How much do I need to save each month to reach my goal?

It depends on the target, the time, what you have already and what it earns. For $50,000 in five years starting from $5,000 at a 4% return, the calculator solves for the exact monthly figure and shows how much of the target the growth covers rather than your deposits.

What return should I assume for a short-term goal?

A savings-account or money-market rate, not an investment return. Money you need on a date should not be somewhere it can fall 30% the quarter before. Entering an equity return lowers the monthly figure on screen and raises the chance of missing the goal in reality. If you are carrying debt at the same time, saving may lose to paying it down once tax is taken.

Should I increase my savings each year?

If your income rises, yes, and the annual step-up field models it. Escalating deposits reach the same target with a lower starting amount, which makes a plan easier to begin. The trade is that the later years demand more, so only use it if the rises are genuinely likely.

What if the required amount is more than I can save?

Three levers: lengthen the timeline, lower the target, or raise the starting balance. Lengthening usually does the most work, because it adds both more deposits and more growth on each of them. Raising the assumed return is the one lever that does not actually change anything in the world. To see the growth side on its own, use the compound interest calculator.

Does this account for inflation?

No. The target is treated as a fixed number of dollars. If you are saving for something whose price will rise, a house deposit, a car, inflate the target before entering it. The inflation calculator will give you the adjusted figure.

Why does the calculator say my goal is out of reach?

Because even a very large monthly deposit does not reach it in the time given, which usually means the timeline is too short rather than the target too big. Add a year and try again, the required deposit falls faster than the timeline lengthens.

Savings Goal Calculator

This savings goal calculator works backwards. Give it the amount you need and the date you need it, and it solves for the exact monthly deposit that gets there, allowing for what you have saved already and what it earns along the way.

Example numbers

The answerfrom an example

You need to save $662.08 a month to reach $50,000 in 5 years.

Worked on $50,000 in 5 years, $5,000 already saved, earning 4%. Change anything below to use yours.

Save each month: $662.08
Total you will deposit: $39,725
Growth does the rest: $5,275

The figures behind it

Save each month: $662.08; Held level for the whole period.
Total you will deposit: $39,725; Over 60 monthly deposits.
Growth does the rest: $5,275; 10.6% of the target is money you never had to save.
Starting balance grows to: $6,105; What you already have would become this on its own.
Ends at: $50,000; On or just above the target, which is what the monthly figure is solved for.

What this result assumes

The monthly figure is the smallest amount, to the cent, that reaches the target. Anything less falls short.
Deposits are made at the end of each month, so a deposit earns nothing in the month it is made. That is the conservative convention.
The return is held constant. For a goal a few years out, use a savings or money-market rate rather than an investment return, a portfolio that can fall 30% is not a plan for money you need on a date.
Tax on any growth is not deducted, and inflation is not applied, so the target is in today’s dollars but the balance is in future ones.

Methodology

Reviewed August 31, 2026

Solving backwards

Most savings calculators run forwards: you supply a monthly amount and they tell you where you land. This one runs the other way. You supply the destination and it finds the monthly deposit that gets there — which is the question people actually have when they are saving for a deposit, a car or a wedding on a date.

The contribution is found by bisection rather than in closed form. A closed form exists for a level deposit into a fixed rate, but not once the deposit is allowed to step up each year, and a single code path that handles both is worth more than the exactness. The search halves the interval until it is one cent wide, so the answer is the smallest whole number of cents that reaches the target — the test suite checks that one cent less falls short.

Everything downstream is then run at that contribution, so the chart, the schedule and the headline all describe the same plan rather than three approximations of it.

What the growth does

The figure worth reading is how much of the target you do not have to save. On the default scenario, growth covers several thousand dollars of a $50,000 goal — money that arrives without being deposited.

That share is small over short horizons and large over long ones, which is the practical reason short-dated goals need a different strategy from long-dated ones. Over five years, the return you assume barely changes the monthly figure. Over twenty-five, it dominates it.

Choosing a return, honestly

For a goal a few years out, use a savings-account or money-market rate. It is tempting to enter a long-run equity return and watch the required deposit fall, but a portfolio that can lose a third of its value is not a plan for money you need on a specific date. Sequence risk is not a footnote here; it is the whole problem.

The model holds the return constant and applies no volatility, so it cannot show you the range of outcomes. Treat the monthly figure as the amount that works if the assumption holds, and save more than it if the date is not negotiable.

The target is in today’s dollars while the balance is in future ones. If the goal is a real purchase several years out, inflate the target before entering it.

Assumptions

The return is constant for the whole period, with no volatility.
Deposits are made at the end of each month and never missed.
Any annual step-up applies on the anniversary, not gradually through the year.
No withdrawals are made before the target date.
Tax on interest or gains is excluded.
Inflation is not applied, so the target is nominal — it will buy less on the date than it would today.
Account fees and fund expenses are excluded.
