Savings Goal Calculator
To hit a goal, solve PMT = (goal − grown starting balance) ÷ (((1+r)^n − 1) ÷ r). Enter a target, a timeline and a return to find the monthly amount to save — or switch modes to see how long a fixed deposit takes, or where your savings will land.

The basics
Three ways to look at a savings goal
A goal has four moving parts — the target, the time, the deposit and the return. Fix any three and the calculator solves the fourth.
solve for the deposit
Backwards from a target
The most common question: I want a set amount by a set date — how much must I put away each month? Fix the goal, the timeline and the return, and the monthly deposit falls out.
$50,000 in 5 years → $662.08 a month
solve for the time or the total
Forwards from a deposit
Or fix what you can save and ask the other questions: how long until I reach the goal, and how much will I actually have? Interest is compounded monthly in every mode.
$500/mo, 4% → a balance and a date
Method
How to find the monthly amount by hand
Four steps turn a target and a timeline into a monthly number.
- 1
Set the goal and the timeline
Decide the target amount and how many years you have. Multiply the years by twelve for the number of monthly deposits n.
$50,000 in 5 years → 60 deposits - 2
Grow what you already have
Your starting balance compounds on its own over the whole period, so it covers part of the goal before you add a cent.
$5,000 at 4% for 5 years - 3
Solve for the monthly deposit
The gap between the goal and the grown starting balance is filled by the monthly deposits, rearranged from the future-value formula.
PMT = (goal − grown start) ÷ (((1+r)^n − 1) ÷ r) = $662.08 - 4
Check the split
Add up your deposits and subtract from the goal to see how much interest is doing the work — the longer the timeline, the bigger its share.
$44,725 in + $5,275 interest = $50,000
Worked examples
Monthly amount for a $50,000 goal
Starting from $5,000 at 4%. A longer timeline sharply lowers the monthly deposit, because interest has more time to help.
| Timeline | Monthly needed | You deposit | Interest earned |
|---|---|---|---|
| 3 years | $1,161.91 | $46,829 | $3,171 |
| 5 years | $662.08 | $44,725 | $5,275 |
| 10 years | $288.94 | $39,672 | $10,328 |
| 15 years | $166.19 | $34,915 | $15,085 |
Where it shows up
Goals people plan this way
Three common targets a monthly number makes reachable.
house deposit
A down payment
The classic use: a set deposit for a home by a chosen date. A monthly figure turns a daunting five-figure goal into an automatic transfer.
A fixed target by a move date
emergency fund
A safety net
Building three to six months of expenses is a goal best kept in a high-yield savings account — safe, available, and earning a little on the way.
3–6 months of expenses, kept safe
big purchase
A car, wedding or trip
Saving toward a large purchase avoids financing it later. The tool shows the monthly amount, or how long your current pace takes.
Save ahead instead of borrowing
Reference
Where to keep savings, by timeline
General guidance, not advice. The right home for the money depends on when you need it. Rates are broad bands, not a quote.
| Vehicle | Typical return | Best for | Trade-off |
|---|---|---|---|
| Checking account | ≈ 0% | Spending money | No growth, fully liquid |
| High-yield savings | A few % | Emergency fund, < 3-year goals | Rate moves with the Fed |
| Certificate of deposit | A few %, fixed | A goal with a known date | Locked up until maturity |
| Diversified investments | ~6–8% long run | Goals 10+ years away | Can fall in any given year |
Worth knowing
Five things about hitting a goal
The math is only half of it — these keep the plan on track.
automate it
Pay the goal first
Set an automatic transfer for the monthly amount, timed just after payday. Money you never see is money you do not spend.
time changes everything
Longer is cheaper
Stretching the timeline drops the monthly deposit fast, because interest carries more of the load. Start early even if the amount is small.
match the risk to the date
Near goals stay safe
Money you need within a few years should not ride the stock market. Keep short-term goals in cash or a CD so a downturn cannot derail them.
raise it with your pay
Step it up
Increasing the deposit as your income grows pulls the goal forward. Even a small yearly bump adds up over the life of the plan.
round up the number
Build in a buffer
Saving slightly more than the exact figure gives room for a missed month or a price that creeps up by the time you buy.
keep it separate
Use a dedicated account
A separate, named account for the goal stops it mingling with spending money and makes progress easy to see.

Monthly deposit at 4% annual return, no starting balance, contributions at month end.
How we calculate this
The formulas and our assumptions
Each mode rearranges the same future-value relationship.
PMT = (goal − PV·(1+r)^n) ÷ (((1+r)^n − 1) ÷ r)
Monthly needed
The deposit that fills the gap between the goal and the grown starting balance, where r is the annual return over twelve and n the months.
FV = PV·(1+r)^n + PMT·((1+r)^n − 1) ÷ r
Time and future value
Future value grows the balance and the deposits together. For “time to goal” we step the balance forward month by month until it reaches the target.
- Interest compounds monthly; contributions are added at the end of each month.
- The return is a steady average — a real invested return varies year to year.
- Figures are nominal, before tax and inflation.
- Set the return to 0% for a plain, non-interest account.

FAQ
Common questions
Work backwards with PMT = (goal − grown starting balance) ÷ (((1+r)^n − 1) ÷ r), where r is the annual return over twelve and n the months. To reach $50,000 in 5 years, starting with $5,000 and earning 4%, you need about $662.08 a month. A higher return or a longer timeline lowers that figure; the calculator solves it for your own numbers.
Switch the calculator to "Time to goal": enter the target, what you have, your monthly deposit and the return, and it counts the months until the balance reaches the goal. Saving $662.08 a month toward $50,000 from $5,000 takes about 5y 1m. A bigger deposit or a higher return gets you there sooner.
Yes. Enter the annual return and the calculator compounds it monthly. Interest can do real work: to reach $50,000 in the example you deposit only $44,725 in total — the other $5,275 comes from returns. For a plain checking account, set the return to 0% to see the pure deposit total.
It depends where the money sits. A checking account is roughly 0%. A high-yield savings account or a short CD might be a few percent. Money invested in a diversified fund is often modelled at 6–8% over the long run, but it can fall in any given year — so for a short goal you cannot afford to miss, use a low, safe rate.
Time horizon decides. For a goal within a few years — a car, a wedding, a house deposit — a high-yield savings account or CD protects the money from a market dip right when you need it. For a goal a decade or more away, investing gives the returns a chance to compound, accepting the short-term swings. Never invest money you must spend soon.
A savings account, usually from an online bank, that pays a much higher rate than a typical brick-and-mortar account — often several percent versus a fraction of one. The money stays FDIC-insured and available, which makes it a common home for an emergency fund or a short-term goal. Rates move with the Federal Reserve, so they rise and fall.
Automate it. Set up an automatic transfer for the monthly amount the calculator gives you, timed just after payday, so the money moves before you can spend it. Breaking a large goal into a fixed monthly number makes it concrete, and watching the balance climb toward the target keeps the habit going.
Yes, and it helps more than it seems. Raising your monthly deposit as your income grows means later contributions are larger, and they still have time to earn returns. Even a small annual increase can pull a goal forward by months. The retirement calculator on this site models a yearly step-up if you want to see the effect.

The Compound Interest Formula: A = P(1 + r/n)^(nt), Explained
The compound interest formula is A = P(1 + r/n)ⁿᵗ, where P is the starting principal, r is the annual rate as a decimal, n is the number of times interest compounds per year, t is the number of years, and A is the final amount. This guide defines each variable, works a full example, and shows how compounding frequency changes the result.
