Savings Goal Calculator

When to use this

You have a specific financial target — $15,000 for an emergency fund, $40,000 for a down payment, $5,000 for a vacation — and need to know exactly how much to save each month to get there on time. Enter your goal amount, how much you've already saved, your timeline, and the interest rate on your savings account. The calculator tells you the precise monthly contribution required.

It works in the other direction too. If you can only set aside $600 a month, how long until you reach $30,000? Or if you have 24 months and can save $800/month, what's the maximum goal you can realistically hit? Playing with the inputs helps you find a plan that fits your budget and timeline rather than guessing or hoping.

This is also a planning tool. Turning a large target into a monthly contribution makes the tradeoff between goal size and timeline concrete. You can enter the annual interest rate currently offered by your account to see how the estimate changes, then update that rate whenever the provider changes it.

Good to know

The formula solves for monthly payment: PMT = (FV - PV x (1+r)^n) x r / [(1+r)^n - 1]. FV is your savings goal, PV is your current savings, r is the monthly interest rate (APY / 12), and n is the number of months. Your current savings compound while you add new money each month, so even a modest starting balance helps.

Interest assumptions matter more for longer goals. Compare the result at 0% with the annual rate currently offered by your account. Savings rates can change, so the result is an estimate rather than a guaranteed return. Revisit the plan when your account rate, goal, or timeline changes.

The 50/30/20 budget gives you a savings baseline. Allocate 50% of after-tax income to needs, 30% to wants, and 20% to savings and debt repayment. On a $4,500/month take-home pay, that's $900/month for savings goals. If your calculator result exceeds your 20% allocation, you may need to extend the timeline or reduce the goal.

Automate it. Research consistently shows that automatic transfers on payday are the most effective savings strategy. Set up a recurring transfer for the exact amount the calculator shows, and treat it like a non-negotiable bill. People who automate savings reach their goals at significantly higher rates than those who transfer manually.

Build the emergency fund first. Financial planners almost universally recommend saving 3–6 months of essential expenses before targeting other goals. Without this cushion, an unexpected expense (car repair, medical bill, job loss) forces you to raid your savings goal or take on debt, setting you back further than if you'd built the safety net first.
