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

Divide what's left to save by the months available, adjusted for interest. To reach $20,000 in 3 years starting from $2,000 at 4.5% APY, you'd need about $464 per month — interest covers roughly $1,300 of the goal.

Q: Should savings goals account for inflation?

For goals more than a few years out, yes — a $30,000 goal five years away at 3% inflation is really about $34,800 in future dollars. Either inflate the target or use a real (inflation-adjusted) interest rate.

Q: What's the best account for a savings goal?

Match the account to the timeline: high-yield savings for goals under ~3 years, CDs when the date is fixed and known, and investments only for goals 5+ years out where you can ride out downturns.

Name the number and the date — get the monthly deposit that hits it, with interest doing part of the work.

The formula behind it

The calculator finds the payment whose future value, plus the growth of what you've already saved, equals the goal:

PMT = (Goal − Saved × (1+r)ⁿ) × r ÷ ((1+r)ⁿ − 1)

where r is the monthly rate and n the number of months.

Worked example

Goal $20,000 in 3 years, starting from $2,000 at 4.5% APY:

Required deposit ≈ $464/mo. You'll deposit about $16,700; growth on your head start and deposits covers the remaining ≈ $1,300.

Hitting goals you actually keep

Savings goals fail on friction, not math. Set up an automatic transfer for the exact amount on payday; break the number down (the daily equivalent above makes a big goal feel survivable); and park the money where the timeline dictates — a high-yield account for short goals, a CD when the date is fixed, investments only for 5+ year horizons. If the required amount is more than you can swing, extend the date rather than abandoning the goal: on the example above, stretching 3 years to 4 drops the deposit from $464 to about $339.
