§01What is
Understanding the Present Value of Cash Flows
The Present Value of Cash Flows computes PV total from 4 inputs: year 1, year 2, year 3, rate (%). PV of cash flow series.
Quick calculators for the math that shouldn’t need a notepad — instant, accurate, private to your browser.
The Present Value of Cash Flows sits in that toolkit — it PV of cash flow series. Enter your numbers above and the result updates instantly; every step of the math is shown in the Derivation panel so you can see exactly how the answer was reached.
Apply the formula to a realistic set of inputs: Year 1 = 500, Year 2 = 700, Year 3 = 1000, Rate (%) = 8.
01Start by noting the input — Year 1: 500.
02Start by noting the input — Year 2: 700.
03Start by noting the input — Year 3: 1000.
04Start by noting the input — Rate (%): 8.
05Substitute these values into the formula: t / (1+r / 100)^(1)+a / (1+r / 100)^(2)+n / (1+r / 100)^(3)
06Compute PV total: the calculator returns 1856.93.
07Cross-check the answer by opening the Derivation panel above — every line of math is shown so you can follow the computation end-to-end.

Common Present Value of Cash Flows Problems
The formula gets rearranged depending on which variable you need. Here are the patterns you’ll run into in the real world — find the one that matches your problem and follow the worked steps.
01 · PATTERN
Year 1 halved
c1 = 250 (from 500)
Keep every other input at its default and halve the year 1. See how pv total responds.
01New Year 1: 250
02Baseline PV total: 1856.93
03New PV total: 1625.45
04PV total decreases by 12.5% → use this sensitivity to plan for real-world variation.
02 · PATTERN
Year 1 doubled
c1 = 1000 (from 500)
Keep every other input at its default and double the year 1. See how pv total responds.
01New Year 1: 1000
02Baseline PV total: 1856.93
03New PV total: 2319.9
04PV total increases by 24.9% → use this sensitivity to plan for real-world variation.
03 · PATTERN
Year 2 halved
c2 = 350 (from 700)
Keep every other input at its default and halve the year 2. See how pv total responds.
01New Year 2: 350
02Baseline PV total: 1856.93
03New PV total: 1556.86
04PV total decreases by 16.2% → use this sensitivity to plan for real-world variation.
04 · PATTERN
Year 2 doubled
c2 = 1400 (from 700)
Keep every other input at its default and double the year 2. See how pv total responds.
01New Year 2: 1400
02Baseline PV total: 1856.93
03New PV total: 2457.07
04PV total increases by 32.3% → use this sensitivity to plan for real-world variation.
