Savings Goal Calculator
See how long it will take to reach any savings goal at your current pace, or what it would take to get there on a specific timeline instead.

This assumes a steady rate of return and steady contributions. A real savings or investment account's actual return will vary from month to month.
- Works for any savings goal — a vacation, a wedding, a car, an emergency fund, or anything else with a dollar target.
- Shows both the time to reach the goal at the current contribution, and the contribution needed for a specific timeframe instead.
- Optionally names the goal so the results feel personal rather than generic.
- Optionally models a contribution that grows every year, e.g. with a raise.
How to use this calculator
Optionally name the goal, then enter the target amount, what's already saved, the planned monthly contribution, and an expected rate of return on wherever the money sits. The target timeframe field shows what the current contribution is projected to grow to by that point, and — if that falls short — exactly what contribution would be needed instead to hit the goal right on schedule.
How the projection works
This uses the same compound-growth math as any savings projection: existing savings grow at the return entered, and each month's contribution is added and then also has time to grow before the goal date arrives.
Future value = (current savings × growth factor)
+ (monthly contribution × annuity growth factor)
Working the formula in reverse — solving for the monthly contribution instead of the ending balance — is how the "contribution needed for your timeframe" figure is calculated.
A worked example
Saving $15,000 for a wedding, starting from $2,000 already saved, contributing $500 a month at a 3.5% return, is projected to reach the goal in about 25 months — a little over two years. Targeting a one-year timeframe instead would require a substantially higher monthly contribution, which the calculator shows directly.
Where to actually keep this money
The return rate assumption matters a great deal for how this projection plays out, and it should reflect where the money actually sits. For a goal within the next few years, that typically means a high-yield savings account, a money-market fund, or short-term CDs — not the stock market. A goal that needs to be available on a specific date is a poor candidate for an investment that could be worth meaningfully less exactly when the money is needed.
Assumptions and limitations
- The rate of return is held flat. A real savings account's rate can change, and any market-based account will fluctuate — this shows a single steady-rate projection, not a range of outcomes.
- No taxes on interest earned are modelled. Interest in a standard savings account is taxable income in the year it's earned.
- The required-contribution figure assumes a flat contribution for the target timeframe, even when an annual increase is modelled for the main projection.
Common mistakes
Chasing a higher return with a near-term goal's savings. The purpose of this money is to be there, in full, on a specific date — not to maximize growth. A market downturn shortly before the goal date can undo months or years of saving.
Setting a single big number instead of a monthly target. Breaking a goal into a specific monthly contribution, as this calculator does, tends to make it far more actionable than a large total figure on its own.
Not revisiting the plan as the goal changes. A fixed dollar target set today (a trip's estimated cost, a wedding budget) can drift as plans firm up — revisiting the numbers every few months keeps the target realistic.
Frequently asked questions
Yes — the math is the same regardless of what the goal is for. Enter the target amount, current savings, contribution, and expected return, and optionally name the goal for a more personal result.
For a goal within the next few years, a high-yield savings account, money-market fund, or short-term CDs are the typical choices — priorities are safety and availability on a specific date, not maximizing return.
The calculator shows the monthly contribution that would be required — if that's not realistic, the honest options are to extend the timeframe, lower the target amount, or find additional income to put toward the goal.
Yes, slightly — a dollar contributed earlier has more time to grow before the goal date, though the effect is smaller over a short timeframe like a year or two than it would be over decades.
Many people find an automatic transfer on payday more reliable than a manual one made later, since it removes the decision each month — though this calculator's math works the same either way.
No — interest earned in a standard taxable savings account is generally taxable income in the year it's earned, which isn't factored into the projection shown here.
