| Typical monthly income (low / median / high) | $3 / $30 / $400 |
Realistic expectations
Most people who try this earn around $3–$30 per month in the first year; the high figure of $400 is a ceiling for a focused solo operator, not a typical outcome. The chance of receiving at least one real payout within six months is rated 10/10. Expect the first payment after 30–60 d.
How it works
You move cash from a zero-interest account into an insured high-yield savings account, a government money-market fund, or buy short-dated government bills directly (TreasuryDirect, Tesouro Direto, NS&I, Singapore T-bills, Nigerian/Kenyan T-bill auctions). The bank or government pays interest because it is borrowing your money. Returns scale with capital; a baseline, not a business.
Platforms: Online banks (Marcus, Ally, Chase UK, Trade Republic), TreasuryDirect, Tesouro Direto, Vanguard/Fidelity MMFs, local T-bill auctions
Resources & business plan
What you need to start
| Resource | Amount |
|---|---|
| Time to launch | 1 hours |
| One-time cash | $1,000 |
| Recurring fixed cost | $0 / month |
| Tools | online high-yield savings account, money-market fund or TreasuryDirect (free) |
| Skills | none beyond comparing rates and deposit-insurance limits |
| Equipment | smartphone |
| Accounts | bank or broker account + KYC; linked current account |
How the money is made (unit economics)
| Metric | Value |
|---|---|
| Unit | per $1,000 deposited, per year |
| Typical price per unit (low / median / high) | $20 / $40 / $45 |
| Direct cost per unit | $0 |
| Platform fee | 0% |
| Gross margin (median case) | 100% |
| Human hours per unit after automation | 0 |
Annual interest on $1,000: ~2% in euro accounts (ECB deposit rate 2.50% since 16 Sep 2026), ~3.5% in GBP accounts (Bank Rate 3.75%, Sep 2026), ~4.0-4.3% in USD T-bills/HYSA (Oct 2026 auctions 4.1-4.35%), so $20-$45. Emerging-market local rates are higher but carry FX/inflation risk. Profit depends on capital, not effort: $1,000 earns ~$3/month; ~$30,000 is needed for $100/month.
Break-even
| Metric | Value |
|---|---|
| Monthly fixed cost | $0 |
| Units per month to break even | 0 |
| Typical months to break even | 1 |
| Months to recover startup cash | 0 |
Fixed cost = recurringMonthlyUsd only (startup cash not amortised). No fixed cost. The deposit is not spent and can be withdrawn, so startup recovery is not applicable; first interest posts within ~30 days.
Market conditions (Nov 2026)
| Factor | Assessment |
|---|---|
| Demand trend | stable |
| Competition | low |
| Effect of AI | neutral |
| Price pressure | falling |
| Chance of real net profit within 12 months (≥ $100/month where the plan can pay that much) | 95% |
| Typical net profit at month 12 (low / median / high) | $3 / $30 / $400 |
Profit is almost certain in nominal terms because interest is contractual and deposits are insured up to limits, but it scales only with the capital you bring, not with effort or skill. USD rates have been drifting down with policy cuts; after inflation the real return is near zero. Likelihood is for any positive net return; reaching $100/month needs roughly $30,000 at 4%.
Pricing strategy
Not priced by you: move cash to the best insured rate and re-check quarterly; ladder T-bills to lock rates if cuts are expected.
Path to profit
- Month 0: open an online HYSA/MMF and move idle cash (capital $1,000+, kept)
- Month 1: first interest (~$3 per $1,000)
- Month 3-6: automate a monthly sweep of surplus cash; income grows only with deposits
- Month 6-12: optional T-bill ladder; expect ~$40 per $1,000 per year

Payout path
- Methods: interest credited to account, maturity proceeds to bank
- Minimum payout: None
- Frequency: monthly interest or at maturity
- Typical delay: 30 days
- Notes: Savings interest posts monthly; T-bills pay at maturity (4-52 weeks).
Full cycle (setup → earn → bank account)
- Open HYSA or MMF/T-bill account
- Transfer savings
- Interest accrues
- Maturity/withdrawal
- Funds to bank
What can be automated
- Auto-sweep idle balances above a threshold into HYSA/MMF
- Auto-roll T-bill ladders (TreasuryDirect auto-reinvest)
- Rate-monitoring script to switch banks when rates drop
Unavoidable manual steps
- Account opening/KYC
- Linking bank accounts
Legality & compliance
Legal everywhere; Islamic equivalents (profit-sharing deposits, sukuk) exist.
- Compliance requirements: KYC; report interest as taxable income; stay under deposit-insurance limits per bank
- Platform availability: Some interest-bearing option exists in every reference country. USD rates checked Nov 2026: US Treasury bill auctions in Oct 2026 cleared at about 4.1-4.35% (13-week ~4.15-4.2%); the FDIC national average savings rate is only 0.38% (Oct 2026), so you must pick an online high-yield account or MMF. Local-currency rates are much higher in Brazil, Nigeria, Kenya, Argentina but with inflation/FX risk. Income = capital x rate (e.g. $10k at 4% = ~$33/month); capital is required and $1,000 yields only ~$3/month.
Risks
- Inflation exceeding rate
- Rate cuts
- Bank failure above insurance limits
- Currency devaluation in emerging markets
Evidence that people get paid
Interest is contractually paid; TreasuryDirect/Fiscal Data auction results (Oct 2026 bills ~4.1-4.35%) and FDIC national rates (savings avg 0.38%, rate cap 4.63%, Oct 2026) document yields.
