution timing. It does not by itself establish how much sustainable retirement income it can provide. Longevity, market sequence, future spending, inflation, taxes and contribution interruptions are not fully described by a constant-return balance projection.

How can I check the retirement calculator with an example?

Use the full settings in the worked-example table. They produce Projected retirement savings: 550534.01. Compare the method and units as well as the displayed number.

Which assumptions apply to this retirement calculator?

Contributions arrive at the beginning of the modeled period. IRA comparisons use the entered gross contribution; they do not equalize the after-tax cost of funding each account. Compare an earlier retirement date and a lower return assumption separately while keeping the saving plan visible.

When should I verify the retirement calculator result elsewhere?

Longevity, market sequence, future spending, inflation, taxes and contribution interruptions are not fully described by a constant-return balance projection. For a transaction or account decision, compare the inputs with the applicable statement, contract or official rules.

How to Use This Calculator

  1. Compare an earlier retirement date and a lower return assumption separately while keeping the saving plan visible.
  2. Fill in Current savings ($), Monthly contribution ($), Annual return (%) and Years until retirement. Use the field units rather than copying an unlabeled value.
  3. For a result check, reproduce the example beginning with Current savings ($) = 25000 and Monthly contribution ($) = 500; copy the remaining settings from the detailed guide.
  4. Use the page's Calculate or Convert control, or read the updated result where the tool recalculates automatically. Locate Projected retirement savings and any supporting breakdown.
  5. Interpret the result with this distinction in mind: The accumulated balance is a projection under the stated contribution timing. Keep the selected inputs alongside the output when comparing scenarios.

Practical example and result check

Worked retirement calculator example. Set Current savings ($) = 25000; Monthly contribution ($) = 500; Annual return (%) = 7; Years until retirement = 25. The corresponding output is Projected retirement savings: 550534.01. The accumulated balance is a projection under the stated contribution timing.

Before relying on the result

  • Confirm the units, dates, rates and time periods entered.
  • Review which costs, measurements or assumptions are included and excluded.
  • Change one important input at a time to understand the result sensitivity.

Follow the calculation

Relationship used for this example: FV = P(1+i)^N + C × ((1+i)^N − 1)/i; at i=0, FV=P+C×N. Beginning-period contributions multiply the annuity factor by (1+i).

The accumulated balance is a projection under the stated contribution timing. It does not by itself establish how much sustainable retirement income it can provide.

Assumptions for this model: Contributions arrive at the beginning of the modeled period. IRA comparisons use the entered gross contribution; they do not equalize the after-tax cost of funding each account.
