How it works
Future value: A = P(1 + r/n)nt, plus contributions C × (((1 + r/n)nt − 1) / (r/n)) when you add money each compounding period. Contributions are assumed at the end of each period. Note: the worked example for this calculator is PKR 164,530.89 — computed directly from (1 + 0.10/12)60.More free tools: Financial Calculators hub — car finance, loan vs invest, Apna Ghar and more.
