Frequently Asked Questions
What should I use for 'expected annual return'?
Use 0% for money in a checking account, 2-3% for high-yield savings, 4-6% for bonds or conservative investments, 7-10% for diversified stock portfolios. Conservative is safer for goal-setting.
Does this account for taxes on investment returns?
No. The calculator shows gross returns. In taxable accounts, your net return will be lower. Consult a tax professional for your situation.
Can I change my contribution amount later?
Yes. This tool shows what you need NOW. If circumstances change, recalculate with new assumptions.
What if I can't save that much per month?
Adjust your timeline (months) upward or reduce your goal. The tool will recalculate the required contribution.
Does this plan adjust for inflation?
No. The amounts are in today's dollars. For inflation-adjusted planning, reduce your expected return by estimated inflation (e.g., 5% return minus 2.5% inflation = 2.5% real return).
Can agents call this tool deterministically?
Yes. The route publishes `savings_goal_calculator` with a stable v1 contract.
Is this tool free and private to use?
Yes. AI Fin Hub tools are free, no-signup browser tools. Inputs stay in your browser unless you choose to share a URL.
Can I use this with AI agents too?
Yes. Human mode is the default experience. If you use AI automation, open the optional 'For AI Agents' section for deterministic contracts.
Is this professional advice?
No. Outputs are planning estimates only — not financial, tax, or investment advice.
