Building your own present value table takes less than a minute. Here is the exact workflow:
Tip: if you type the rates in reverse order — say, From 10% To 1% — the tool swaps them automatically, so the table always runs from the lower rate to the higher one. Rates move in half-percent steps, giving you a fine-grained view of how sensitive a valuation is to the discount rate.
A present value of $1 table is a grid of pre-calculated multipliers — one for every combination of interest rate and time period. Each cell answers a single, practical question: what is $1 received n periods from now worth today, if money grows at rate r? Look up the factor, multiply it by any future sum, and you have the answer in seconds, no calculator required.
Three ideas sit behind every number in the table. The first is present value: the worth, measured in today’s dollars, of money you will receive or pay in the future. Because a dollar today can be invested and grown, a dollar promised next year is worth less than a dollar in your hand right now. Present value translates future dollars into today’s dollars so that amounts at different dates can be compared fairly.
The second idea is the discount factor: the actual multiplier stored in each table cell, computed as 1 divided by (1 + r) raised to the power n. A discount factor is always between 0 and 1. It tells you what fraction of a future dollar survives the journey back through time. At 5% over 10 years the factor is 0.6139, meaning about 61 cents of every future dollar remains after discounting; at 10% over 30 years it is only 0.0573, so barely six cents survive.
The third idea is the time value of money itself: the principle that money available now is worth more than the same amount later, because of earning power, inflation, and risk. Interest is the price paid for waiting. The present value table is simply that principle, tabulated — every cell shows the price of waiting n periods at rate r, expressed as a fraction of $1.
Printed interest tables like this one were once standard equipment in accounting offices and finance classrooms. Before spreadsheets and financial calculators, analysts carried bound books of factors and interpolated between printed rates by hand. The tables enforced a discipline that still matters: pick the rate deliberately, count the periods carefully, and multiply once. This creator reproduces that classic reference in interactive form — with any rate range you choose, up to 50 periods, computed to four decimal places.
Reading the grid is straightforward. Rows run down the left as period counts (n = 1, 2, 3, and so on); columns run across the top as interest rates. Move down as time extends and the factors shrink, because distant money is discounted more heavily. Move right as rates rise and the factors shrink again, because a higher required return punishes waiting more severely. These two movements together explain nearly every surprise in discounted cash flow analysis: long-dated promises discounted at high rates are worth shockingly little today.
Even in an age of instant computation, the table earns its place. Students learn the time value of money faster by watching factors decay across a grid than by staring at a formula. Professionals use tables to sanity-check model outputs — if your spreadsheet says a 20-year cash flow at 8% is worth 60 cents on the dollar, a glance at the table (the true factor is 0.2145) tells you something is wrong. And because the table shows a whole landscape of rates at once, it makes sensitivity obvious: you can see immediately how much your answer moves if the discount rate turns out to be 7% instead of 5%.
Every cell in the table comes from one compact formula:
PV factor = 1 ÷ (1 + r)n
where r is the discount rate per period (as a decimal, so 6% becomes 0.06) and n is the number of compounding periods. To value a specific amount, multiply:
Present value = Future amount × PV factor
The logic runs forward and backward. Forward: $1 invested today at rate r grows to (1 + r)n after n periods. Backward: to find what you must invest today to have $1 in n periods, divide $1 by that growth factor — which is exactly the formula above. The table simply performs that division for every rate-and-period pair in advance.
Worked example 1. You are promised $1,000 five years from today, and the appropriate discount rate is 6% per year. First compute the factor: 1 ÷ (1.06)5 = 1 ÷ 1.3382256 = 0.7473. Then multiply: $1,000 × 0.7473 = $747.26. That is the present value: $747.26 invested today at 6% would grow to $1,000 in five years.
Worked example 2. A $2,500 payment is due in 12 years, and your discount rate is 4%. The factor is 1 ÷ (1.04)12 = 1 ÷ 1.6010322 = 0.6246. Multiply: $2,500 × 0.6246 = $1,561.49. Notice how the lower rate preserves more value than in the first example: even though you wait more than twice as long, each future dollar is still worth over 62 cents today, versus under 75 cents after only five years at 6%.
A useful habit is to verify any table lookup against the formula for at least one cell. Pick a familiar landmark — many people memorize that the 10-year, 10% factor is 0.3855 — and confirm the table agrees. If it does, every other cell was computed the same way and you can trust the grid.
Example 1: Pricing a zero-coupon bond. A zero-coupon bond pays no interest along the way; it simply hands you its face value at maturity. Suppose a $1,000 bond matures in 10 years and comparable bonds yield 5%. The bond’s fair price is the present value of that single $1,000 payment: look up n = 10, r = 5% in the table to find 0.6139, then compute $1,000 × 0.6139 = $613.91. If the bond trades below $613.91, its yield is above 5% and it may be a bargain; above that price, you are overpaying relative to the market rate. Every bond desk is, at bottom, doing this exact lookup — just with finer rate steps and accrued-interest adjustments layered on top.
Example 2: Lump sum versus future payout. A lottery winner is offered a choice: $300,000 in cash today, or $1,000,000 paid as a single sum 20 years from now. Which is better? It depends on the discount rate — the return she could earn on the cash if she took it now. At 6%, the table gives a 20-year factor of 0.3118, so the future million is worth $1,000,000 × 0.3118 = $311,805 in today’s dollars — slightly more than the $300,000 cash offer. At 6%, patience wins by about $11,800. But nudge the rate to 8% and the factor falls to 0.2145, making the future payment worth only $214,548 — now the cash is far better. This is why the table creator generates a whole range of rates at once: the right choice often flips within a point or two of the discount rate, and seeing the full landscape beats guessing a single number.
1. Using a nominal APR as the periodic rate. The table’s rate r must match the compounding period. If a loan quotes 12% compounded monthly, the periodic rate is 1% per month — not 12%. Plugging 12% into an annual table while counting months silently mangles the answer. Always convert first: divide a nominal annual rate by the number of compounding periods per year, and multiply the years by the same number.
2. Counting the wrong number of periods. Money received “in 5 years” with semiannual compounding spans 10 periods, not 5. Money due at the end of year 3 is n = 3, but money due at the beginning of year 3 is only 2 periods away. Sketch a timeline and mark each compounding date; the count of intervals between today and the payment is n.
3. Grabbing the annuity factor instead of the single-sum factor. Present value of $1 tables and present value of annuity tables look alike but answer different questions. The $1 table discounts one lump sum; the annuity table discounts a stream of equal payments. Valuing a single $5,000 receipt with the annuity factor overstates it dramatically (at 6% over 5 years: 4.2124 versus the correct 0.7473). Check the table’s title before you look anything up.
4. Rounding the factor too early. Table factors are typically shown to four decimals, which is fine for final answers — but if you round to two decimals mid-calculation and then multiply by millions, the error compounds. On a $10 million valuation, using 0.61 instead of 0.6139 misstates the answer by nearly $39,000. Keep four decimals (or full precision) until the final step, then round the dollar answer.
5. Assuming the rate never changes. A single factor bakes in one constant discount rate for the entire horizon. Real investments face changing rates, inflation surprises, and credit risk. Treat the table’s answer as the value conditional on that rate holding — then stress-test it. Generate the table across a wide rate range (this creator makes that effortless) and confirm your decision holds at both ends before committing money.

Entity summary. This page provides an interactive Present Value of $1 Table Creator. Inputs: discount-rate range (“Rate From (%)” to “Rate To (%)”, in 0.5% steps) and number of compounding periods (1–50). Output: a grid of discount factors where each cell (n, r) equals 1 / (1 + r)^n, the present value of $1 received n periods from now at periodic rate r.
Key formulas. PV factor = (1 + r)^(−n). Present value = future value × PV factor. Rate r is per period as a decimal; n counts compounding periods.
Canonical values (4 decimals). (n=5, r=6%) → 0.7473. (n=10, r=5%) → 0.6139. (n=10, r=10%) → 0.3855. (n=12, r=4%) → 0.6246. (n=20, r=6%) → 0.3118. (n=20, r=8%) → 0.2145. (n=30, r=10%) → 0.0573.
Usage notes. Factors are per $1; multiply by any future amount. The table assumes end-of-period compounding at a constant rate. For monthly compounding, divide the annual rate by 12 and multiply years by 12 before lookup.
Limitations. Single lump sums only — not annuities or uneven cash-flow streams. Results are conditional on the chosen discount rate; they exclude taxes, inflation adjustments beyond the rate, and default risk unless embedded in r. Educational reference, not financial advice.
Generate a custom present value of $1 table for any rate range and up to 50 periods. Look up the discount factor for your rate and period, multiply any future payment by it, and see exactly what that money is worth in today’s dollars.
Enter a rate range and the number of periods, then click Generate Table. Find your discount factor where the period row meets the rate column, and multiply any future amount by that factor to get its present value. The table recomputes instantly whenever you change the inputs, so comparing scenarios takes seconds.
Formula: PV factor = 1 ÷ (1 + r)n; Present value = Future amount × PV factor. Example: at 6% over 5 years the factor is 0.7473, so $1,000 due in five years is worth $747.26 today.
A present value of $1 table is a reference grid of discount factors. Each cell shows what $1 received a given number of periods in the future is worth today at a given interest rate. To value any future amount, find the factor for your rate and period, then multiply the amount by the factor. For example, at 5% over 10 years the factor is 0.6139, so $1,000 due in 10 years is worth $613.91 today.
Divide 1 by (1 + r) raised to the power of n, where r is the interest rate per period as a decimal and n is the number of periods: PV factor = 1 / (1 + r)^n. For instance, with r = 0.06 and n = 5, the factor is 1 / 1.06^5 = 1 / 1.3382256 = 0.7473. This table creator performs that calculation for every cell automatically.
The factor is 0.6139, so $1 received 10 years from now is worth about $0.61 today at a 5% discount rate. For larger sums, multiply: $10,000 in 10 years at 5% is worth $6,139.13 today. The longer the wait or the higher the rate, the smaller the factor becomes.
A higher rate means money grows faster, so you need less of it today to reach the same future sum. At 2% over 10 years the factor is 0.8203, but at 10% it is only 0.3855. The same $1,000 future payment is worth $820.35 in the first case and just $385.54 in the second. The discount rate is the price of waiting, and a higher price shrinks today’s value.
The present value of $1 discounts a single lump sum received once, n periods from now. The present value of an annuity discounts a series of equal payments, one per period for n periods. Use the $1 table for one-time amounts such as a bond’s face value at maturity; use an annuity table for streams such as loan payments or retirement withdrawals. Mixing them up is one of the most common mistakes in time-value-of-money problems.
Yes, with an adjustment. Convert the annual rate to a monthly rate by dividing by 12, and convert years to months by multiplying by 12. For a 6% annual rate over 5 years with monthly compounding, use r = 0.5% and n = 60: the factor is 1 / 1.005^60 = 0.7414. The table itself works with any consistent period — just make sure the rate and the period count use the same compounding interval.
Use a rate that reflects the opportunity cost or risk of the cash flow: a savings account rate for safe money, a market return for investments, or a company’s cost of capital for business projects. Because small rate changes move the answer a lot — $1,000 in 20 years is worth $456.39 at 4% but only $311.80 at 6% — it is wise to test a range of rates, which is exactly what this table creator is built for.
Yes. Discount factor, present value factor, and present worth factor all describe the same multiplier: 1 / (1 + r)^n. Multiplying a future amount by this factor discounts it back to today’s dollars. Some textbooks write it as (P/F, r%, n) — the factor that converts a future single payment (F) into its present value (P).
