Finance tool
Savings goal calculator
Enter a savings goal and either your monthly contribution or target date — see how long it takes, or how much you need to save each month.
Start with the free manual tool. If you want the real document view after that, analyze a statement PDF.
Free tool
How long will it take to save what you need?
Pick a mode. Enter your goal, starting balance, monthly contribution (or target months), and interest rate. The calculator computes time to goal, total contributions, and interest earned live.
Savings goal inputs
Pick a mode. "Time to goal" assumes a fixed monthly amount and computes the months. "Monthly needed" assumes a target date and computes the monthly contribution.
Total amount you want to save.
What you already have saved.
How much you'll add each month.
APY on your savings account. HYSAs often yield 4-5% as of 2026.
Contributing $500/month at 4.5% APY will hit $25,000 in 41 months.
Target you're saving toward.
10.0% of goal already saved.
Principal you'll add over time.
4.5% APY compounded monthly.
Balance after n months = Starting × (1 + r)^n + Monthly × [((1 + r)^n − 1) / r]
where r = annual rate / 12
Natural next step
Is the monthly number realistic?
Knowing how much to save per month is only half the job. Upload your bank statement to see your current cash flow — then you'll know whether that monthly number is realistic or needs to come from somewhere else.
What it gives you
Fast enough for a first pass
Each tool is intentionally narrow. The job here is a clean estimate, not a fake replacement for a full statement analysis.
Bi-directional solver
Toggle between 'time to goal' and 'monthly needed' modes — see both sides of the equation.
Compound interest included
Includes compound interest at monthly compounding — important for multi-year goals at HYSA rates.
Contribution vs yield split
Separates total contributions from interest earned so you see exactly how much of the goal came from saving vs yield.
When it's useful
A single-goal savings planner with compound interest — no signup, runs in the browser.
Anyone with a concrete savings target
Emergency fund, house down payment, wedding, vacation, car — any goal with a specific dollar amount and timeline fits this calculator.
People deciding between more months or more monthly
Toggle between 'time to goal' and 'monthly needed' to see how flexing one variable changes the other. Helpful for budget conversations.
Couples planning joint savings
Combine both partners' monthly contributions in one input to model a joint goal. The shared monthly number is usually higher than either person expects.
Anyone comparing a HYSA to a regular savings account
Run the same scenario at 0.5% (traditional) and 4.5% (HYSA) — the difference over 36-60 months is usually the deciding factor.
Deeper context
How to pick a realistic monthly contribution
The calculator tells you the math. Your bank statement tells you whether the math fits your life.
Start with your actual savings rate, not a wish
Look at the past 3 months of bank statements. What percent of take-home pay actually reached savings? That's your baseline. The savings goal calculator is most useful when you enter your real number, not an aspirational one.
Split the goal between cuts and additions
If the monthly number comes out higher than your current pace, decide how much comes from spending cuts vs income increases. Both are valid. Neither alone is usually enough.
Automate the number once it's set
Once you've picked a monthly contribution, set up an automatic transfer on payday. Manual savings fails at about 40%; automated savings succeeds at about 85% in practice.
Deeper context
Where most savings plans go wrong
A few predictable mistakes turn a solid goal into a missed one.
Using too optimistic an interest rate
Quoting 7-10% from stock-market averages to a 12-month goal is a mistake — short-term returns are volatile and could be negative. Use HYSA-like rates (4-5%) for goals under 5 years.
Forgetting the starting balance
If you already have $3,000 saved, your goal isn't the full $25,000 — it's the $22,000 gap. The calculator surfaces this by taking starting balance as its own input.
Not re-running the calc when your situation changes
Rerun the calc every 3-6 months as income, rates, or contributions change. Goals you plan once and never revisit almost always drift.
