Free future value of savings calculator. Project your savings balance over time with and without regular contributions at any interest rate and compounding frequency.
The Future Value of Savings Calculator projects your savings balance at any point in the future. Enter your current balance, planned contributions, interest rate, and time horizon to see the projected end balance with a clear breakdown of contributions versus interest earned.
This projection tool helps you visualize where your savings are headed and make informed decisions about your financial plan. It shows the future value both with and without contributions, so you can see how much your deposits add compared to interest alone.
Use this calculator for long-range planning, comparing savings strategies, or simply understanding the trajectory of your current savings behavior. The year-by-year table breaks down how your money grows and how the contribution-to-interest ratio shifts over time. Most people underestimate how dramatically compounding impacts their savings. A small increase in the interest rate or contribution amount can add thousands of dollars to the final balance over a 10 or 20-year horizon. Seeing those differences in black and white makes educated decisions far easier.
Seeing your projected future balance provides powerful motivation and perspective. It shows whether your current savings trajectory will meet your needs or fall short, allowing you to adjust early rather than discovering a shortfall when it is too late. The dual projection (with and without contributions) also demonstrates the enormous value of consistent deposits.
With contributions: FV = PV(1+r/n)^(nt) + PMT × [((1+r/n)^(nt) – 1) / (r/n)] Without contributions: FV = PV(1+r/n)^(nt) Interest earned = FV – PV – (PMT × 12 × t) where PV = present value, r = annual rate, n = compounding periods, t = years, PMT = contribution per period
Result: Future balance: $82,349
Starting with $15,000 and adding $400 monthly at 4.5% APY compounded monthly for 10 years: total contributions are $63,000 ($15,000 + $400 × 120). Interest earned is $19,349. Without contributions, the $15,000 alone would grow to only $23,255. The $48,000 in monthly deposits plus compounding interest add $59,094 to the final balance.
The difference between these two projections is striking. A $15,000 balance at 4.5% without any contributions grows to $23,255 in 10 years. Adding just $400 per month transforms that into $82,349. The contributions themselves total $48,000, and compound interest on both the balance and the growing contributions adds another $11,094 beyond what the principal alone would earn.
Future value projections form the foundation of financial planning. They help answer questions like: Will I have enough for a down payment in 5 years? How much will my emergency fund be worth in 3 years? Should I increase contributions now or later? Run multiple scenarios to understand the range of possible outcomes.
In the year-by-year table, notice how interest earned each year increases even if contributions stay constant. This is compound growth in action: as the balance grows, the interest earned grows proportionally. In the early years, contributions dominate growth. In later years, interest increasingly takes over, creating an accelerating curve.
Future value (FV) is the projected worth of your current savings at a specific point in the future, given an interest rate and time period. It accounts for compound interest and any regular contributions, showing your expected ending balance.
Long-term projections assume a constant interest rate and contribution, which is unlikely in practice. They are best used as directional guides rather than precise predictions. Rerun the projection annually with updated rates and balances for more accurate tracking.
Both views are useful. Without contributions shows the power of compound interest on your existing balance. With contributions shows the realistic trajectory if you continue saving regularly. The difference between the two highlights how valuable consistent deposits are.
At typical savings rates (3–5%), the difference between daily and monthly compounding is very small — a few dollars per year on a $10,000 balance. The APY already accounts for compounding, so if you use APY rather than APR, the frequency matters less.
You can, but investments have variable returns and risk. This calculator assumes a fixed rate, which is appropriate for savings accounts, CDs, and bonds. For investments, consider using a dedicated investment growth calculator that models volatility and range of outcomes.
Use the current APY on your savings account for short-term projections (1–3 years). For longer projections, consider using a conservative estimate 0.5–1% below current rates to account for potential rate decreases. For a realistic range, run projections at 3 different rates.
