What it calculates
The “Obligacii Convexity Rassh” calculator computes Convexity from 4 parameters: p_(y−δ), p_(y+δ), p₀, δy.
Used by investors to estimate returns, project savings, and analyze a portfolio.
Example calculation
With parameters P_(y−Δ) = 980, P_(y+Δ) = 920, P₀ = 950, Δy = 0.01 the result is 0 ((P− + P+ − 2P₀) / (P₀·Δy²)).
How to use
- Enter p_(y−δ), p_(y+δ), p₀ and δy — each field above is adjustable with a slider.
- Convexity is calculated automatically as you type.
- Check the worked example below to see the formula applied to real numbers.

FAQ
What is compound interest?
Compound interest means you earn returns not only on your original principal but also on previously earned interest. Formula: A = P · (1 + r/n)^(n·t). Over long periods this produces exponential growth.
How much do regular contributions matter?
A lot. Adding a fixed amount every month and reinvesting earnings dramatically increases the final value, especially over 20–30 years, because each contribution compounds for the remaining term.
What is the Rule of 72?
A quick estimate for doubling time: years ≈ 72 / annual return %. At 8% your money doubles in about 9 years; at 12%, in about 6 years.
What return rate should I assume?
Historically the S&P 500 has returned about 10% per year before inflation (around 7% after). Use a conservative figure for planning and remember that past performance does not guarantee future results.
