How to use the present value calculator
- Future goal: target balance at the end of the plan.
- Monthly contribution: fixed deposit each month until then (0 for lump-sum-only).
- Discount rate: expected annual return. Years: time to the goal.
- Present value needed is what you would need today at that rate, net of planned contributions.
What discounting means
A higher discount rate lowers today’s required lump sum because future dollars are worth less in present terms—holding contributions constant.
Example
$100,000 goal in 15 years at 5% with no monthly deposits → present value on the order of $48k (see calculator).

Frequently asked questions
What is present value (PV)?
Present value converts a future amount into today’s equivalent dollars at your discount rate. This page answers: if you want a target balance in the future while making fixed monthly deposits, how much lump sum you would need today. Results change with the goal, years, rate, and monthly contribution.
What discount rate should I use?
Use a long-run average annual return you consider plausible for this money—lower for conservative savings-like assumptions, higher for long-horizon growth assumptions. A higher discount rate lowers today’s required PV because future dollars count for less. Planning only—not a guarantee; no taxes, fees, or inflation modeling here.
How do monthly contributions affect present value?
Each monthly deposit is discounted and credited toward the goal, so the lump sum needed today drops. When deposits are greater than zero, compare “upfront with no monthly saves” versus “reduction thanks to monthly saves.” Set monthly contribution to 0 for lump-sum-only planning.
How does this pair with the future value calculator?
They are two directions of the same time-value relationship: the future value calculator projects forward from today’s deposit and contributions; this page discounts a future goal backward. Use the result link to open FV with matching inputs as a forward check.
How is this different from the compound interest calculator?
The compound interest calculator adds schedules, uneven flows, inflation, and tax options. This page is a TVM shortcut: fixed goal, fixed monthly deposit, one discount rate—no month-by-month table. Use compound interest when you need a schedule or export.
What assumptions does this calculator make?
Monthly compounding; contributions at the end of each month (ordinary annuity); constant rate and horizon; no withdrawals, extra lump sums, or taxes. Fractional years convert to whole months. If your product uses different timing, treat results as approximate.
What if my goal or plan changes?
Edit the goal, years, rate, or monthly contribution—the results update live. For retirement spending targets, try the third mode on the retirement calculator; this page fits a single future balance goal.
