How to use the save to buy calculator

  1. Enter the price of what you want to buy and how much you've already saved.
  2. Add how much you can set aside each month.
  3. Set how fast the price tends to rise each year. Use 0% if it stays the same.
  4. Optionally add an expected return if you'll invest the savings. Leave it at 0% for cash.

How it's calculated

The calculator runs month by month. Each month your savings grow by the monthly return (if any) and your monthly amount is added, while the price rises by the yearly price increase spread across the months:

Savingsm = Savingsm−1 × (1 + i) + Monthly

Pricem = Price × (1 + g)m ÷ 12

The first month when your savings reach the price is when you can buy.

Example

Want a $25,000 car? With $5,000 already saved and $600 a month set aside, and car prices rising 3% a year, you could pay cash in about 3 years and 2 months, when the car costs about $27,453. If the price didn't rise it would take 34 months.

Tips

  • Paying cash means the sticker price is the whole price: no extra charges and no monthly bill afterwards.
  • Set up an automatic transfer on payday so your monthly amount is saved first.
  • A slightly older or smaller model can cut months or years off your timeline.
  • Keep your emergency fund separate so a surprise bill doesn't reset your progress.

Frequently asked questions

Is it better to save up or finance a purchase?
Saving up means you pay only the price and own the item outright from day one, with no ongoing payments. The trade-off is waiting. This calculator shows exactly how long that wait is.
What if the price goes up while I save?
Enter a yearly price increase. The calculator raises the target a little every month so your date reflects what the item will cost when you're ready to buy.
How can I reach my goal sooner?
Increase your monthly amount, put windfalls like bonuses toward the goal, sell things you no longer need, or choose a less expensive option. Try different numbers above to see the effect.
Where should I keep the money while I save?
For purchases within a few years, somewhere stable and easy to reach is usually best, since investments can lose value right when you need the money.
