How it is calculated
- The yearly return becomes an equivalent monthly rate: (1 + r)^(1/12) − 1.
- Each month: balance × (1 + monthly rate), then the deposit is added.
- Gains = final amount − total paid in.
Example
1,000 at 5% a year for 10 years, no deposit: 1,000 × 1.05^10 ≈ 1,628.89.
Good to know
- The return is an assumption: it is never guaranteed and can be negative.
- No tax, fees or inflation.
- This is not investment advice.
