Return Assumptions for Short-Term Goals
Return assumptions and vehicle selection for short-term investment goals (2025)
| Time Horizon | Appropriate Vehicle | Expected Return 2025 | Risk Level | Right Calculator Rate |
|---|---|---|---|---|
| Under 1 year | HYSA or T-bills | 4.5 to 5.0% | None (FDIC) | 4.5% |
| 1 to 2 years | HYSA or short-term CD | 4.0 to 5.0% | None (FDIC) | 4.5% |
| 2 to 3 years | HYSA or CD | 4.0 to 4.75% | Minimal | 4.25% |
| 3 to 5 years | HYSA or CDs plus small stock allocation | 4.0 to 5.5% | Low to moderate | 4.5% |
| 5 to 7 years | Moderate mix: 40 to 60% stocks | 5 to 6% | Moderate | 5.5% |
Using 8% to 10% equity return assumptions for money needed in 2 to 3 years is a planning error. The S&P 500 has fallen 30%+ in 12 months multiple times. If you need $50,000 for a down payment in 2025 and your invested savings fell to $35,000 in a crash, you are either buying a smaller home or delaying indefinitely. Use HYSA or CD rates for any goal with a firm timeline under 3 years.

| Goal | Target Amount | Timeline | Monthly Needed at 4.60% | Vehicle |
|---|---|---|---|---|
| Emergency fund (3 months) | $15,000 | 24 months | $621 | HYSA |
| Car down payment | $5,000 | 18 months | $273 | HYSA |
| Home down payment (10%) | $30,000 | 36 months | $784 | HYSA or CD |
| Vacation fund | $8,000 | 24 months | $323 | HYSA |
| Home repair reserve | $10,000 | 30 months | $308 | HYSA |
The 5-Year Boundary: When to Add Stocks
For goals 5 or more years away, a modest stock allocation (20% to 40%) alongside HYSA or CD savings is reasonable. Not because stocks are safe, but because a 5-year horizon provides some recovery time if markets decline in year 1 or 2. For goals under 3 years: no stocks. For exactly 3 to 5 years: allocate conservatively with stocks at 20% maximum, the remainder in safe savings vehicles.
How to Model a 3-Year Goal in the Investment Calculator
Enter your current savings as starting balance. Enter your planned monthly contribution. Enter 4.25% to 4.50% as the return rate (HYSA rate, not equity rate). Set the time period to 3 years. The calculator produces an accurate projection for a safe savings vehicle. This approach uses the calculator's compound interest mathematics while inputting an appropriate rate for the risk level of the goal.
If you have a firm date for a large purchase (house closing in exactly 18 months), a CD matching that term often provides slightly higher rates than a HYSA and protects against HYSA rate decreases as the Fed potentially cuts rates. Use the calculator with the CD rate (currently 4.50% to 5.10% for short terms). The CD essentially guarantees the projection assuming you do not withdraw early.
