Time affects compounding
The earlier you begin, the more months your money has to potentially earn returns and then earn returns on those returns. Time is often as important as the monthly amount you save.

This is a simplified illustration using monthly compounding and the assumptions you entered. Investment returns, fees, taxes, inflation, withdrawals, and contribution limits can materially change real outcomes.
How it works
Plan for the retirement you want
This Retirement Savings Calculator projects a potential account balance by combining your current savings, recurring monthly contributions, expected annual return, and time until retirement.
It is an educational planning tool, not a prediction or financial recommendation. Use a range of return assumptions and revisit your inputs regularly as your income, goals, and personal circumstances change.
Regular contributions matter
Adding money every month turns saving into a routine. Even modest contributions can accumulate over long periods, especially when you raise them gradually as your income grows.
Returns are only estimates
An expected return is an assumption used for planning. Real investments can rise or fall, and annual returns vary. Test more than one rate instead of relying on one optimistic number.
Review your plan regularly
Your retirement target can change with lifestyle, health, family needs, inflation, and career shifts. Revisiting contributions and expected retirement age helps keep your plan aligned with reality.
Frequently asked questions
The calculator starts with your current savings and then models monthly growth until your retirement age. Each month, the balance earns a portion of your expected annual return and receives your monthly contribution. If you enter a yearly contribution increase, the monthly amount rises once per year in the projection.
No. The result is not guaranteed. It is a mathematical estimate based on the return rate and contribution pattern you enter. Real results may be higher or lower because markets fluctuate and because fees, taxes, inflation, withdrawals, and changes to your savings rate are not fully predictable.
There is no single right number. Some people compare several scenarios such as a conservative, moderate, and optimistic rate. The key is to understand that higher assumed returns create larger projected balances, but they also come with greater uncertainty. Consider using assumptions that fit your portfolio and time horizon.
The calculator shows 4% of the projected retirement balance as a simple annual-income reference. It does not guarantee that this amount will be sustainable. Retirement income depends on spending, market returns, inflation, taxes, other income, retirement duration, and how your investments are allocated.
No. The displayed balance is a future-dollar estimate and does not automatically reduce purchasing power for inflation. To think in today's buying power, you can use a lower real return assumption or separately compare the result against an inflation estimate.
Yes. Enter a percentage under yearly contribution increase. For example, entering 3% means a $500 monthly contribution becomes approximately $515 per month after one year, then increases again in the next year. This can model raises or a planned step-up in saving.
