Investment Goal Planner — Calculate Your Required Monthly Savings
Planning for a major financial milestone? Whether you are aiming for a million-dollar retirement portfolio, saving for a child’s college tuition, or building a down payment for your dream home, our free Investment Goal Planner helps you reverse-engineer your success.
Instead of guessing how much your current habits will yield, this tool flips the math. Simply enter your target amount and your timeline, and our calculator will tell you exactly how much you need to invest each month to cross the finish line.
By factoring in your current savings and expected market returns, this planner shows you the true power of compound interest. You will see a clear breakdown of how much of your goal comes from your own out-of-pocket contributions versus how much is generated purely by market growth.

Frequently asked questions
What is a realistic annual return to use?
If your money is invested in the broader stock market (such as an S&P 500 index fund), historical data suggests an average annual return of 7% to 10% over the long term. If you prefer lower-risk investments like bonds or high-yield savings accounts, you should use a more conservative rate, such as 4% to 5%.
Why does the calculator say my required monthly contribution is $0?
If you see a $0 requirement, congratulations! It means your “Initial Investment” is already large enough that compound interest alone will carry it to your target goal within your specified timeline, without you needing to add another dime.
How does compound interest reduce my out-of-pocket costs?
Compound interest is the concept of earning “interest on your interest.” Over long periods, the money your investments earn begins to generate its own earnings. As shown in our wealth breakdown chart, a significant percentage of your final goal will actually come from market growth, drastically reducing the amount of cash you have to contribute yourself.
What should I do if the required monthly investment is too high?
If the required monthly contribution doesn’t fit your current budget, you have a few options: you can extend your timeline (giving compound interest more years to work), try to increase your initial upfront investment, or slightly lower your target goal to a more manageable number.
