What is 5% per week as an annual return?

Compounded, 5% per week is 1,164% a year. Interest is multiplied, not added, so the yearly figure is (1 + 5/100) raised to the power of 52, minus one.

How long would 5% per week take to double my money?

About 14 days. At a weekly rate that high the balance reaches a million dollars from a thousand in 5 months, which is why the number is only ever advertised, never audited.

Is 5% per week realistic?

No supervised product guarantees anything close. A weekly percentage is quoted because it sounds small, but 1,164% a year is far above an insured deposit, above a Treasury bill, and above the best long-run professional record. A fixed promise at that level has to be paid from someone else's deposit.

What does 5% per week actually compound to?

Taken at face value and multiplied out, 5% per week is 1,164% a year. That is about 291x what you would get from a three-month Treasury bill that pays around 4% and a government-insured deposit around 3.5%. The arithmetic below assumes every payment arrives on time, which is the assumption that fails in practice, not the compounding.

What this rate means

Mathematically impossible to sustain

Compounded, this turns a small deposit into more money than exists. Nobody has ever sustained it. The advertised number is bait.

5% per week against what is guaranteed

Reference levels: long-run approximations, October 2026. A multiple of "-" means the comparison does not apply.

Reference level	Rate	This rate in multiples
Insured bank deposit (US, FDIC)	3.5% a year (guaranteed)	333x
3-month US Treasury bill	4.0% a year (guaranteed)	291x
US inflation (consumer prices)	2.5% a year (not investable, measures erosion)	466x
S&P 500, long-run average	10.0% a year (not guaranteed to anyone)	116x
Best long-run professional record (Buffett, decades)	20.0% a year (not guaranteed to anyone)	58.2x

The red line

A guaranteed return higher than a Treasury bill or an insured deposit cannot exist. Every dollar paid above the risk-free rate is paid for with risk, leverage, or other people's deposits. A published promise of a fixed return above the risk-free rate is the definition of a return trap.

No published entry on this register currently quotes a rate in this range. The arithmetic above still applies to any offer that does.
