Why this page exists

Investment gains are easier to plan around when purchase price, sale price, fees, and a tax-rate assumption turn into one clear estimate instead of a guess about what the sale might really leave behind. This calculator helps visitors estimate total gain, taxable gain after fees, capital gains tax, and after-tax proceeds from a simple planning model.

Calculator

Capital gains tax calculator

Estimate total gain, taxable gain after selling fees, capital gains tax, and after-tax proceeds from a simple sale scenario.

Result

$975.00

Estimated capital gains tax based on gain, optional selling fees, the holding-period label selected, and the planning tax rate entered.

Estimated capital gains tax$975.00

Total gain$7,000.00

Taxable gain after fees$6,500.00

Estimated after-tax proceeds$20,525.00

Rate assumptionLong-term planning rate at 15.00%

$22,000 sold against a $15,000 basis creates a gain of about $7,000.00 before fees.
After subtracting $500.00 of selling fees, the taxable gain in this simple estimate comes to about $6,500.00.
Applying the 15.00% planning tax rate produces an estimated capital gains tax of about $975.00.

This is a planning estimate only. Actual capital gains tax rules vary by country, state, filing status, deductions, holding period, and how the asset's basis and selling costs are treated.

How it works

What the calculator is doing

Enter the purchase price or cost basis, sale price, holding-period label, tax rate, and any optional selling fees.

The calculator finds the gain, subtracts fees if entered, and applies the planning tax rate to any positive taxable gain.

It shows the total gain, taxable gain after fees, estimated capital gains tax, and estimated after-tax proceeds.

Understanding your result

This is a planning estimate only. Real capital gains tax rules vary by country, state, filing status, deductions, and how basis, fees, and holding period are treated.

Examples

Ways people use this tool

Example scenarios help turn a quick estimate into a more useful comparison or planning step.

Check how much a sale may leave after tax

A quick estimate can make it easier to compare the gross sale price with what may actually be left after fees and tax.

Compare short-term and long-term planning rates

Changing the holding-period label and tax rate can show how much the estimate shifts under different assumptions.

Review a sale before deciding whether to hold

Seeing after-tax proceeds can make it easier to compare selling now with keeping the asset longer.

FAQ

Common questions

How does this calculator estimate capital gains tax?

It subtracts purchase price from sale price, subtracts any selling fees entered, and applies the planning tax rate to any positive taxable gain.

Why can selling fees matter?

Selling fees reduce the amount left from the sale and can reduce the taxable gain in this simple estimate.

Is this a tax filing tool?

No. It is a planning tool only, because real capital gains tax rules depend on location, filing details, exemptions, and how the sale is reported.
