How to Use the US Savings Calculator

Enter your initial deposit, monthly contribution, annual interest rate (US average savings 0.4%, HYSA 4%, S&P 500 7-10%), and savings period. The calculator will estimate your total contributions, interest earned, and future balance with monthly compounding - typical for US banks, 401k, Roth IRA.

Formula: Future = Initial×(1+r)^n + Monthly×((1+r)^n-1)/r

Example - US

For an initial deposit of $5,000, a monthly contribution of $200, a 5% annual interest rate, and a 10-year period (120 months), monthly rate = 0.0041667, growth = (1.0041667)^120 = 1.647, Future = 5000×1.647 + 200×(0.647/0.0041667) = $39,310. Example for US retirement savers.
