Savings Goal Calculator
Find out how much you need to save monthly to reach your financial goal.
Savings Goal Math — Target Date Formulas
Three ways to hit the same goal: start with a lump sum (PV), contribute monthly (PMT), or blend both. The calculator's monthly-contribution formula is the annuity future value; rearranged, it tells you the exact monthly deposit for any target and timeline.
Rate choice changes the deposit more than most people expect: at 0% you'd need the raw goal ÷ months; at 5% APY, the account's own growth covers an increasing share, especially over long horizons.
Worked Example: $20,000 Emergency Fund in 3 Years
At 0%: 20,000 ÷ 36 ≈ $555.56/month
At 4.5% APY (0.375%/mo): PMT = 20,000 × 0.00375 ÷ (1.00375^36 − 1) ≈ $521.60/month
Growth does ≈ $34/month of the work — $1,220 over the term
With a $5,000 start: remaining goal $15,000 → ≈ $389/month
A starter lump sum beats rate-shopping: the $5,000 seed cuts the required monthly by $132, while 1 extra point of APY cuts it by only ~$25.
Frequently Asked Questions
How much should an emergency fund hold?
Standard guidance: 3-6 months of essential expenses (rent, food, insurance, minimum debt payments). Self-employed or single-income households should sit at 6+ months. Keep it in a high-yield savings account, not invested — the job is stability, not growth.
High-yield savings vs CDs vs bonds for short-term goals?
Under 1 year: HYSA (liquid, rate tracks the Fed). 1-3 years: CD ladder or Treasuries lock the rate. Only goals 5+ years away belong in stocks, where short-term dips can wreck a deadline.
Is it better to save or invest extra cash?
Split by purpose: emergency fund and near-term goals in savings; retirement and 5+ year goals in investments. The savings calculator answers 'when do I hit the number'; the investment calculator answers 'what could it become'.
Why does my bank's APY differ from its rate?
APY includes compounding (a 4.45% rate compounds to ~4.55% APY monthly). Compare accounts by APY only — it is the true annual yield — and confirm whether the APY is promotional for a limited balance tier.

Common Mistakes & Pro Tips
Avoid these mistakes
Assuming the teaser rate lasts
Introductory savings rates ('4.5% for 3 months') reprice quarterly with the central-bank cycle. Planning a year of interest on the teaser number overestimates earnings by most of the year's rate drift — model the repriced rate instead.
Ignoring monthly vs annual compounding
A '5% savings account' compounded monthly earns 5.12% effective. On 25,000 that is about 130 more per year than annual compounding — free money if you choose the monthly account, pure loss if you ignore the frequency.
Forgetting the goal date
A savings goal without a deadline has no required monthly deposit. 10,000 in 3 years at 4% needs about 262 per month; in 5 years only 151. Set the date first — the calculator returns the required saving rate, not a vague hope.
Pro tips
Pay yourself first, automatically
Automate the transfer the day after payday. Behavioral studies consistently show automated savers accumulate far more over two years than intention alone — the monthly-deposit field is the plan; the standing order is the execution.
Compare APY, not rate lists
APY folds compounding frequency into one comparable number. A 4.50% APY monthly account beats a 4.55% account compounding annually less often than you'd guess — always read the APY figure, never the marketing rate.
Round deposits up
Rounding 262 to 275 per month finishes 2–3 months early at trivial cost — a buffer against the month you must skip. The savings calculator shows the exact finish date either way; rounding up buys insurance.
