What interest rate should I use?
Use APY from your actual savings vehicle: high-yield savings (4-5%), money market, or CDs. Never use hoped-for stock market returns for conservative planning.

Calculate how much you need to save to reach your financial goals
Estimate the amount and time needed to achieve your savings goals
A savings goal calculator projects how long it takes to reach a specific monetary target. It combines current savings, monthly contributions, and interest to project timeline. It also accounts for inflation showing how rising costs affect your target.
The calculator starts with current savings, adds monthly contributions each month while calculating compound interest on the growing balance. It tracks accumulation until reaching your goal and generates alternative scenarios.
Future Value = Present Value × (1 + r/12)^n + PMT × [((1 + r/12)^n - 1) / (r/12)]. For finding required payments, solve for PMT given target future value. Inflation adjustment: Adjusted Goal = Goal × (1 + inflation)^years.

Inflation reduces purchasing power. If your goal is $50,000 in 5 years at 2.5% inflation, you'll need about $56,400 for the same buying power.
Contributions are dollars you save from income. Interest is free money the bank pays. Over 5 years at 4%, you might contribute $12,000 but earn $1,300 in interest.
