Comparing senior care agencies in Sterling requires looking past the headline hourly rate. The 5-factor framework — base rate, premium hours, mileage, assessment fees, and minimum visit length — produces the true monthly cost. Sterling-area agencies vary 20–30 percent on all-in cost even when headline rates look similar.
Factor 1: Base hourly rate in Sterling
Sterling 2026 ranges:
- Companion-only (non-CHHA): $25–$32/hour
- CHHA-certified: $30–$42/hour
- Memory care specialist (CDP): $35–$50/hour
The base rate is the starting point but not the full picture.
Factor 2: Premium hours
Standard Sterling premiums:
- Evenings (after 6 PM): +10–15%
- Weekends: +10–25%
- Overnights: +15–25%
- Holidays: +50–100% (list of holidays varies)
For a schedule with significant evening or weekend hours, premium math can add 10–20% to monthly cost.
Factor 3: Mileage and travel
Most Sterling agencies bill mileage at the federal IRS rate ($0.67/mi in 2026) for caregiver-driven errands. For a senior using significant transportation services, mileage can add $30–$100/month. Some smaller agencies don’t bill mileage as a competitive differentiator.
Factor 4: Assessment and revision fees
Some Sterling agencies charge:
- Initial in-home assessment: $100–$300
- Care plan revisions: $50–$200 per revision after the first
- Periodic reassessments (annual or after status change): $100–$200
Reputable agencies often absorb assessment cost as part of sales process. Charging for revisions is more common.
Factor 5: Minimum visit length
Most Sterling agencies have 3 or 4 hour minimum per visit. The minimum affects both schedule flexibility and effective hourly cost. Shorter actual visits (e.g., a 2-hour bath assistance) still pay for the minimum — so the effective hourly rate is higher than the base.
