Formulas used

This calculator is built on the following relationships between its quantities. Each one can be solved for any of the values it contains, which is why you can leave any single field empty and have it calculated from the others:

Final_balance = Initial_balance × (1 + r1 / m) ^ (m × t)

Final_balance = Initial_balance × 2.7182818284590452353602874713527 ^ (r2 × t)

Surplus = Final_balance - Initial_balance

Final_balance = Initial_balance × (1 + r3 / 1) ^ (1 × t)

Interest_rate = if_else(m_2>0, r1, r2)
